MARANA, Ariz. -- Here are recaps from first-round matches on Thursday at the World Golf Championships-Accenture Match Play Championship:
Donald def. Siem, 1 up
Luke Donald staved off the kind of upset bid that caught up with the world's No. 1 and 2 players late Thursday when he won the 18th hole to beat Marcel Siem.
Donald made six birdies, including a pair on the last two holes -- the first from 9 feet to halve the 17th and the second from 7 for the win. Three of those birdies had come on the front nine as the Englishman built a 2-up advantage.
But Siem, who was making his World Golf Championships-Accenture Match Play Championship debut, began to assert himself on the back nine. The pony-tailed German won the 10th hole with a chip-in birdie, the 11th when Donald bogeyed and the 12th with a 28-foot birdie putt to take his only lead of the day.
"I didn't worry because I was hitting good shots still," the Englishman said. "I hit a couple left shots on the back nine but drove it great today, hardly missed a fairway, hit a lot of solid iron shots and putted well. I obviously made it tough on him, too, and I just ... felt good about my game, so I wasn't worried when I went 1 down on 12."
Donald, who was the 2011 champion at Dove Mountain, answered with a 6-foot birdie putt at the par-5 13th to even the match. The next four holes were halved with a bogey, two pars and a birdie, before Donald converted at No. 18 for the win after Siem missed from 13 feet.
"I had to finish strong against Marcel," Donald said. "He pushed me all the way. He really played solid today. I threw six birdies in, but he had a couple chip-ins and holed some long putts and made it very difficult. It's always nice to get through that first round, and sometimes having a tough match is a good thing."
Donald faces Scott Piercy, a 4-and-3 winner over Paul Lawrie in his Accenture Match Play Championship debut, in Friday's second round.
Lowry def. McIlroy, 1 up
Shane Lowry, who grew up playing against Rory McIlroy, upset the world No. 1 on Thursday in the first round.
Lowry made his run on the back nine, winning the 12th hole with a chip-in birdie and the 13th with an eagle to get a 2-up edge. He bogeyed the 14th hole but got that back with a concession at the 15th after McIlroy found three different bunkers, then parred in for the win.
"Obviously it was always going to be a tough match for me against Rory today, but playing against the world No. 1, I'm feeling quite good now, but it's important not to get too high now because it's only the first round, and I've got another match tomorrow and really looking forward to playing that," Lowry said.
McIlroy grabbed a 2-up lead early as Lowry bogeyed three straight starting at No. 2. Lowry squared the match with a par at No. 6 and a 5-footer for birdie at the seventh hole before handing McIlroy the advantage again with another bogey at No. 9.
McIlroy bogeyed the 10th hole, though, and the match was square again. Lowry matched McIlroy's birdie at the par-5 11th, chipping in from 19 feet and then went on the spurt that gave him a cushion he didn't relinquish.
Lowry acknowledged playing against someone he knew so well -- the two ate dinner together on Tuesday night -- was a factor. Had he drawn Tiger Woods, as it looked like he would before Brandt Snedeker withdrew, the task would have been more of a challenge.
"Deep down I knew I could beat him," Lowry said. "I'm not here for no reason. I'm not here to make up the numbers. I was quite nervous starting off. I handed him a few holes early doors, but he handed me a few back later on in the round. And this is match play, and I got a few breaks where I needed them, and I'm just fortunate to win."
Rd. 1: Howell def. Woods, 2 & 1
Tiger Woods played well in his opening match. But Charles Howell III played better.
As a result, Howell -- the 63rd overall seed in this event -- pulled off the upset of the No. 2 overall seed Woods, winning 2 and 1 in the looming darkness in Thursday's first round at Dove Mountain.
Howell advances to play the winner of the match between Gonzalo Fernandez-Castano and Francesco Molinari, which is all square through 15 holes and will be completed Friday.
"As far as beating Tiger Woods goes, it shows you that match play is crazy," Howell said. "I did have to play a good round but ... yeah, it's a bit hard to believe sitting here today with this."
Woods, meanwhile, leaves after a first-round loss for the second time in his last three starts. In 13 career starts in this event, Woods has failed to get out of the first round just three times, equal to the number of times he's won the title.
He played solid on Thursday, bogey free with two birdies. But Howell was also bogey-free and made four birdies. Their match was the only bogey-free match of the first round.
"It's the nature of the format," Woods said. "You've just got to beat the guy you're playing against, and I didn't do that today. Chucky won the match."
"I knew I had to play my best to have a chance out there," said Howell, who lost a match to Woods in the 1996 U.S. Amateur. "He's Tiger Woods and I was just happy to hang in there."
Woods was not happy with the outcome but was happy with the way he played. Given a chance to halt the match after 16 holes due to darkness -- both players were asked if they wanted to continue -- Woods opted to keep playing because he felt he could birdie the last two holes.
"I played well, I really did," Woods said. "I hit a lot of good shots out there."
Howell never trailed. He birdied the par-4 fifth to go 1 up, but Woods squared the match at the par-4 fifth when he rolled in a putt just inside 20 feet.
But Howell regained the lead at the par-5 eighth hole with a birdie putt of 27 feet.
Woods squared the match again at the par-5 13th with a putt from 7-1/2 feet. But Howell took the 15th and 16th holes with birdies to go 2 up. His approach at the 15th landed inside of a foot, and then he drained a birdie putt from inside 24 feet at the par-3 16th.
Howell hit 15 of 17 greens and nine of 13 fairways, while Woods hit 14 greens and 12 fairways.
Garrigus def. Grace, 4 & 3
Robert Garrigus birdied five of his first eight holes to race out to a commanding lead en route to a 4 and 3 win over Branden Grace in Thursday's first round.
Garrigus, a No. 9 seed, now faces Louis Oosthuizen in the second round of the Hogan bracket.
Garrigus opened the match by making a birdie putt from 11 feet. He added another from inside 17 feet at the third and then another from 24 feet at the fifth.
His only slip was a double bogey at the 10th but by then, it didn't matter.
Garrigus is playing in his first Accenture Match Play Championship.
Piercy def. Lawrie, 4 & 3
Scott Piercy, making his first appearance in the World Golf Championships-Accenture Match Play Championship, beat veteran Paul Lawrie of Scotland, 4 and 3, in the first round.
Piercy won the first two holes -- making eagle at the par-5 second -- and never trailed. He went 3 up at the turn with a birdie at the ninth, then produced three birdies in a four-hole stretch to end the match.
Piercy, a No. 8 seed, now plays Luke Donald in the second round of the Snead bracket.
Oosthuizen def. Ramsay, 2 and 1
It's been a week of firsts for Louis Oosthuizen, who is top-seeded in the Ben Hogan bracket.
He had never seen snow before 4 inches fell on Dove Mountain on Wednesday and halted play. And Oosthuizen was the first of the No. 1 seeds to advance on Thursday, beating Richie Ramsay 2 and 1.
Oosthuizen actually had to come from behind on the back nine to earn the victory. Ramsay was 1 up at the turn and 2 up after his opponent missed a 7-footer to save par at the 11th hole.
But Oosthuizen won the next four holes with two birdies and a par to go 2 up. He halved the 16th with a bogey -- actually missing a 6-footer for par there that would have won the match -- and the 17th with a par to seal the victory.
"Just couldn't really get going, couldn't make putts for birdies, and then had a good run from 12 to 15, taking four in a row," Oosthuizen said. "I had a little putt on 16 to win. But yeah, all in all, very happy. A bit shaky start, but I felt like I kept it together at the end."
Oosthuizen faces the big-hitting Robert Garrigus in the second round. And as for the snow?
"It was really good fun -- especially at the hotel, it was a beautiful setting last night," Oosthuizen said.
McDowell def. Harrington, 2 up
Through 11 holes, Graeme McDowell was playing steady while Padraig Harrington was missing some short putts. Consequently, the fifth-seeded McDowell was 3 up.
But McDowell then lost the next three holes, two with bogeys, to square the match. The battled between the Northern Irishman and the Irishman remained tight for the rest of the way until Harrington found trouble late to lose two of the final three holes.
McDowell said a key hole was the 15th when he followed Harrington's birdie with one of his own to keep the match squared.
"That kind of got me buzzing," McDowell said, "and I made some nice swings coming in."
McDowell advances to play Alexander Noren in the second round of the Jones bracket.
Simpson def. Lynn, 5 and 4
Webb Simpson birdied two of his first four holes on Thursday and never looked back as he beat England's David Lynn 5 and 4.
Simpson, who is playing in his second World Golf Championships-Accenture Match Play Championship, never trailed in the match and only lost one hole. He was 3 up at the turn and padded his lead with a two-putt birdie at the par-5 11th.
Simpson made a bogey at the 12th hole that allowed Lynn, who was making his debut at Dove Mountain, to briefly cut into his lead. But Simpson answered with a 4-footer for birdie at the 13th and then won with a concession after Lynn had an adventure in a fairway bunker and took four shots to reach the 14th green.
Hanson def. Bjorn, 3 and 2
Sweden's Peter Hanson, a No. 5 seed, beat 12th-seeded Thomas Bjorn of Denmark, 3 and 2, in their first-round match.
Hanson will now face Webb Simpson in the second round of the Player bracket. Not bad for someone who is battling a bulging disk and would have struggled to play had his match started on Wednesday. But an extra day of rest allowed him to get treatment and exercise.
"I was just trying to focus on putting good swings on the ball and not getting too much pain in the lower back," Hanson said.
Hanson was 2 down at the turn after a bogey at the ninth hole. But he birdied the 10th and 11th holes to square the match. He then grabbed the lead with a birdie at the par-5 13th.
Bjorn, who failed to make a birdie the entire round, suffered just his second bogey of the day at the par-4 14th to fall 2 down. Hanson then birded the next hole.
To help with his back problems, he plans to continue sleeping on a firm surface he has created in his hotel room with wood planks. Or ...
"I'll probably sleep here on the paving stones," he said.
Jacobson def. Els, 1 up
Through five holes, Fredrik Jacobson had suffered two bogeys and a double bogey and was 2 down in his first-round match to Ernie Els.
But three holes later, Jacobson had squared the match, and the 12th-seeded Swede went on to beat the No. 5 seed Els, 1 up. The Swede advances to play Marcus Fraser in the second round.
Jacobson won the seventh hole with a par and the eighth with a birdie. He then birdied the 11th and 12th holes to go 2 up, but saw Els rally back to square the match at the 15th hole.
Jacobson won the final hole with par when Els three-putted from 32 feet.
"The greens are tricky," Jacobson said. "They're a little slick sometimes. It's been a long day out there. I was just happy to come through in the end."
Fraser def. Bradley, 1 up
Marcus Fraser says he has a tendency to get down on himself. On Thursday, though, in a tight match with Keegan Bradley, the Aussie "backed" himself and came out with the upset win.
Neither player led more than 1 up during the match, and Fraser got the edge when it counted most, draining a 27-footer for birdie and a 1-up lead at the 17th hole. When he and Bradley both bogeyed the 18th hole, Fraser, who was ranked 13th in the Hogan bracket, had the surprise victory.
"I knew it was going to be obviously a tough match," Fraser said. "Keegan is a major winner and Ryder Cup player, so he's used to match play. Down the stretch he's probably one of the best in the game.
"It wasn't the prettiest match. ... But as I said before, it's match play, you can play really well and get rolled or you can play average and hang in there. And that's what I did today, hung in there and made a nice putt on 17, which really helped. ... I just backed myself. That was the difference."
Neither player played particularly well -- Fraser shot 2 over and Bradley was 4 over after holing a shot from the ninth fairway for eagle and making six bogeys. Fraser plays Fredrik Jacobson in the second round.
Noren def. D. Johnson, 6 and 4
Sweden's Alexander Noren, a 13 seed, beat fourth-seeded Dustin Johnson of the U.S., 6 and 4, in the first round.
Noren, making just his second start in this event, will now play Graeme McDowell in the second round of the Jones bracket.
After a bogey on the first hole, Noren played as well as anybody on the course Thursday. He was bogey-free for the rest of the round and posted seven birdies on his card. He was 3 up through six holes, 4 up through eight, and played even better on the back nine.
He reeled off four consecutive birdies starting at the 10th hole, making bbirdie putts of 6-1/2 feet, 9 feet, 2-1/2 feet and 4 feet.
"I played great," Noren said. "I was really happy with my game and hit a lot of greens ... It was a lot of fun."
Watney def. Toms, 5 and 4
The match didn't get off to the best of starts as Nick Watney and David Toms halved their first two holes with bogeys.
Watney got untracked with a birdie at the fourth hole, though, and never trailed on the way to a 5-and-4 victory over the 2005 champion, who had also reached the title match in 2003. Watney went on to win the eighth, 11th and 13th holes with birdies and the 12th with a par to build the 5-up lead.
"There was definitely some sloppy points for both of us, but I'm very happy to get a win," Watney said. "I have a ton of respect for DT, and it's ... always nice to get a win at this tournament. It's a world golf event, and you can't win them all if you don't win the first one, so I'm happy with the way everything went."
Watney has reached the third round each of the last three years. He'll play another former champion in Steve Stricker in Friday's second match.
"Strick is really tough," Watney said. "He's never out of a hole. He's such a great putter, and I have a tremendous amount of respect for him, too. I know it's going to be tough, and I'm excited."
Cabrera Bello def. Westwood, 19 holes
Rafael Cabrera Bello is ranked 60th in the world, 52 spots below where Lee Westwood ranks. But rankings made no difference on Thursday, as the Spaniard knocked off Westwood in 19 holes in one of the biggest upsets in the first round.
Cabrera Bello, a 15 seed, will now play Martin Kaymer in the second round of the Player bracket.
Cabrera Bello was making just his second appearance in this event, having lost in the first round last year to Jason Day. But he overcame a sluggish start to beat the second-seeded Westwood, who had reached the semifinals here last year.
"Obviously the odds were in his favor," Cabrera Bello said, "but in match play, anything can happen. I just tried my best and I was fortunate enough to win."
Westwood was 2 up through five holes, with Cabrera Bello bogeying three of those holes. But he steadied himself to play bogey-free golf the rest of the match.
He was still 3 down at the turn but he won the 10th hole with a birdie, then squared the match with pars at the 13th and 14th holes.
Westwood regained the lead with a birdie at the 15th but gave it back when he bogeyed the 18th, missing a 7-foot putt that would have clinched the win.
Cabrera Bello then won the match on the first extra hole when he rolled in a birdie putt from 10-1/2 feet.
Kaymer def. Coetzee, 2 and 1
Martin Kaymer, a No. 7 seed, said he was nervous during his first-round match against 10th-seeded George Coetzee. But the German overcame his nerves to beat the South African, 2 and 1.
Kaymer, who reached the finals here two years ago, will now play Rafael Cabrera Bello in the second round of the Player bracket.
Kaymer lost the fourth hole with a bogey and 1 down down through six. But he squared the match at the seventh hole when he stuck his approach shot to within 5 feet. He grabbed the lead with a birdie at the par-5 11th and extended it when he eagled the par-5 13th, rolling in a putt from inside nine feet after a spectacular second shot from 257 yards.
He lost the next hole with a bogey but won the decisive 17th after another great approach shot to inside two feet.
Asked why he felt nervous, Kaymer replied, "It was very strange. I never had that before, so I don't think it will stay like this. But I haven't played tournaments for two weeks and then I practiced a lot and my expectations were very high."
Furyk def. Moore, 4 and 2
Jim Furyk won four straight holes, including three with birdies, on the way to a 4 and 2 victory over Ryan Moore.
The match was all square when the two returned to Dove Mountain on Thursday to hit their second shots on the seventh hole. Moore had split the fairway while Furyk hit what he called an "ugly little low hook" into the rough when the siren blew.
"So I knew that's what would be waiting on me this morning," Furyk said. "My goal was to go out and if I could somehow manage a halve on 7, it would feel like a victory. ... I hacked it out, knocked a wedge up there from about 106 and knocked it to about four feet and made it for par, and it gave me a boost of confidence."
Then Furyk started the birdie barrage. He made a 6-footer at the par-5 eighth hole, then won No. 9 with a par and made birdie putts of 14 and 7 feet on the next two holes to take a 4-up advantage. He bogeyed the 12th hole but answered with two more winning birdies and it was only a matter of time.
"So really get being off to a really good start this morning with the halve on 7 and then winning four holes was a big jump for me," Furyk said.
He now faces Bubba Watson, who beat Chris Wood 2 and 1, in the second round.
Stricker def. Stenson, 5 and 4
Steve Stricker won the first three holes in his match against Henrik Stenson and never looked back, cruising to a 5 and 4 win in the first round.
Stricker, the 2001 Accenture Match Play champ, will now play fellow American Nick Watney in the second round of the Snead bracket.
Stricker, a No. 4 seed, had won two holes on Wednesday before play was halted, then won the third hole when the match resumed Thursday. He lost the fourth hole with a bogey -- the only hole he lost in the match -- but bounced back with a birdie at the fifth hole when he rolled in a putt from 16-1/2 feet.
After that, he steadily built his lead, withnning the seventh and 13th holes with pars. Stenson, who won this event in 2007, had just one birdie in his 14 holes played.
Clark def. Scott 2 and 1
Tim Clark won the 16th and 17th holes with pars to break open a tight match with Adam Scott and take a 2-up victory.
Scott only led twice in the match, for one hole each time, with the first advantage coming as conditions worsened on Wednesday and play was suspended. Scott made an 8-footer for birdie to sqaure the match at No. 7 and then went back to the hotel with a 1-up advantage after Clark bogeyed the par-5 eighth.
The two competitors came back out on Thursday and traded wins at Nos. 9, 10 and 11, which Clark won with a 6-foot birdie putt to square the match again. The next three holes were halved with pars and the 15th with a birdie before Clark broke away at the end.
Watson def. Wood, 2 and 1
American Bubba Watson came out sizzling on Thursday to put away pesky Englishman Chris Wood, 2 and 1, in the first round.
Watson, a No. 2 seed, will now face Jim Furyk in the second round. Watson reached the semifinals here two years ago.
The Masters champ struggled on Wednesday before a snowstorm halted play. The match was all square through six holes at that point, even though Watson had suffered a double bogey and a bogey in that stretch.
But on Thursday, he won the seventh hole with a par, then eagled the par-5 eighth when he holed out from off the green. That put him 2 up.
Watson birdied the 11th and 13th holes to match Wood, who was also playing better than he had the previous day. When Wood birdied the par-4 15th with an 11-foot putt, Watson's lead was reduced to 1 up.
But Watson won the next hole, the par-3 16th, when he rolled in an 18-footer for birdie. Both players birdied the 17th, Watson hitting his approach shot within 3 feet.
Olesen def. Donaldson, 3 and 2
In a battle of two players making their World Golf Championships-Accenture Match Play Championship debuts, Thorbjorn Olesen prevailed, beating Jamie Donaldson 3 up.
The Dane never trailed in the match and only lost three holes. Olesen struck quickly, winning the fourth, fifth and sixth holes with pars, and had an early 3-up advantage when play was suspended on Wednesday.
Donaldson came back out Thursday and won the 13th hole with a 5-foot birdie but promptly gave that back with a bogey at the next. A Donaldson par at the par-5 15th narrowed Olesen's lead to 2 up but the Dane won the match when the Welshman bogeyed No. 16.
Olesen plays Tim Clark, a 2-and-1 winner over Adam Scott, in the second round.
Rose def. Choi, 2 and 1
England's Justin Rose, a No. 2 seed, won a tight match against 15th-seeded K.J. Choi of Korea, 2 and 1, in the first round.
Rose now advances to play Belgium Nicolas Colsaerts in the second round.
Rose entered the day 2 up through nine holes but saw his lead quickly evaporate with bogeys at the 10th and 12th holes.
With the match all squared, both players birdied the par-5 13th and parred the par-4 14th. But Rose regained the advantage by converting a 23-foot birdie putt at the par-4 15th while Choi failed to roll in his 11-footer for birdie.
"I said at the beginning of the week, it comes down to that one moment in the round where you need to make something happen, and that moment for me was on 15," Rose said. "... I was looking like I was going 1 down.
"... To make a putt when I really needed it feels good, and I felt like that's what I've begun to do a lot recently."
Rose then put the match away by winning the 17th hole after Choi had trouble off the tee. He now has a chance to advance past the second round for just the second time in his eight appearances here.
Sterne def. Dufner, 1 up
South African Richard Sterne, a 14 seed, upset American Jason Dufner, a No. 3 seed, in the first round.
Sterne, advancing to the second round for the first time in three starts in this event, now faces defending champ Hunter Mahan in the Player bracket.
Sterne entered Thursday 3 up on Dufner through 10 holes. He increased his lead by winning the 11th hole when Dufner bogeyed the par-5 hole. But then Dufner got hot, reeling off four birdies in a five-hole stretch. Fortunately for Sterne, he halved two of those holes with his own birdies.
Still, when the match reached the 17th hole, Sterne was only 1 up. But Dufner found the greenside bunker with his second shot and could not take advantage of a Sterne bogey. Both players ended the match with pars.
"Match play is a strange game and it showed today," Sterne said. "I was 4 up and then suddenly I was struggling to finish the match off. That just shows you a few birdies at the right time for somebody else can put a lot of pressure on."
Henley def. Schwartzel, 1 up
Russell Henley has a new nickname: "Mr. Bracket Buster."
That's exactly what the PGA TOUR rookie did to many fantasy golf fans when he upset Charl Schwartzel 1 up in the first round.
"I've heard a lot of comments from people saying they expected him to win, and that gave me a little motivation for sure," Henley acknowledged. "But he's an outstanding player, obviously. Can't really not be a great player when you win the Masters."
Henley, who won his first start as a PGA TOUR member earlier this year in Hawaii, shook off a disappointing double bogey-bogey finish on Wednesday that eliminated his 2-up advantage. He came out Thursday and won the 12th hole with a par and the 13th with a birdie to regain that edge, then reeled off five straight pars to win the match.
"I tried not to get too up or down," Henley said. "TRhat was one of the biggest things mentally, just hang tough with an even keel. That's something I've worked on this whole year."
Mahan def. Manassero, 5 and 4
Hunter Mahan opened defense of his World Golf Championships-Accenture Match Play Championship crown by knocking off Italian teen Matteo Manassero, 5 and 4, in the first round.
Mahan now faces South African Richard Sterne in the second round of the Player bracket.
Mahan, a sixth seed, handed Manassero, an 11th seed, his first first-round loss in three career appearances in this event. Mahan was 4 up through nine holes before play was halted on Wednesday. He opened Thursday with bogeys on his first two holes, with Manassero winning the 11th hole with a par.
But Manassero could never find his game. In the 14 holes he played, Manassero suffered eight bogeys while failing to record a birdie. Mahan, meanwhile, had just one birdie but was still happy with his play.
"I felt like I let some holes kind of slip away that I should have done better on," Mahan said. "But all in all, I feel good about how I played and how I'm swinging. I've just got to keep it up."
Mahan has now won nine of his last 10 matches in this event.
Colsaerts def. Haas, 5 and 4
Nicolas Colsaerts of Belgium, a 10th seed, defeated American Bill Haas, a seventh seed, 5 and 4, in their first-round match.
Colsaerts advances to play the Justin Rose-K.J. Choi winner in the second round of the Hogan bracket.
Colsaerts entered the day 3 up through eight holes. He parred all six of his holes Thursday. Meanwhile, Haas bogeyed the par-5 11th when he was forced to take a penalty stroke after an errant tee shot, then bogeyed the par-4 14th after a poor approach shot left him in the native area.
Colsaerts is making just his second appearance in this event. He lost in the first round last year.
Garcia def. Jaidee, 20 holes
Sergio Garcia appeared poised to put Thongchai Jaidee away when he returned to the 16th green on Thursday to attempt an 11-footer for birdie and the win.
Garcia missed the putt, though, as well as the 7-footer on the return and suddenly his 2-up lead was just 1. Jaidee then squared the proceedings on the 18th hole with a 4-footer for birdie to send the first match of the week into overtime.
The two halved the first extra hole with pars. Garcia ended up putting the match away when he two-putted for birdie from 31 feet at the par-5 second, making his 3-footer after Jaidee missed from 14.
Garcia plays Matt Kuchar in Friday's second round.
Poulter def. Gallacher, 2 and 1
Englishman Ian Poulter, a No. 3 seed, defeated 14th-seeded Stephen Gallacher of Scotland, 2 and 1, in the completion Thursday of their first-round match.
Poulter now faces American Bo Van Pelt in the second round Friday of the Snead bracket.
Poulter entered the day 3 up through 12 holes. He stumbled at the par-4 14th, losing the hole with a double bogey. But after Gallacher drained a 20-foot birdie putt at the 15th, Poulter followed with his own short birdie putt after hitting his approach shot inside 4 feet to halve the hole and derail Gallacher's momentum.
For Poulter, it was the first time he had advanced past the first round since winning here in 2010.
Day def. Z. Johnson 6 and 5
Jason Day did most of the heavy lifting on Wednesday as he bolted to a 6-up lead through his first 10 holes.
Zach Johnson did manage to cut into the Aussie's lead briefly when play resumed on Thursday, sinking a 5-footer for birdie at the 11th hole to get to 5 down. But Day finished the former Masters champ off with 2-foot birdie putt on the next par 5 after Johnson missed from 15 feet.
Day, who shot 5 under and didn't drop a shot to par, will play the winner of the match between Charl Schwartzel and Russell Henley.
Kuchar def. Fujita, 3 and 2
Matt Kuchar left the Ritz-Carlton Golf Club at Dove Mountain with a comfortable 3-up advantage through over Hiroyuki Fujita when play was called on Wednesday afternoon. A pair of routine pars at the 15th and 16th holes were good enough for the victory on Thursday.
Kuchar, who shot 1 under, atually had a chance to end things earlier but he missed an 11-footer for birdie to go 4 up at the 15th hole. He will play the winner of the match between Sergio Garcia and Thongchai Jaidee.
Van Pelt def. Senden, 6 and 5
American Bo Van Pelt, a sixth seed, defeated 11th-seeded John Senden of Australia, 6 and 5, in the first round.
Van Pelt now takes on Ian Poulter in the second round.
Van Pelt needed just one hole after Thursday's restart to end his match. He won the par-5 13th with a par, as Senden bogeyed the hole after an errant tee shot left him scrambling from the native area.
Senden did not record a birdie while suffering five bogeys on his card. He was 1 up through six holes but lost the last seven holes.
