All times are eastern.

Marc Turnesa, Chris DiMarco
Tee time: 3:45 p.m.
Tee: No. 1
Total TOUR wins: 3
Why you should watch: For the second time in the Fall Series, Turnesa enters the final round with the lead. He didn't falter at the Viking Classic -- he lost in a playoff to Will MacKenzie -- but the rookie has bigger problems on Sunday. Turnesa is facing an army of players within a few shots, and any of them can drop a 62 at a moment's notice. Turnesa must shoot better than the 69 he produced on Saturday to win for the first time.

Michael Allen, Ken Duke
Tee time: 3:35 p.m.
Tee: No. 1
Total TOUR wins: 0
Why you should watch: Allen shot a 64 on Saturday and sits only one shot off the lead. The 64 was the absolute highest score he could have shot; he missed a six-foot eagle putt on No. 16, and he was five-under after only four holes. Allen, 49, has never won on TOUR and doesn't have a card locked up for 2009. Duke is probably the wild card on the board. Duke is a hardened veteran of the professional golf wars and usually avoids big numbers on his scorecard. The key stat? In 2005, Duke was ranked 556th in the world. Now? He's 81st.

Chris Stroud, Zach Johnson
Tee time: 3:25 p.m.
Tee: No. 1
Total TOUR wins: 4
Why you should watch: Stroud, who finished sixth last week in the Valero Texas Open, doesn't have his card locked up for 2009, and he needs a win on Sunday close it out. Stroud has struck the ball perfectly all week -- he is second in Greens in Regulation -- but his putting has held him back. He will have to putt lights-out in order to have a chance on Sunday.
