Argentina, Scotland, Sweden and Germany all held the outright lead at some point Sunday, yet never managed to build a significant cushion -- and the top positions on the leaderboard flip-flopped all day.

Scotland went up at the par-3 11th, when Warren got his tee shot within 10 feet and Montgomerie made the putt to put his team at 16 under, one shot clear of Germany and Argentina. But the Scots strung together seven straight pars from there, and things soon were knotted again.

Siem's 25-foot birdie at the par-3 16th gave the Germans their first lead, which they immediately gave back with a bogey -- their lone mistake -- at the par-4 17th. And Sweden used consecutive birdies at Nos. 12 and 13 to match the Germans and Scots at 16 under, then faltered at the final hole.

"It's always disappointing when you finish like that when you're in the hunt," Petterson said. "We had a chance and we had a good time."

Heavy rain began falling early in the day, stopped briefly as some of the final pairings teed off, then began pouring again with most teams still on the front nine, prompting a suspension that lasted 1 hour, 43 minutes.

Players were held on the course for about a half-hour before being brought into the clubhouse, as crews used squeegees to remove standing water from some fairways and greens. Strong winds ripped at least one umbrella to shreds, while turning others inward -- their frames unable to withstand the 45 mph gusts.
