The Americans will hold the advantage by the end of the Ryder Cup on Sunday afternoon, and for good reason.
The U.S. team went on a tear in the Saturday morning foursomes, led by Phil Mickelson and Keegan Bradley's disposing of usual stalwarts Lee Westwood and Luke Donald 7 & 6. They will look to close the deal by winning at least half of the singles matchups on the Ryder Cup's final day.
Which U.S. golfers will come through for their team on the last day? Many times, it's the golfers who have been dominating the course all weekend.
That's where we'll start when looking at the hottest golfers during this tournament.
The Ryder Cup rookie's excitement during this entire tournament has been contagious, and it's been well warranted.
Bradley and Mickelson have been the most dominant pair this weekend and the most fun to watch. No golfer has detracted the eyes away from Tiger and Rory more than the emphatic Bradley. He's done it not just with antics, but with his play as well.
Credit Lefty just as much for his foursome success this weekend. Mickelson has somehow figured out how to win in this format, playing undefeated golf all weekend.
His putter was even more impressive than advertised, contributing to five birdies in the morning as opposed to one from Donald and Westwood. Always in the mix in the single, Mickelson is one of the best American bets to keep up the pace.
For a quiet guy, Jason Dufner's play has been louder than ever at Medinah. Another Ryder Cup rookie has made his mark on the world stage, carrying Zach Johnson to a foursome victory in the morning. Their round was full of pars, but let their opponents Nicholas Colsaerts and Sergio Garcia make mistakes and fall behind.
If he can keep his putting on board in single matchup play, Dufner can go from unsung hero to Ryder Cup legend.
The U.S. Open champion has shown why he's a major winner with some memorable shots, specifically in best ball competition. The afternoon demon has five birdies in that competition.
Simpson has one of the highest ceilings of all American golfers in match-play singles. Once the clock passes noon, his chances are even better.
