The biennial Ryder Cup tournament, which is being hosted at the Medinah Country Club outside of Chicago, is entering the final round.
Unlike the events on Friday and Saturday, which required golfers to pair up and work as a team, Sunday's final round will force the golfers to go solo and face their opponent man-to-man.
There are 12 singles matches, so even though Europe is trailing USA 10-6, there are still 12 points to be had, giving Europe more than enough time to catch up.
The USA is not faced with the pressure of pulling off a comeback, as their four-point lead could allow them to cruise to a carefree victory.
As long as the U.S. golfers don't have a total meltdown, they seem to be in good shape.
But even so, the singles round will feature multiple head-to-head matches worth watching, regardless of the team score.
If you're not sure who to follow, here are five singles matchups worth keeping an eye on.
Ian Poulter (EUR) vs. Webb Simpson (USA)
After going 3-0 in his Ryder Cup matches the first two days, Ian Poulter has been one of the few bright spots for Team Europe.
It's fair to say that Poulter is the only reason Europe even has a chance as the tournament enters the final round.
During the Saturday afternoon four-ball competition, Poulter teamed up with Rory McIlroy and defeated Jason Dufner and Zach Johnson.
Poulter will play his singles round against Webb Simpson, who Poulter already was able to defeat in the Saturday morning foursomes.
Tee Time: 12:14 pm ET
Rory McIlroy (EUR) vs. Keegan Bradley (USA)
Thanks to his recent success, Rory McIlroy is one of the most talked-about golfers in the sport.
McIlroy is only 2-for-4 in this Ryder Cup, so he hasn't been a key difference-maker, but he's still an exciting golfer.
McIlroy will play his singles round against Keegan Bradley.
Tee Time: 12:25 pm ET
Graeme McDowell (EUR) vs. Zach Johnson (USA)
Zach Johnson has been one of the key contributors for Team USA.
Johnson was able to win his first two events, but he suffered a loss during Saturday afternoon's four-ball event against Rory McIlroy and the red-hot Ian Poulter.
Johnson will be asked to produce another point in his singles matchup against Graeme McDowell.
The singles round will be the first time McDowell and Johnson have faced each other in this tournament.
Tee Time: 1:09 pm ET
Phil Mickelson (USA) vs. Justin Rose (EUR)
Phil Mickelson participated in the first three events of the tournament and has been on the winning side each time.
Mickelson sat out of Saturday afternoon's four-ball round, so he was unable to contribute. But the three points he has already produced have been huge for USA.
On top of Mickelson having a very solid tournament, he is also one of the most well-known and exciting golfers around.
In the final round, Mickelson will take on Justin Rose, who is 2-1 in this Ryder Cup.
Tee Time: 12:36 pm ET
Tiger Woods (USA) vs. Francesco Molinari (EUR)
Tiger Woods has been a bit of a disappointment in this Ryder Cup, having lost all three of his events.
However, he was able to sink three birdies of the final five holes Saturday afternoon, so there's a chance he's coming to life.
Not to mention, it's Tiger Woods. He's the most entertaining and headline-worthy golfer in the world.
Woods will tee off against Francesco Molinari.
Tee Time: 2:04 pm ET
