Jason Day and Jordan Spieth have been the two best players this season, and they'll have one more chance to go toe-to-toe at the Tour Championship. Here are four featured first-round pairings that you should keep an eye on as the FedEx Cup is decided at East Lake Golf Club (all times ET) Click here for full tee times:
Brooks Koepka, Bill Haas: Noon Thursday
Brooks Keopka has had a miserable FedEx Cup Playoffs, with two missed cuts and T-49 in the no-cut BMW. But, with Jim Furyk missing the Tour Championship because of a wrist injury and his Presidents Cup spot in doubt, a strong showing this week could help sway U.S. captain Jay Haas in Koepka's direction should a replacement be needed. And, he's playing the first round alongside captain's pick and captain's son, Bill.
Rory McIlroy, Justin Rose: 1:10 p.m. Thursday
There are only four Europeans in this week's 30-man field, but two of them will be paired together in the opening round. McIlroy has largely been overshadowed by Day and Spieth since his return from an ankle injury, but he did finish T-4 last week outside Chicago to help boost his chances for the season-long prize. Rose, meanwhile, shot a second-round 64 en route to a T-13 finish at the BMW and now heads to a course where he has finished sixth or better each of the last three years.
Rickie Fowler, Henrik Stenson: 1:50 p.m. Thursday
After dueling earlier this month at TPC Boston, Fowler and Stenson will again play together during the opening round in Atlanta. Fowler's Deutsche Bank win gives him a slight edge over Stenson in the standings, but both men control their own destiny and will win the FedEx Cup with a win this week. It's a path that Stenson is quite familiar with, as the Swede took home both the Tour Championship and FedEx Cup titles just two years ago.
Jason Day, Jordan Spieth: 2 p.m. Thursday
Day and Spieth have been 1-2 in the standings the entire postseason, and as a result they are playing together in the opening round for the fourth consecutive event. While Spieth has been the player to watch most of the summer, it is now Day's turn in the spotlight as the Aussie enters as the new world No. 1 and fresh off a dominating victory at Conway Farms, his fourth win in his last six starts. Both players have the most favorable path to the FedEx Cup, and should Day claim the title, it could make the Player of the Year debate rather interesting.
