Billy Horschel was in control for most the day, but Rory McIlroy caught him on the back nine to draw even heading into Sunday's finale at East Lake. Here's the lowdown from Saturday's action at the Tour Championship.
Leaderboard: Rory McIlroy (-9), Billy Horschel (-9), Jim Furyk (-7), Rickie Fowler (-6), Justin Rose (-6), Jason Day (-6)
What it means: McIlroy and Horschel will have more than just a Tour Championship trophy on the line in the final round. If either player wins, they will also take home the $10 million FedEx Cup bonus. Horschel started the back nine with a three-shot lead, but he had trouble finding the fairway and made bogeys at 10 and 13, and McIlroy tied him with an eagle at the par-5 15th.
Round of the day: Gary Woodland shot the lowest round of the week so far with a bogey-free 63. He made five birdies on the front nine to turn in 30, and he holed out from a greenside bunker on the par-5 15th. Another low round on Sunday, and Woodland will have a good chance of qualifying for the WGC-HSBC Champions event in China.
Best of the rest: World No. 2 Adam Scott moved into the top 10 with a 5-under 65. Scott made seven birdies and two bogeys, and he hasn't finished higher than T-16 in his last nine events.
Biggest disappointment: Jordan Spieth shot a puzzling 10-over 80, which included five straight bogeys to start the back nine. For the round he made 10 bogeys, a double bogey and two birdies. Yikes.
Main storyline heading into Sunday: All eyes will be on the final group as McIlroy and Horschel are paired together for the second straight day. McIlroy can cap off an incredible season that's already included two majors, a WGC event and a win at the European Tour's flagship event. Horschel will also have a chance to win back-to-back tournaments and take home the $10 million bonus. Furyk, who hasn't won since the 2010 Tour Championship, can also get a much-needed win after several close calls this season.
