Dustin Johnson and Jon Rahm share the lead after the first round of the PGA Tour Championship, but Rory McIlroy is lurking after a strong start.
Johnson, the FedEx Cup leader ahead of the season-ending event, carded a 3-under 67 at East Lake in Atlanta on Friday.
The American started the tournament atop the leaderboard at 10 under, but his lead is already gone. Johnson is joined at 13 under by Rahm, who opened with a 65 just days after his incredible win at the BMW Championship. Rahm beat Johnson in a thrilling playoff at Olympia Fields Country Club. The stars now are in place to battle for the $15 million first prize.

Johnson was even through 11 holes before making birdies at 12, 13 and 15. Rahm also found form on the back nine with four birdies in five holes beginning at 12.
Justin Thomas, third when the event started, is still there after a 4-under 66, and still two strokes back.
McIlroy, the defending FedEx Cup champion, produced the equal best round of the day to charge into contention. The Northern Irishman fired a 6-under 64 that included three straight birdies to finish as he moved into 9 under for the tournament.
McIlroy came from fifth in the overall standings to win the Tour Championship and FedEx Cup last year.
The other player to shoot 64 was Abraham Ancer, who climbed into 7 under and outright fifth place.
Xander Schauffele (67), the runner-up to McIlroy last year, is tied for sixth at 6 under, alongside Brendon Todd (67), Im Sungjae (68) and Webb Simpson (70).
Marc Leishman (66), Tyrrell Hatton (67), Lanto Griffin (67) and Daniel Berger (69) are a shot further back.
PGA Championship winner Collin Morikawa fell back into a tie for 14th after a 71. Bryson DeChambeau is tied for 18th after his 72.
