Xander Schauffele had a 6-under 64 for the best opening round at East Lake by two shots. It was only worth a share of the lead Thursday in a Tour Championship where 30 players were given a head start based on their position in the FedEx Cup.
Justin Thomas, who started at 10-under par and a two-shot lead as the No. 1 seed in the FedEx Cup, hit pitching wedge into the water for double bogey and twice missed 3-foot putts in his round of 70. Instead of being six shots behind, he goes into the second round tied.
Brooks Koepka birdied three of his last four holes for a 67 and joined them at 10-under par.
The score to par is all that matters in deciding who wins the FedEx Cup and the $15 million prize.
