Justin Thomas carded an impressive seven-under 65 to take a share of the lead after the opening round of the BMW Championship on Thursday.
The 2017 US PGA Championship winner is atop the leaderboard alongside fellow American Jason Kokrak at Medinah Country Club, where the pair equalled the course record.
Thomas finished his day with seven birdies and no bogeys, while Kokrak dropped just one shot but added an eagle to finish his day in a tie for the lead.
A wrist injury saw Thomas struggle earlier this season, including missing the cut at the U.S. Open.
But he has been good as of late as he finished tied for 11th at The Open and in the top 12 or better in each of his past four tournaments.
"It's weird," he said, via the Golf Channel. "Yeah, I mean, it's been an odd season just because I've missed three tournaments. But the difference with this season and any other season is I'd won.
"I'm playing every bit as good as I have any other year this year, for sure."
Thomas is sitting pretty in getting to the Tour Championship at East Lake next week, starting 15th in the FedEx Cup standings and now projected to be top.
Kokrak needs a good performance after starting 32nd – with the top 30 progressing – and is now projected to be third.
A shot back of the leaders is a group of five – Jim Furyk, Joel Dahmen, Lucas Glover, Brandt Snedeker and Patrick Cantlay.
World number one Brooks Koepka, Justin Rose and Jon Rahm all opened with four-under 68s, a shot better than Rory McIlroy.
Jordan Spieth and Tiger Woods need to climb the leaderboard to reach the Tour Championship.
Spieth carded a two-under 70, while Woods opened with a 71, the duo projected to be outside the top 30 in the FedEx Cup as things stand.
