MEDINAH, Ill. — Winless over the last 12 months, Justin Thomas knew he was playing well and he was due for a low round.

Saturday at the BMW Championship was more than he might have imagined.

Thomas smashed the course record at Medinah with an 11-under 61 that gave him a six-shot lead over Patrick Cantlay and Tony Finau.

He opened with five birdies, and none was worthy of a highlight reel because of what followed. He hit a 5-wood from 260 yards on the par-5 10th that was so pure he twirled his club and watched it roll out to 2 feet.

“It was easy to get pretty wrapped up in the emotions and get the adrenaline going and I had to take a little bit off that 9-iron,” Thomas said. “If I’m trying to be perfect there and I don’t hit it right, that very easily could go in the water.”

Thomas was at 21-under 195, with Finau (68) and Cantlay (67) chasing him.
