The 31-year-old Canadian was the winner in 2019, where he emerged victorious over Charley Hoffman by two-shots.

It was a clinical display on Sunday from the former champion, shooting a closing four-under 68 at TPC San Antonio' to finish at 15-under for the tournament, enough to secure his second PGA Tour win.

He now heads to the Masters, where he tied sixth last year for his second straight top-10 finish at Augusta National.

"I had been feeling really good about my game, and looking forward to getting back here to San Antonio," Conners said.

"When I won in 2019, it was different, a real roller-coaster final round. I dug deep on the back nine, so I tried to channel that part of it today."

A shot behind Patrick Rodgers starting play, Conners shot to a three-shot lead after he birdied No.15. Stevens eagled the 17th, but missed a birdie putt at 18 that would have sent him to 15-under. Connors cleaned up a short putt for par on 18, which was all he needed to claim the title.

Stevens finished with a classy 66 to finish at 14-under-par, Sam Ryder (66) and Matt Kuchar (68) followed at 13-under.

Rodgers saw a chance for his first Tour victory and first Masters spot slip away. He shot a 73 to finish fifth at 11-under.

Conner's best finish since hoisting the 2019 Texas Open trophy was a third-place effort at the Arnold Palmer Invitational last year.

Neither Cam Davis nor Harrison Endycott made the cut in Texas.
