SAN ANTONIO (AP) -- Kevin Chappell made an 8-foot putt on the final hole to win the Valero Texas Open by one stroke on Sunday.
Chappell had a 4-under 68 in the final round to finish at 12 under for the tournament, edging Brooks Koepka at TPC San Antonio to earn his first PGA Tour victory in his 180th career start.
Koepka, a member of the U.S. Ryder Cup team last year, was looking for his second PGA Tour win. He had the best round of the day at 7-under 65. Before Chappell came down the 18th hole, Koepka had birdied the hole with a 3-foot putt to tie him.
Second-round co-leader Tony Finau got in a position to tie Koepka when he birdied four of five holes on the back nine. But his par-bogey finish left him to settle for a final-round 69 and a third-place tie with Kevin Tway (69) at 9-under.
Australian Aaron Baddeley fired 68 to finish fourth at 8 under.
