World No 1 Scottie Scheffler hit a five-under 67 on Sunday to claim a 19th PGA Tour victory at the Procore Championship in Napa, California.
The American was neck-and-neck with US Ryder Cup team-mate Ben Griffin for much of the final round, splitting six birdies with one bogey to finish his tournament on 19 under.
Scheffler's score proved to be just enough for a sixth PGA Tour win of the year when Griffin three-putted the par-five 18th to finish one shot back.
Reflecting on a tournament in which he seemed to get better as play went on having been eight shots back on Griffin at the end of the second round, Scheffler said: "I knew I was going to have to have another really good day. I was chasing down some pretty talented guys on the leaderboard.
"Fortunate to be the winner this week."
