American Xander Schauffele has won the Travelers Championship by two shots in Connecticut.
Schauffele, who led going into the final round, birdied the 18th for a two-under-par 68 to finish on 19 under.
Sahith Theegala had taken the lead on the 17th but saw his challenge falter on the final hole as he finished with a double bogey to sit tied for second.
US amateur Michael Thorbjornsen fired a second consecutive 66 to finish in fourth place on 15 under.
“It’s incredible,” world number 15 Schauffele, 28, said. “I was looking at birdie just getting into a playoff. I saw a little hiccup for Sahith and I knew I had to get it into the cup.”
World number one Scottie Scheffler finished on 10 under alongside Scotland’s Martin Laird, while world number two Rory McIlroy, who was joint-leader after the first round, shot a 67 to finish on nine under
