Watson overcame a six-stroke deficit Sunday to win his third Travelers Championship title, shooting a 7-under 63 for a three-stroke victory.
The left-hander became the first three-time winner on the PGA Tour this season and pulled within one of Billy Casper’s tournament record of four victories.
He finished at 17-under 263. Third-round leader Paul Casey, Stewart Cink, Beau Hossler and J.B. Holmes tied for second. Casey shot 72, Cink 62, Hossler 66 and Holmes 67.
Watson also came from six back to win the 2010 event for his first tour title and beat Casey in a playoff in 2015.
