Justin Thomas claimed a one-stroke victory at The Players Championship after a run of three birdies and an eagle across four holes unseated overnight leader Lee Westwood on Sunday.
World number three and American star Thomas – fuelled by a four-under-par 64 – headed into the final round at TPC Sawgrass three strokes adrift of Westwood.
Westwood (72) had finished second at last week's Arnold Palmer Invitational, trailing Bryson DeChambeau (71), who was his nearest competitor again at the end of Saturday's play.
Westwood would be a runner-up once more, but this time was bested by Thomas, who stormed into the lead thanks to a frantic spell.
Westwood lacked momentum throughout his round and was back at 12 under – one over for the day – at the turn when Thomas took flight.
Thomas bogeyed the eighth but responded with a birdie at the ninth and suddenly found form.
He made three at the par-four 10th and then, with the day's decisive putt, claimed the lead outright with an eagle from 19 feet at 11. Another birdie at the next hole secured breathing space.
Although Westwood recovered to end the day as he started it, at 13 under, there was only a brief Thomas wobble with bogey at 14 followed by birdie at 16.
Thomas, who has a single major title at the 2017 US PGA Championship, claimed a maiden triumph at The Players and returned to the winner's circle for the first time since August's WGC-FedEx St. Jude Invitational.
It is also Thomas' 14th PGA Tour triumph, becoming the fourth player since 1960 to win 14 times on Tour before turning 28 – joining Tiger Woods, Jack Nicklaus and Johnny Miller.
"I fought so hard today," said Thomas, who tied the lowest final 36-hole score in Players history with his 64-68 (132) over the weekend. "I stayed patient. It was probably one of the best rounds of my life, tee to green."
Brian Harman used a final-round 69 to finish tied for third alongside U.S. Open champion DeChambeau – two shots behind Thomas.
Five-time major champion Phil Mickelson (71) and Jason Day (73) were among the players to end the tournament 35th in the standings, 11 shots off the pace.
Dustin Johnson (71) – the world number one – climbed up into a tie for 48th at one under, a stroke better off than Jordan Spieth (75), who is still without a win since 2017.
