Phil Mickelson ended the longest drought of his career with a playoff victory Sunday over Justin Thomas in the Mexico Championship, capping off a final round that included Thomas holing a wedge for eagle on the final hole of regulation.
Mickelson, who closed with a 5-under-par 66, won for the first time since the 2013 British Open at Muirfield, a stretch of 101 tournaments.
‘‘I can’t put into words how much this means to me,’’ Mickelson said. ‘‘I knew it was going to be soon — I've been playing too well for it not to be. But you just never know until it happens.’’
Thomas was coming off a playoff victory at the Honda Classic last week, and he delivered the biggest moment at Chapultepec Golf Club in Mexico City. Tied for the lead, his shot to the 18th from 119 yards landed in front of the pin and spun back into the hole for an eagle and a 64.
It almost was too good to be true. Thomas, who said Thursday he had never felt worse over the ball, had a 62-64 weekend and suddenly, at at 16-under 268, had a two-shot lead.
Mickelson, who turns 48 in June, responded with a two-putt birdie on the par-5 15th and a 20-foot birdie putt on the 16th to tie Thomas.
Tyrrell Hatton, playing in the final group with Mickelson, was stride for stride. He capped off a 3-3-3-3 stretch on the back nine with an eagle at the 15th. But on the final hole, Hatton missed the green to the right, chipped 10 feet by, and missed the par putt for a 67 to fall out of a playoff.
The sudden-death playoff — the sixth in eight PGA Tour events this year — didn’t last long.
Thomas went long on the par-3 17th hole and chipped to just inside 10 feet. Mickelson’s 18-foot birdie putt for the victory swirled around the cup.
Thomas, however, never got his par attempt on the right line.
Shubhankar Sharma, the 21-year-old from India who started with a two-shot lead, didn’t make his first birdie until the 12th hole. He finished with consecutive bogeys for a 74, six shots behind in a three-way tie for ninth.
Hatton tied for third with Rafa Cabrera Bello, who holed a bunker shot for eagle on the opening hole and was among six players who had at least a share of the lead.
LPGA — Michelle Wie holed a 36-foot putt from off the green on the final hole to win the Women’s World Championship by one stroke in Singapore, capturing her first LPGA tournament since the 2014 US Women’s Open.
With four players in contention to win on the last hole, Wie managed to separate herself from the pack when she drained her lengthy birdie putt on the 72nd hole for a final round of 7-under 65 to finish at 17-under 271.
The 28-year-old Wie, who led the tournament after three rounds a year ago before fading, leaped into the air and clenched her fist in celebration as the ball disappeared into the bottom of the cup.
‘‘Winning is everything. I mean, there is no better feeling than when you think you sink that winning putt. It’s a high, for sure,’’ Wie said.
Third-round leader Nelly Korda parred her last eight holes in a row. The 19-year-old, who only joined the tour last year, hit a superb approach into the 18th to set up a birdie opportunity that would have forced a playoff but missed her 8-foot putt and settled for a final-round 71.
‘‘I had a bunch of putts that were really close and a lot of them lipped and burned edges. It definitely hurts, but that’s golf,’’ Korda said.
Danielle Kang, last year’s Singapore winner, parred her last 14 holes and was unable to drain a longer birdie putt on the last to miss out on a playoff as she closed with a 70. Korda and Kang finished in a four-way tie for second at 16 under, alongside Jenny Shin (65) and Brooke Henderson (67).
European — George Coetzee closed with a 4-under 67 for a two-shot victory over Sam Horsfield in the Tshwane Open in Pretoria, South Africa.
It was the South African golfer’s first victory in two years.
Champions — Steve Stricker birdied the par-5 15th and closed with three pars for a 4-under 69 to win the Cologuard Classic, his first Champions event.
The 12-time PGA Tour winner finished two strokes ahead of Jerry Kelly (65), Gene Sauers (70), and Scott Dunlap (71). Stricker won in his eighth start on the 50-and-over tour.
