Phil Mickelson eclipsed a moment of magic from Justin Thomas to beat his compatriot in a play-off at the WGC–Mexico Championship and secure his first title since winning the Open in 2013.
The American pair finished tied on 16 under par after an enthralling final round at Chapultepec Golf Club.
Mickelson saw his birdie putt lip out at the first play-off hole – the par three 17th – but when Thomas failed to get down in two from behind the green the 47 year old had his first victory in almost five years.
Tyrrell Hatton, who missed out on extra holes after a bogey at the last, and Spain’s Rafa Cabrera Bello tied for third on 15 under.
Cabrera Bello had made the first move on Sunday when he chipped in from a bunker for eagle at the first to catch overnight leader Shubhankar Sharma before the Indian had even teed off. The Spaniard, Hatton and Mickelson all had spells in front, but Thomas, who was 11 shots behind halfway leader Sharma on Friday night before carding a blistering 62 on Saturday, made six birdies in his first 15 holes to edge ahead.
A bogey on the 17th looked to have derailed his challenge, but Thomas spun his 120-yard approach back into the cup at the 18th to set a daunting clubhouse target with a round of 64.
Hatton joined him when he followed a birdie on the 14th with an eagle from 11 feet on the 15th, while Mickelson birdied the 15th and 16th, before his 25-foot effort on the next missed by a whisker.
With both needing a birdie on the last, Hatton and Mickelson miscued their approaches and the former was unable to get up and down, but the five-time Major winner held his nerve from five feet to seal a closing 66, before a par at the par-three 17th hole saw him become the oldest winner of a World Golf Championships event.
Mickelson said: “I can’t put into words how much this means to me, it’s been a long time. To come here to Mexico City, and play against the best players in the world, and finally come through is so satisfying. I knew it was going to come soon, I was playing too well for it not to, but you never know until it happens. My game is starting to get to a level that is some of my best golf and it seems like it’s just in time. It’s nice to be in that small circle called the winner’s circle; I haven’t been in it for a while.”
Thomas, who had won at the previous week’s Honda Classic, said: “I’m definitely disappointed, but there’s nothing for me to hang my head about. To even have a chance to win this tournament after where I was through 36 holes, I’m very proud of myself. I think it’s the most maturity and I’ve shown in a tournament I’ve ever played.”
Hatton, who finished 10th in this event last year, said: “It just felt like I was pretty unlucky out there today. On six I hit a really poor drive, and ended up right up against the tree. I felt like I got unlucky on 11 as well; I didn’t hit a bad shot there, but walked off with a six. It just wasn’t my day today.”
