Won his first major title in the 2020 U.S. Open at Winged Foot, posting a closing 67 – the best round of the day by three – to turn a two-stroke deficit into a six-shot victory.
Easily recognised by his Ben Hogan-style caps and the fact his clubs are all the same length, DeChambeau bulked himself up during the coronavirus lockdown, prompting much talk about his increased length off the tee, but his short game was much-improved too and that showed again in March when he pipped Lee Westwood to the Arnold Palmer Invitational.
He first came to global attention in 2014 at the World Amateur Team Championship, where his 11-birdie 61 in the third round was a tournament record.
DeChambeau then joined Jack Nicklaus, Phil Mickelson, Tiger Woods and Ryan Moore as the only men to win the American college title and US Amateur Championship. He was also unbeaten in the Walker Cup at Royal Lytham in 2015 and tied for second at the Australian Masters.
The top amateur in coming joint 21st at the 2016 Masters, he then turned professional. Two years later he captured the first two legs of the FedEx Cup play-offs and was a wildcard pick for the Ryder Cup in Paris.
Other successes include a seven-shot win in the 2019 Dubai Desert Classic.
