Bryson James Aldrich DeChambeau (born September 16, 1993) is an American professional golfer who plays on the LIV Golf League.

[7] DeChambeau wore an anachronistic flat cap while on the golf course due to his admiration for Ben Hogan and fellow SMU alumnus Payne Stewart.

Amateur titles in the same year, joining Jack Nicklaus (1961), Phil Mickelson (1990), Tiger Woods (1996), and Ryan Moore (2004).

[3] DeChambeau made his PGA Tour debut as an amateur in June 2015 at the FedEx St. Jude Classic near Memphis, Tennessee, and finished in 45th place.

[13] At the 2015 Australian Masters in November, DeChambeau was runner-up with John Senden and Andrew Evans, two shots behind the winner Peter Senior.

[15] Immediately after the Masters in mid-April 2016, DeChambeau turned professional and signed a long-term agreement with Cobra-Puma Golf.

[20][21] On July 16, 2017, DeChambeau earned his first PGA Tour victory by winning the John Deere Classic by a single stroke over Patrick Rodgers.

The win, coming the week before, gained DeChambeau a place in the 2017 Open Championship, where he missed the cut after rounds of 76–77 (+13).

[22] On June 3, 2018, DeChambeau won the Memorial Tournament in Dublin, Ohio, in a sudden-death playoff against Kyle Stanley and An Byeong-hun, after the three finished regulation play tied at −15.

[24] The following week, DeChambeau won at the Dell Technologies Championship played at TPC Boston in Norton, Massachusetts, with a final score of −16, two shots clear of Justin Rose.

[26] In September 2018, DeChambeau was named as a captain's pick by Jim Furyk for the United States team participating in the 2018 Ryder Cup.

DeChambeau claimed his maiden European Tour title by producing a closing 64 to win the tournament by seven shots.

[29] In December 2019, DeChambeau played on the U.S. team at the 2019 Presidents Cup at Royal Melbourne Golf Club in Australia.

[30] Beginning in late 2019, DeChambeau set out to add muscle mass in order to increase his swing speed and hit the ball farther.

[31] On July 5, 2020, DeChambeau won the Rocket Mortgage Classic in Detroit, Michigan, by three strokes over Matthew Wolff.

[34][35] In his next start two weeks later at the WGC-FedEx St. Jude Invitational, DeChambeau's tee shot at the 7th stopped near the base of a tree.

[35] Brooks Koepka later poked fun at DeChambeau, faking as though he was summoning a rules official in response to an ant infestation after he hit his drive into a similar position during the same tournament.

The win moved him to number five in the Official World Golf Ranking, matching his previous best, which he had first achieved in November 2018.

[38] In March 2021, DeChambeau won the Arnold Palmer Invitational at Bay Hill Club & Lodge in Orlando, Florida.

That comment drew the ire of Ben Schomin, a tour operations manager for Cobra Golf who caddied for DeChambeau at the Rocket Mortgage Classic two weeks prior.

[40] In August 2021, DeChambeau shot 27 under-par at the BMW Championship in Owings Mills, Maryland, but lost on the sixth hole of a sudden-death playoff to Patrick Cantlay.

[43] After missing the cut in the Memorial Tournament at the start of June, DeChambeau was again asked about LIV Golf, in which his answer suggested he would continue with the PGA Tour.

[48] In June 2023, DeChambeau stated in an interview with CNN that families of the victims the September 11 attacks should move forward "in forgiveness.

[51] At the 2024 PGA Championship, DeChambeau shot a final round 7-under par 64, which included a birdie on the 72nd hole, to tie leader Xander Schauffele.

Partly in response, the R&A and USGA, which jointly determine the rules of golf, to avoid troublesome issues with the effect of club length on distances, instituted a local rule from 2022 to allow competition organisers to limit the permitted length of a non-putter golf club to 46 inches.

[60] On August 6, 2023, DeChambeau won his first event on the LIV tour using a unique driver which is not usually played by professional golfers – a Krank Formula Fire LD which is designed for and primarily used by elite long-drive competitors.

[61] DeChambeau's father Jon was diagnosed with diabetes in the early 1990s, and suffered kidney failure due to the disease in 2014.

[64][65][66] In December 2017, DeChambeau played a round of golf alongside U.S. President Donald Trump, senator David Perdue, and former professional golfer Dana Quigley.
