Web.com Tour Immediately after the Masters in mid-April 2016, DeChambeau turned professional and signed a long-term agreement with
Cobra-
Puma Golf. He made his pro debut days later at the
RBC Heritage in
South Carolina and tied for fourth, earning over
$259,000. The decision to turn professional meant the forfeiture of his exemptions to the
U.S. Open at
Oakmont and
Open Championship at
Royal Troon, but DeChambeau qualified his way into the U.S. Open and tied for 15th place to earn over $152,000, improving his
world ranking to 148. Despite the strong start, DeChambeau did not earn enough non-member
FedEx Cup points that season to qualify for a 2017 PGA Tour card but did qualify for the
Web.com Tour Finals. He was successful at earning his card through the Finals, due to a win at the
DAP Championship.
PGA Tour On July 16, 2017, DeChambeau earned his first PGA Tour victory by winning the
John Deere Classic by a single stroke over
Patrick Rodgers. He carded a round of 65 in the final round to win his maiden title in his 40th start on tour. The win gained DeChambeau a place in the
2017 Open Championship, which took place the following week. At Open, he missed the cut after rounds of 76–77 (+13). 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. After Stanley bogeyed the first hole of sudden death, DeChambeau proceeded to win with a birdie on the second hole, giving him his second victory on the tour. On August 26, 2018, he won
The Northern Trust for his first
playoff victory and, in the process, established a new record for the tournament when held at the
Ridgewood Country Club – with a score of 266 – besting the old Ridgewood record of 270, which was set in 2014 by
Hunter Mahan. 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. This put him over 2000 points ahead of second place player
Dustin Johnson in the
FedEx Cup rankings. This margin secured him top seeding at The Tour Championship, regardless of his finish at the BMW Championship. This also marked his fourth win on the tour, third for the year, and second in a FedEx Cup playoff event. At the
Tour Championship, DeChambeau finished 19th out of 30 participants. As a result, he fell to 3rd in the
FedEx Cup, winning $2,000,000. 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. Europe defeated the U.S. team, 17½ points to 10½ points. DeChambeau went 0–3–0. He lost his singles match against
Alex Norén. On November 4, 2018, DeChambeau won the
Shriners Hospitals for Children Open in Las Vegas, Nevada. The win was worth $1,260,000 in prize money. The win brought him to number five in the Official World Golf Ranking. On January 27, 2019, DeChambeau won the
Omega Dubai Desert Classic in Dubai, UAE. DeChambeau claimed his maiden European Tour title by producing a closing 64 to win the tournament by seven shots. In December 2019, DeChambeau played on the U.S. team at the
2019 Presidents Cup at
Royal Melbourne Golf Club in Australia. The U.S. team won 16–14. DeChambeau went 0–1–1 and halved his Sunday singles match against
Adam Hadwin. in 2020 Beginning in late 2019, DeChambeau set out to add muscle mass in order to increase his swing speed and hit the ball farther. He added 20 pounds before the tour's break due to the
COVID-19 pandemic and another 20 during the break. When the tour resumed, he quickly moved to the lead in driving distance. On July 5, 2020, DeChambeau won the
Rocket Mortgage Classic in
Detroit, Michigan, by three strokes over
Matthew Wolff. In the final round, DeChambeau shot a 7-under 65 at
Detroit Golf Club, birdieing four of the first seven holes and closing with three consecutive birdies. He finished at a career-best 23-under 265. DeChambeau came into the week with six straight top-eight finishes and was the only player with top-10s in the first three events after the restart from the coronavirus. In the second round of the 2020
Memorial Tournament in July, DeChambeau's second shot at the 15th went
out of bounds under a fence. He argued that only part of the ball was out of bounds, and he should be allowed to play it, but PGA Tour rules official Ken Tackett ruled against him. DeChambeau asked for a ruling from a second official, who confirmed the initial ruling. He went on to shoot a quintuple-bogey 10 on the hole and miss the
cut. 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. He argued that there were "red ants" in the area of the ball, and asked for a free drop regarding cases "when a dangerous animal near a ball could cause serious physical injury to the player". Ultimately Tackett, also the rules official in this incident, stated the ball had to be played as it lay. DeChambeau finished the hole with a double-bogey 6. In August 2020, DeChambeau briefly held a share of the lead during the final round of the
PGA Championship; he went on to finish in a tie for fourth place, his first top-10 finish in a major championship. Six weeks later, at the
120th U.S. Open at
Winged Foot, he came from two strokes behind at the start of the final round to win his first major championship. His six-under par total gave him a six stroke victory over
Matthew Wolff. He was the only player under par in the final round, with a three-under par 67 and the only player to finish under
par for the tournament. With the win, he became the third player in history, after Jack Nicklaus and Tiger Woods, to win the NCAA Individual Championship, the U.S. Amateur and the U.S. Open during a career. 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. In March 2021, DeChambeau won the
Arnold Palmer Invitational at Bay Hill Club & Lodge in Orlando, Florida. He shot a final round one-under 71 to defeat
Lee Westwood by one shot. After shooting an opening round 1-over 71 at the 2021 Open Championship, DeChambeau placed blame on his driver, saying after the round, "That's what I said a couple of days ago; if I can hit it down the middle of the fairway, that's great, but with the driver right now, the driver sucks". 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. Schomin told
Golfweek, "It's just really, really painful when he says something that stupid. He has never really been happy, ever. Like, it's very rare when he's happy". DeChambeau would later issue an apology on Instagram. in 2021 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. In September 2021, DeChambeau played on the U.S. team in the
2021 Ryder Cup at
Whistling Straits in
Kohler, Wisconsin. The U.S. team won 19–9 and Dechambeau went 2–0–1 and won his Sunday singles match against
Sergio García.
LIV Golf 2022–2023 In February 2022, amid speculation that he was joining the
Saudi-backed
LIV Golf tour, DeChambeau released a statement committing to the PGA Tour. In April 2022, DeChambeau announced that he had surgery on his left wrist and would be taking the appropriate time to rest and recover. 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. However, a few days later on June 8,
The Daily Telegraph reported that DeChambeau would be joining LIV Golf. On June 10, LIV Golf confirmed that DeChambeau had joined the tour. As a result of joining LIV Golf,
Rocket Mortgage ended its sponsorship deal with DeChambeau. 911familiesunited.org, a coalition of families and survivors of the
September 11 attacks, sent a scathing letter to representatives of DeChambeau as well as other LIV Golf members, expressing their outrage toward the golfers for participating in LIV Golf and accusing them of
sportswashing and betraying the United States. In June 2023, DeChambeau stated in an interview with
CNN that families of the victims of the September 11 attacks should move forward "in forgiveness". He continued, stating "We'll never be able to repay the families back for what exactly happened just over 20 years ago, and what happened is definitely horrible... We're in a place now where it's time to start trying to work together to make things better together as a whole." In August 2023 at
The Greenbrier, DeChambeau won his first tournament on LIV Golf. He followed up a 61 in the second round, with a new tour record of 58 in the third and final round, which also tied the record for
lowest round in an elite-level men's professional golf tournament. In September, he won his second tournament on the LIV tour, at
LIV Golf Chicago. He shot a final-round 63, including a 28 on the back nine, to win by one stroke.
2024–present 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. Schauffele then went on to birdie the 72nd hole himself to win by one stroke. At the
2024 U.S. Open, DeChambeau got up and down from 55 yards away in the bunker on the 72nd hole to win his second major title, shooting 6-under for the tournament, one stroke ahead of
Rory McIlroy. The broadcast of the tournament featuring DeChambeau's battle against McIlroy drew a peak viewership of 11.4 million, the highest since the
2015 U.S. Open. Three weeks later, DeChambeau shot 19-under 197 to win the LIV Golf Korea event, his first LIV Golf victory since September 2023. At the
2025 PGA Championship in May, DeChambeau finished runner-up alongside
Harris English and
Davis Riley, five strokes behind
Scottie Scheffler. As defending champion at the
2025 U.S. Open in June, DeChambeau shot rounds of 73-77 at
Oakmont Country Club to total 10-over and missed the cut. He was the first defending U.S. Open champion to miss the cut since
Gary Woodland in 2020. DeChambeau opened with a 7-over 78 at the
2025 Open Championship in July, but rallied with a 65 to make the cut on the number. He shot 68-64 on the weekend to finish inside the top 10. DeChambeau was an automatic qualifier for the United States team in the
2025 Ryder Cup. He had a record, including a tie in his singles match against
Matt Fitzpatrick, as the United States lost by a score of 15–13. In March 2026, DeChambeau won the LIV Golf Singapore event in a playoff over
Richard T. Lee. The following week, DeChambeau shot 26-under 258 to tie for first alongside
Jon Rahm at LIV Golf South Africa. He made birdie on the first playoff hole to defeat Rahm and claim the victory. This made him the third man to have won five or more LIV Golf titles, joining
Brooks Koepka and
Joaquín Niemann. ==Unique clubs==
