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; he qualified his way into the U.S. Open, tied for fifteenth place for over $152,000, and improved his world ranking to 148.
Lowry made his professional debut in the 2009–10 UEFA Europa League in an away fixture at Rapid Vienna. On 17 September 2009, Lowry signed a three-month loan deal with Football League Championship side Plymouth Argyle. Lowry made his Plymouth Argyle debut on 19 September 2009, playing 90 minutes, in a 3–1 loss against Newcastle United. He played 13 league games for Plymouth during his loan spell, where he impressed many and was recalled by Villa who required Lowry's services as cover after some injuries to defenders.
After finishing fifth in the Hyundai Tournament of Champions in Hawaii, Fowler claimed his first victory of 2016 in the Abu Dhabi HSBC Golf Championship on the European Tour. He shot a final round of 69 to finish one clear of Belgium's Thomas Pieters. Two weeks later, Fowler was in contention to win again but lost out to Japan's Hideki Matsuyama in a playoff at the Waste Management Phoenix Open. On March 7, Fowler sparked fantastic scenes after sinking a hole-in-one with fellow tour pro Luke Donald's pitching wedge to win $1 million for Ernie Els' charity, Els for Autism.
What this looks like to the naked eye is a DeChambeau who is visibly larger than he was two months ago, when he first teased the idea of a bigger, stronger self. He was under 200 pounds then — now he’s 222. “I’m going to become like a gymnast. I watch online, on Instagram, these gymnast influencers, and that’s where I want to get.” It’s a step in the right direction, but 222 is not nearly big enough. DeChambeau has a Hulk-like vision for his future.
Fowler is one of four golfers in the "Golf Boys" group along with fellow PGA Tour players Ben Crane, Bubba Watson and Hunter Mahan. The Golf Boys released a YouTube video of the song "Oh Oh Oh" on the eve of the 2011 U.S. Open. Farmers Insurance is donating $1,000 for every 100,000 views of the video. The charitable proceeds will support both Farmers and Ben Crane charitable initiatives.
Some modern pros, including Woods, have caught flak for working out too hard and wearing down their bodies. For DeChambeau, the philosophy is the exact opposite: His gym inspiration is to stave off a nagging back injury. That injury — which DeChambeau says stems from a childhood trampoline accident plus the wear of hitting nearly infinite range balls — left him in major pain last season. “Sleeping hurt, everything hurt,” he said. “But it’s pretty cool what you can do to the body by working out. Most people say, ‘okay, I just have to sit down and rest, I’ve gotta take time off,’ but I’ve tried that route and I’ve realized that actually makes you worse.”
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 coming the week before, gained DeChambeau a place in the 2017 Open Championship, where he missed the cut after rounds of 76–77 (+13).
