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).
Kolon Korea Open: Won his first tournament as a professional, the Kolon Korea Open on the OneAsia Tour, when he rolled to a six-stroke win over Rory McIlroy at Woo Jeong Hills CC in early October. He took control of the tournament in the third round when he shot an 8-under 63. He followed that with a 3-under 68 Sunday. The victory was worth a little under $250,000.
Shell Houston Open: After opening with an 8-under 64 for a one-stroke lead on day one, added rounds of 71-67-70 to finish T3 at the Shell Houston Open. Erased a seven-shot deficit in the third round and started the final round three shots behind 54-hole leader Sung Kang, but a final-round 70 saw him finish four strokes behind winner Russell Henley. With 27 birdies on the week (tied for most with Henley), marked his most birdies in a single event.
Lowry elected to turn professional the week after his Irish Open triumph, meaning that he would miss out on the opportunity to play in the Walker Cup in September 2009. He made his professional début on 28 May at the European Open, where he shot 78 in the first round to end the opening day almost at the back of the field, and went on to miss the cut following a second round 73.
