At the PGA Championship, Fowler carded 74-69-75-68 to finish with a six-over par total of 286, in a tie for 51st place. Early on the third day Fowler rocketed up the leaderboard with three birdies in the first five holes only to falter later in the round with two triple bogeys, effectively ending his hopes of a first major championship and PGA Tour win.
At the 2016 U.S. Open at Oakmont Country Club near Pittsburgh, Lowry shot 65 (−5) in the third round for 203 (−7) and a four-stroke advantage over Dustin Johnson and Andrew Landry at the 54-hole stage. The 65 was Lowry's joint career best round at a major championship. Due to weather delays on Thursday, the third round was not completed until early on Sunday, and Lowry birdied two of his remaining four holes to extend his two stroke overnight lead to four. In the final round he was in contention for the title, within one shot of Dustin Johnson after 12 holes, before three consecutive bogeys on holes 14, 15 and 16 ended his chances. He finished the tournament tied for second place, with a final round score of 76.
On June 16, Fowler carded a round of 65 at Erin Hills to take the first round lead at the 2017 U.S. Open. Fowler equaled the lowest first round score at the U.S. Open and led by one stroke from Paul Casey and Xander Schauffele. He followed this up with a one over par 73 in the second round to fall out of the lead by one stroke, held by four other players. He shot 68-72 over the weekend to finish in a tie for fifth place. This gave Fowler his sixth top-5 finish in a major, but he is still yet to win. Fowler started the PGA Championship with a 2-under 69 which was two strokes behind the leaders. After rounds of 70-73, he closed out the year's last major with a 4-under 67, including a run of four consecutive birdies on holes 12 through 15. Despite his solid finish, Fowler ended up tied for fifth and was 3 strokes behind the winner, and friend, Justin Thomas. It was his seventh top-5 major finish, meaning he's had multiple top-5 finishes at every major.
Abu Dhabi HSBC Golf Championship: Held off final-round charges from Thomas Pieters, Rory McIlroy and Henrik Stenson to win the Abu Dhabi HSBC Golf Championship, marking his second European Tour title. The victory was the first at the event by an American since Chris DiMarco won the inaugural event in 2006. Final-round highlights included a holed bunker shot on the eighth hole (which helped propel him to a three-stroke cushion at the turn), a chip-in for birdie on the 17th hole and then a par on the last to hold off Pieters by one stroke.
Nationwide Tour Players Cup: Playoff runner-up to Derek Lamely at the Nationwide Children's Hospital Invitational. Started the final round five shots behind 54-hole leader Dave Schultz. Held the lead during much of the final round but suffered a bogey at the 72nd hole of regulation to drop into a tie with Lamely and force a playoff. Lost to Lamely when he failed to get up and down from a greenside bunker on the second extra hole, missing his par putt of 12 feet. Lamely rolled in a three-foot par putt to win.
All of DeChambeau's irons and wedges are cut to exactly the same length: 37.5 inches (95.3 cm). Their lie and bounce angle are also the same; only the lofts are different. In addition to the single-length concept, his clubs are unusual for their extremely upright lie angle.  DeChambeau keeps the club on the same plane throughout his swing and does not turn his wrists during his swing. In 2011, at the suggestion of his instructor Mike Schy, DeChambeau switched to JumboMax Grips, the largest grips commercially available. The larger grips allow DeChambeau to hold the grips in his palms and not his fingers.
The Open Championship: Playing in the final group Sunday for the second straight time in a major championship, made a solid bid for the title, at The Open Championship, with a final-round, 5-under 67. Along with Garcia, finished second to Rory McIlroy by two strokes. With his finish at Royal Liverpool GC, became the only player of the season to claim top-five finishes in the year's first three major championships. He also became the first player to claim top-10 finishes in a season's first three majors since Woods achieved the feat in 2005. His T2 at Royal Liverpool supplanted his previous-best Open Championship finish (in four starts) of T5 in 2011. Rounds of 69-69-68-67 made him the only player in the field to post all four rounds in the 60s.
While serving a suspension, Lowry signed a two-and-a-half-year permanent deal to Millwall for an undisclosed fee on 27 January 2012. Lowry then made his first appearance for the club since joining Millwall permanently, playing 90 minutes, in a 2–1 loss against rivals' West Ham United on 4 February 2012. Right way through March, Lowry was sidelined with ankle injury that kept him out for weeks. After making his first team return against Cardiff City, in a 0–0 draw on 31 March 2012, Lowry scored his first Millwall goal, which he scored the only goal in the game, in a 1–0 win over Coventry City on 17 March 2012. Lowry finished his 2011–12 season, making twenty-two appearance and scoring once.
