All of DeChambeau's irons and wedges[24] 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. [25] DeChambeau keeps the club on the same plane throughout his swing and does not turn his wrists during his swing.[26] 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.
Lowry was the 2007 Irish Amateur Close Champion, defeating Niall Turner 4 & 3 in the final.[5] While still an amateur in May 2009, he won The Irish Open on the European Tour, defeating Robert Rock on the third hole of a sudden death playoff. The win, on his tour début, made him just the third amateur to win on the European Tour,[6] following Danny Lee earlier in the 2009 season, and Pablo Martín in 2007. Lowry shot a 62 to equal the lowest ever by an amateur on the circuit and led from the second round onwards.[7]
Lowry missed the first three cuts of his professional career, but had his first payday on 5 July, when he finished 50th at the Open de France ALSTOM.[13] He had his best professional result in November 2009, when he finished 3rd in the Dunlop Phoenix Tournament in Japan.[14] In January 2010, Lowry finished in fourth place in the Abu Dhabi Golf Championship,[15] moving him into the top-100 of the Official World Golf Ranking.[16]
Lowry started for Leeds in the Football League Trophy Northern Area Final, second leg game against Carlisle United, in which the game was lost with Lowry missing the decisive penalty in sudden death in the penalty shootout. After the game it appeared as though Lowry was attacked by a set of Carlisle supporters who had invaded the pitch.[11] After starting every game for Leeds Lowry was dropped from the Leeds squad for the match against Brentford after suffering an injury, before returning to Villa when his loan spell ended. On 25 March 2010 Lowry re-signed for Leeds for a second loan spell, with his loan lasting until the end of the season.[12] Lowry started at left back for Leeds against Norwich City on his return to the club, a match Leeds went on to lose 1–0 in injury time.[13] Lowry didn't overley impress the Leeds fans in his loan spell at Leeds, with him being mostly played out of position at Left back for the entire spell, he was substituted for Jonathan Howson in the final game of the season against Bristol Rovers with 1–0 down at the time, but his loan spell ended on a high as Leeds were promoted in 2nd place after scoring two goals to go on and beat Bristol Rovers and secure promotion to The Championship.[14]

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.

Rounds of 69-69-68-67 made him the only player in the field to post all four rounds in the 60s.

Though he appeared in two matches as an un-used substitute for Aston Villa in the 2010–11 season, Lowry continued to be remain out of the first team and in January 2011, Lowry signed for Championship side Sheffield United until the end of the season[17] making his first start for the Blades away at Coventry City a day later.[18] Lowry made eighteen appearances for the Blades but with the club in decline he was unable to prevent them from being relegated at the end of the season.[14]

Recorded his fifth career runner-up finish on TOUR in his 73rd start. His T2 performance came in his third start at THE PLAYERS and first in which he made the 36-hole cut.
