Frys.com Open: At the Frys.com Open in Scottsdale, Ariz., reached a three-way playoff with Jamie Lovemark and eventual-winner Troy Matteson. Began the final round four strokes behind Matteson, but played his first five holes in 5-under, punctuated by a hole-in-one from 211 yards at the par-3 fifth hole. After finishing T2 in the playoff, he had recorded all eight of his professional rounds in the 60s. Thanks to the T7 in Las Vegas at the Justin Timberlake Shriners Hospitals for Children Open and T2 finish at Grayhawk GC, he surpassed No. 150 from the 2008 money list, earning special temporary membership on TOUR for the remainder of the season.
Wells Fargo Championship: Made birdie-3 on the first extra hole (No. 18) to defeat Rory McIlroy and D.A. Points at the Wells Fargo Championship for his first TOUR win. Improved to 1-1 in playoffs (lost to Troy Matteson, 2009 Frys.com Open). The playoff was the fifth at the Wells Fargo Championship. At the age of 23 years, 4 months, 23 days, became the third player to make the Wells Fargo Championship his first PGA TOUR win (Anthony Kim in 2008 and McIlroy in 2010). Became the third-youngest winner of the event, behind McIlroy (20 years, 11 months, 28 days) and Kim (22, 10, 15). His win came in his 72nd start on TOUR and was his 16th top-10 finish. Opening-round 66 is the lowest start by a winner of the Wells Fargo Championship. Won in his third start at the Wells Fargo Championship (T6 in 2010 and T16 in 2011).
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.
Waste Management Phoenix Open: Claimed his second runner-up finish at the Waste Management Phoenix Open, one shot behind Hunter Mahan. Had birdie opportunities on the last three holes but unable to catch Mahan. Previously lost in a playoff to Troy Matteson just down the road at Grayhawk GC in the 2009 Frys.com Open. Had he won at TPC Scottsdale, would have become the first Sponsor Exemption to do so since Jason Gore (2005 84 Lumber Classic). Lee Westwood later won in June as a Sponsor Exemption at the St. Jude Classic presented by Smith & Nephew.
