In December 2009, Fowler successfully gained his PGA Tour card for 2010 through qualifying school, finishing T15.
In February 2010, Fowler finished second at the Waste Management Phoenix Open with a score of 15 under par at the TPC of Scottsdale course. In June, Fowler notched his third PGA Tour runner-up finish at the Memorial Tournament in Dublin, Ohio. Fowler entered the final round in the lead, but shot a 73 to finish behind Justin Rose, who recorded his first PGA Tour victory. This performance took Fowler into the top 50 of the Official World Golf Ranking.
In September, he signed a clothing deal with Puma. In the same month, he was also chosen as a captain's pick for the U.S. Ryder Cup team. At age 21 years and 9 months when the matches began, Fowler became the youngest U.S. Ryder Cup player of all time, and only European Sergio Garcia was younger when he made his Ryder Cup debut in 1999. Fowler forfeited a hole during foursomes competition on the first match day because of a rules violation, by taking a permissible free drop from muddy conditions in an improper location, a mistake U.S. captain Corey Pavin attributed to Fowler's inexperience. On the final day of the competition in his singles match against Edoardo Molinari, Fowler birdied the last 4 holes to halve the match after having been 4 down after 12 holes.
Fowler won the Rookie of the Year award, controversially claiming the award over Northern Ireland's Rory McIlroy.
In July 2011, Fowler tied the 54-hole lead at the AT&T National, but an early double bogey on Sunday derailed his opportunity for his first PGA Tour win. Two weeks later Fowler recorded his most successful result to date in a major tournament by finishing tied for 5th in The Open Championship at Royal St George's. In August, Fowler finished in a tie for second at the WGC-Bridgestone Invitational behind winner Adam Scott, lifting him to 28 in the world rankings.
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 first FedEx Cup playoff event, Fowler finished T52 at The Barclays in the last week in August. The following week he again finished T52 at the Deutsche Bank Championship, the second FedEx Cup playoff event, after carding a disappointing six over par final round 77. At that point Fowler was positioned 37 in the FedEx Cup points standings and required a strong performance at the BMW Championship to qualify in the top thirty for the The Tour Championship; a performance which eluded him, finishing in 48th place. In finishing 43rd in the FedEx Cup, Fowler earned a $132,000 bonus.
In October, Fowler enjoyed his first professional win with victory in the OneAsia Tour's Kolon Korea Open, securing a six shot victory over Rory McIlroy.
Fowler ended 2011 ranked 32nd in the world.
In September, Fowler, along with Graeme McDowell, was part of the PGA Tour's These Guys are Good campaign.
In May 2012, Fowler won the Wells Fargo Championship in Charlotte on the first extra hole of a sudden-death playoff. Replaying the 18th hole, he defeated Rory McIlroy and D. A. Points with a birdie to gain his first PGA Tour win. Fowler shot a 69 (-3) in the final round to finish in a three-way tie after 72 holes at Quail Hollow Club. This win enabled Fowler to break the top-25 in the world, placing him at number 24. The following week at The Players Championship in Ponte Vedra Beach, Florida, Fowler played the final hole at -11 under par and had a birdie opportunity to bring him within one of leader and eventual winner Matt Kuchar. Fowler, however, pushed his putt to the right and finished in a tie for second, his fifth second-place finish of his career.
After a tie for fifth at the Masters in April, Fowler had his best finish of 2014 at the U.S. Open at Pinehurst No. 2 in North Carolina. Fowler was runner-up with Erik Compton at -1, best finishes for both at a major, but they were eight stroke behind champion Martin Kaymer. Fowler had another second-place finish at the Open Championship at Royal Liverpool Golf Club in Hoylake, England. He began the final round six strokes behind Rory McIlroy and finished the day tied for second with Sergio Garcia at -15, two strokes behind McIlroy. At the next major in August, the PGA Championship, Fowler, Phil Mickelson, Henrik Stenson, and Rory McIlroy battled for the title on a rain-soaked Valhalla Golf Club, near Louisville. Despite holding the lead for a good portion of the day, Fowler tied for third. He is only the third player, along with Jack Nicklaus and Tiger Woods, to have finished in the top 5 in all four majors in one calendar year, but the first not to win. Fowler had ten top-10 finishes during the 2013-14 season. His 8th-place finish at The Tour Championship moved him to 10th in the world golf rankings.
After a T-12 finish at the Masters, Fowler earned his first win in over three years with a playoff victory at The Players Championship in May. Trailing Sergio Garcia midway through the final round by five shots, Fowler played the final six holes in 6-under par, including an eagle at the par-5 16th. After a birdie at the famous 17th hole, Fowler's final birdie of the round on 18 left him at 12-under par. Both Garcia and Kevin Kisner had birdie attempts to win at the 18th in regulation, but both missed and the three men went to a three-hole aggregate playoff to decide a winner on holes 16-18. Fowler and Kisner went par-birdie-par to tie at -1 while Garcia's three pars left him at even and he was eliminated. Thus Fowler and Kisner went to sudden death starting at the 17th, where Kisner's tee shot landed within about 12 feet (3.7 m) of the cup. Fowler answered with a shot inside of five feet, and when Kisner's birdie attempt slid by, Fowler responded by making his short birdie to claim the championship. Fowler played his final 10 holes in 8-under par.  On July 12, he won the Aberdeen Asset Management Scottish Open on the European Tour, shooting a 12-under-par 268.
