PGA Tour
Gainey played on the PGA Tour for the first time in 2008, but struggled for most of the season. He made only five cuts in 23 events and was 228th on the money list, before entering the last event of the season, the Children's Miracle Network Classic at the Walt Disney World Resort. In the last round, playing the Magnolia Course, he shot a 64 and finished second to Davis Love III by one stroke. That finish moved Gainey inside the top 150 on the money list (to 148th, an 80-spot leap), which gave him conditional status for the 2009 season. Gainey re-entered the Q-School to try and gain back full playing privileges, but finished well down the leaderboard in T80th. He then split his time between both the PGA Tour and Nationwide Tour in 2009, struggling again on the PGA Tour, making just 8 out of 15 cuts, with one top-25 finish. He ended the year 202nd on the money list, not even earning conditional status for 2010. [4]
Gainey returned to the Nationwide Tour in 2010, where he played the full season. He recorded some impressive results, claiming his first Nationwide Tour title at the Melwood Prince George's County Open in June. Gainey won the event by one stroke over Frank Lickliter and Jin Park, with weekend rounds of 64 and 65 securing victory. The following month, Gainey won his second Nationwide Tour title at the Chiquita Classic, winning by three strokes over Joe Affrunti. He shot a 10 under round of 62 in round three on the way to the win. He finished the season fourth on the Nationwide Tour money list and secured a return to the PGA Tour in 2011.
In 2011, Gainey missed the cut in his first three events, then made six consecutive cuts through to the end of March. At the 2011 Waste Management Phoenix Open in Scottsdale, Arizona, he was in contention late in the final round, but made a quadruple-bogey 8 on the par-4 17th hole to finish tied for 8th. [5] He posted a fifth-place finish at the Honda Classic in Florida a month later. [5] Gainey's best 2011 Tour finish came at The Heritage in Hilton Head, South Carolina, when he needed a 15-foot putt on the 72nd green to tie clubhouse leader Brandt Snedeker, but missed it, finishing the event in third place. [5] The next week on tour, Gainey finished in a tie for third again at the Zurich Classic of New Orleans, where he finished two strokes outside of a playoff. In August, due to his good play for the year, Gainey qualified to play in his first major championship at the PGA Championship at the Atlanta Athletic Club. He shot rounds of 81 and 74 to miss the cut, but bounced back with a third-place finish the next week at the Wyndham Championship. The third occasion in 2011 that Gainey had finished in the top three in an event. The result moved him to a career high of 84th in the world rankings. [6] [7] Gainey ended his breakthrough year with another T3rd finish at the Justin Timberlake Shriners Hospitals for Children Open in the Fall Series. Gainey ended the year 35th on the money list. with 17 cuts and 7 top-10s in 34 events.
Gainey started the 2012 season slowly, making only three of his first ten cuts, having to withdraw twice due to injury. He did not record a top 10 finish until the end of May at the Crowne Plaza Invitational at Colonial where he finished third for the fifth time in his career on the PGA Tour. For the rest of the season, Gainey played more consistently, making nine of the next thirteen cuts, but without any significant results. Then on October 21, 2012, during the Fall Series, after 105 starts and 48 cuts made, Gainey won his first PGA Tour event at the McGladrey Classic. He came from seven strokes back of final round leaders Jim Furyk and Davis Love III to win by one from David Toms, after shooting a final round of 60. Gainey had a putt from about 20 feet on the 18th green for a 59 but it missed on the right hand side. [8]
In January 2020, Gainey won The Bahamas Great Exuma Classic on the Korn Ferry Tour, his first professional win since 2012. His winning score was 277 (11-under-par). He started the season with limited status on the PGA Tour as a past champion and on the Korn Ferry Tour after a T76 finish at Q School.
