Fabian Gomez held a 1-stroke advantage entering the final hole of the Puerto Rico Open on Sunday, but he bogeyed the par-5 18th, while playing partner Scott Brown birdied for his first PGA Tour win.
Brown, playing on conditional status after finishing 148th on the PGA Tour money list last year, carded a final-round 2-under 70 and finished 72 holes at a tournament-record 20-under 268. Now, with his first career win on the tour, the 29-year-old has his card back and a spot in the PGA Championship later this summer.
Gomez, who was also seeking his first PGA Tour title, ended with a final-round 71 on the Composite Course at Trump International Golf Club and tied for second place with 19-year-old Jordan Spieth (67) at 19-under.
Justin Bolli (66) and Brian Stuard (68) shared fourth at 18-under, while former U.S. Amateur champion Peter Uihlein (67) and second-round leader Andres Romero (66) tied for sixth at 17-under.
Boo Weekley (68), David Hearn (66) and D.J. Trahan (66) placed eighth at 16- under and Dicky Pride (66), Robert Streb (67) and Brendon de Jonge (69) ended in 11th at minus-15
Brown and Gomez shared the overnight lead after setting a new 54-hole tournament record, but the former quickly grabbed a 2-stroke lead on Sunday courtesy of an eagle on the par-5 second.
Brown padded his advantage with a birdie at the fifth, but he failed to stay on top, due largely to a run of three straight bogeys starting at the eighth.
Both Gomez and Spieth took advantage of Brown's misstep, with the Argentine picking up a birdie at the sixth to pull even at the turn.
Spieth, meanwhile, carded four birdies during his sparkling outward nine -- including a run of three straight beginning at the fifth. The teenager picked up another shot at the 10th to pull even with the overnight leaders at 19- under.
Brown briefly lost grip of the lead with his birdie on the 11th, but he bounced back with a birdie on the next hole.
The trio were all square through 12, before Gomez went on a birdie-bogey- birdie run over his next three holes to go ahead by a shot.
Spieth fell two strokes off the pace with a bogey on the 16th, eventually ending in second place after a birdie on the last.
Brown, meanwhile, recorded five straight pars after his birdie on the 12th, setting up the dramatic conclusion.
Gomez's initial gaffe on the 18th came when he sailed his third shot over the green and into a bunker. He escaped to 15 feet, but he missed the par putt and settled for bogey, allowing Brown to seal it with a birdie roll.
