Tony Finau won the Puerto Rico Open on Sunday at windy Coco Beach for his first PGA Tour title, beating Steve Marino with a birdie on the third hole of a playoff.

The 23-year-old Finau won with his third straight birdie on the par-5 18th, blasting out of the back bunker to 3 feet. Marino was just off the back edge of the green in two, but left his putt from the fringe 4 1/2 short and missed his birdie try to the right.

Finau and Marino each shot 2-under 70 to finish at 12-under 276. Marino birdied the 18th to tie Finau, and got into the playoff when Finau missed a 6-foot birdie putt.

Finau and Marino each birdied the 18th on the first two playoff holes.

Ian Poulter and Mexico's Rodolfo Cazaubon finished a stroke out of the playoff.
