He shot a closing 70 to finish regulation locked with Marino
(70) at 12-under-par 276, one stroke ahead of Mexican Rodolfo
Cazaubon (68) and third-round leader Ian Poulter, of England,
who carded 72.
Finau played his final eight holes in two-over in windy
conditions at Coco Bach to allow Marino to extra holes.
They played the par-five 18th three times in the playoff. Both
players birdied the first two times, but Marino could not match
Finau's birdie on the third try, when the latter got up-and-down
from a greenside bunker, while Marino’s putt from just outside
four feet missed to the right.
"I learned a lot being in contention (at several tournaments)
last year," Finau told PGATour.com. "I learned you have to take
the good with the bad.
"I'm proud of the way I stuck in there and happy I made that
last putt when I needed to."
Runner-up Marino remained winless in 182 starts on the PGA Tour.
Poulter, winless in four years, closed with 13 consecutive pars
and missed an 18-foot birdie putt at the last to narrowly miss
out on the playoff.
