John Cook caught David Frost on the final hole of regulation, then beat him with birdie on the second playoff hole to win the Mitsubishi Electric Championship on Sunday.
Cook closed with a 5-under-67 at Hualalai Golf Club to catch Frost at 17-under 199. Cook drained a 25-foot birdie putt on the 18th green.
Frost shot 69, not able to match Cook's birdie on the 54th hole of the Champions Tour season-opener.
Frost had held the lead alone since the 12th hole Saturday.
Both birdied the first playoff hole (No. 18) from inside 10 feet and went to the 17th tee. Cook hit his tee shot about 15 feet left of the hole and drained it after Frost had come up short with his birdie try.
Cook did not have bogey all week while Frost went bogey-free over his last 48 holes.
Bernhard Langer chipped in on the last hole to finish third alone at 200. He started six back and bogeyed two of the first three before getting birdies on nine of the next 11 holes and finishing with a 64.
