KAUPULEHU-KONA, Hawaii — 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 made a 16-foot birdie putt on the 18th green.
Frost shot a 69, missing a 15-foot birdie putt at the 18th that would have given him a win in the Champions Tour season-opener. He had held the lead alone since the 12th hole of the second round.
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 20-foot birdie try.
Cook won $309,000 for his ninth victory on the senior tour, to go along with 11 on the regular PGA Tour.
He birdied all four par-5 holes on Sunday, while Frost birdied just one.
