Lin won the first playoff in the 11-year-history of the Asia-Pacific Amateur and joined Hideki Matsuyama as the only two-time winners. The victory gets Lin into the Masters and the British Open next year.
He thought he had thrown away his chance when he laid up into the water on the par-5 18th hole at Sheshan International, making bogey for a 68. Kanaya had a chance to win in regulation, but missed a 7-foot birdie putt.
Both made birdie on the 18th on the first extra hole. Lin blasted out to 3 feet and made the winning putt.
