Gonzalo Fernandez-Castano's chip in for birdie on the tough 17th hole turned out to be the winning shot for him Sunday in the BMW Masters.

The 33-year-old Spaniard was flawless at Lake Malaren until it no longer mattered. The birdie gave him a three-shot lead playing the final hole, and Fernandez-Castano played it so poorly that he had to make a 2-foot putt for double bogey to win by a shot.

Fernandez-Castano closed with a 4-under 68 for a one-shot win over Francesco Molinari (64) and Thongchai Jaidee (66).

Luke Guthrie, the 23-year-old American making his first trip to Asia, lost the lead for the first time with a bogey on the opening hole and never got it back. He closed with a 71 to finish alone in fourth.
