Too nervous to look, too stunned to dance, James Hahn won the Northern Trust Open for his first PGA Tour title Sunday by holing a 25-foot birdie putt on the third extra hole at Riviera in Los Angeles.

In a wild finish off Sunset Boulevard just as the Academy Awards was getting started, Hahn wound up with the trophy against a field of far bigger names to earn his first trip to the Masters.

He got up-and-down from behind the 18th green in regulation to save par for a 2-under 69. And that turned out to be good enough for a playoff when Dustin Johnson missed a 10-foot birdie putt for the win. Johnson closed with a 69.

Paul Casey joined them in the playoff at 6-under 278 when he made bogey on the 18th hole for a 68.

Sergio Garcia finished bogey-bogey for a 71 to finish one shot out of the playoff. Jordan Spieth, thinking he needed birdie to get to 7 under for a playoff, nearly holed his aggressive chip on the 18th, and then missed the 6-foot par putt coming back. He shot 70 and missed the playoff by one, as did Keegan Bradley (68) and Hideki Matsuyama (67).

Hahn is the first player from Cal to win on the PGA Tour. He still has 72 more wins to catch up with that other Golden Bear - Jack Nicklaus - though this was a great way to start.

He gets into his first World Golf Championship in two week at Doral, and he's headed to the Masters.

Johnson, in his third tournament since returning from a six-month break to seek professional help for what he called "personal challenges," made bogey with a wedge in his hand on the par-5 17th when he hit into a bunker, costing him a clear path toward winning.
