Bill Haas made the biggest putt of them all Sunday at Riviera -- the putt that won the Northern Trust Open.
Haas closed with a 2-under 69 and wound up in a three-way playoff when Phil Mickelson made a birdie putt from just outside 25 feet on the 18th hole, and PGA champion Keegan Bradley joined him with a 12-foot birdie putt.
The tournament was decided on the second extra hole, the par-4 10th, perhaps the most interesting par 4 in golf. Haas had to play safe from behind the green, then rolled in a 45-foot birdie putt.
Mickelson was short and hit a flop shot over the green into a bunker. Bradley missed a 15-foot putt to extend the playoff.
Haas won for the fourth time in his career.
