Mickelson holds nerve to win by one shot at Riviera

PACIFIC PALISADES, California (Reuters) - American Phil Mickelson squandered a five-stroke lead before coming from two behind with three holes remaining to win the Northern Trust Open by one shot on Sunday.

Despite struggling off the tee for most of the final round, the left-hander birdied 16 and 17 before parring the last to complete a successful title defense at Riviera Country Club.

Mickelson, who had charged four ahead of the chasing pack with a blistering 62 on Saturday, clinched his 35th PGA Tour victory with a 15-under total of 269.

American Steve Stricker, who had led by two shots with two holes to play, had to settle for second place after closing with a 67.
