Mickelson completes West Coast trophy collection at Riviera C.C.

Phil Mickelson held on long enough for Jeff Quinney to self-destruct on the back nine Sunday at Riviera Country Club, closing with a 1-under 70 to win the Northern Trust Open and complete an impressive collection of trophies in California and Arizona.

A year ago, Lefty was poised to win in Los Angeles until he bogeyed the 18th hole and lost in a playoff against Charles Howell III. This time, he was steady down the stretch as Quinney faltered, and won by two shots for his 33rd career victory, 16 of those on the West Coast.

"It's pretty cool," Mickelson said. "I've wanted to win this tournament for a long time."

Quinney's time will have to wait.

He holed four straight putts outside 10 feet around the turn and briefly held the lead. But his streak of 214 holes without a three-putt ended on the 13th to fall out of the lead, and Quinney soon fell apart.

"I just put a little too much pressure on the putter on the back nine," said Quinney, who made a 25-foot birdie putt on the 18th hole that only changed the final score. He closed with a 71.

British Open champion Padraig Harrington and Luke Donald each shot 68 and tied for third.

Mickelson finished at 12-under 272 and earned $1,116,000.

He might never catch Tiger Woods in the world ranking, PGA Tour victories or in the majors, but for now he has done something the world's No. 1 player hasn't -- win at Riviera.

The victory came one week after taking an 11 on the 14th hole at Pebble Beach to miss the cut, and two weeks after he lost a playoff to J.B. Holmes in the FBR Open.

Champions Tour

Scott Hoch made it back-to-back wins on the Champions Tour.

Hoch made an 8-foot birdie putt on the last hole of regulation to get in a four-way playoff, then made another 8-footer on the first playoff hole to win The ACE Group Classic in Naples, Fla.

Tom Jenkins, Tom Kite and Brad Bryant had already made their pars before Hoch.

Hoch won the Allianz Championship in his previous tournament.
