Amazing 64 sees Goosen storm into lead

Retief Goosen shot a sizzling eight-under-par 64 today to surge to the top of the leaderboard after two rounds of the Pebble Beach National Pro-Am, seizing a two-shot advantage over Dustin Johnson.

An eagle on the first hole provided the springboard to the magnificent round by Goosen, who moved to 12-under 132 for the tournament.

Three-time Major champion and reigning PGA Player of the Year Padraig Harrington sits at three-over after the second round.

First-round co-leader Johnson is alone in second place following a three-under 69. Starting on the back nine, Johnson also got out of the gate quickly with four birdies in his first six holes before a double-bogey at 17 slowed him down.

Robert Garrigus, who shared the first-round lead with Johnson after an opening 66, carded a 71 and is tied with Charley Hoffman, Mike Weir and Mark Calcavecchia for third place at eight-under 136.

Seeking his first career win, Garrigus got off to a bumpy start with back-to-back bogeys on holes five and six but managed to battle back and get under par for his round.

Hoffman had a roller-coaster round that featured an eagle, a double-bogey, two bogeys and four birdies en route to a two-under 70.

A lefthander from Canada and the 2003 Masters champion, Weir shot an even-par 36 on the front-nine before carding three birdies after the turn to shoot a round of 69.

Defending champion Steve Lowery started his round on the back nine and birdied four of his first five holes to climb to five-under for the tournament.

Last year, Lowery broke an eight-year victory drought and picked up his third PGA Tour title with a birdie on the first play-off hole to outlast Vijay Singh. Lowery entered the final round three strokes off the lead.

The 2002 PGA champion, Rich Beem birdied the first two holes to climb to 8-under before bogeying five of his final 12 holes to finish at three-under through two rounds.

Singh is also in the field this week, making his second start of the season. He struggled Friday with four bogeys and a birdie to fall to three-over.

The winner of this event in 2004, Singh is making his return to the Tour after undergoing arthroscopic surgery on his right knee in mid-January to repair a torn meniscus.

Also in the field are Jim Furyk and Phil Mickelson at three-under at one-under respectively.

Furyk is coming off a 2008 season in which he led the tour in top-10 finishes with nine. However, he failed to record a victory for the first time since the 2004 season.

Mickelson has had success here, as the Pebble Beach Pro-Am is one of four events he has won three or more times. Mickelson, who won here by five strokes in 2007, has five top-three finishes in 13 appearances.
