South Korea's Charlie Wi holds a three-shot lead in the Pebble Beach National Pro-Am after shooting a three-under round of 69 on a second day which saw Tiger Woods fall six shots off the pace.
With the weather changing from sunny to drizzle through the day Woods shot a two-under 68 on the easiest of the three courses, the Monterey Peninsula Country Club, to lie at six-under at the halfway stage.
Wi made just 29 putts but his up and down round included five birdies, an eagle and four bogeys.
Dustin Johnson, a winner of the tournament in 2009 and 2010, shot an even-par 72 on Spyglass Hill to sit three shots behind Wi.
Bumpy
Woods told the PGA Tour website: "Drove it good again today, unfortunately just didn't make enough birdies."
Lying in a tie for 16th, Woods added about the deteriorating weather: "The golf course got a little interesting coming in.
"I was hitting the ball in the wrong spots. And the greens started to get a little bumpy with the softer conditions."
Ireland's Padraig Harrington ended the day in a tie for third at eight-under.
Harrington added a 66 to his first round 68 to join Americans Brian Gay and Brendon Todd, Fiji's Vijay Singh and New Zealand's Danny Lee.
England's Greg Owen added a 67 to his opening 68 to sit on seven-under in a nine-way tie for eighth.
Russell Knox finished the day on three-under, two shots ahead of fellow Scottish golfer Martin Laird who was joined on one-under by Ian Poulter.
His fellow Englishmen Gary Christian and Brian Davis were level par.
