The three first-round co-leaders were unable to keep the momentum going in Friday's second round. But while Paul Casey and Brendon de Jonge remain in serious contention, Shaun Micheel will definitely have to make up ground if he wants to move back up the leaderboard.
Casey and de Jonge each shot second-round 2-over 73s Friday at Pebble Beach, leaving them at even par for the tournament after their opening 69s.
Meanwhile, Micheel stumbled to a 6-over 77 and is now 4 over for the tournament. Not a bad spot, but he'll have to climb over a lot of players now.
For Micheel and Casey, the difference came on the greens. On Thursday, each putted wel on firm, dry greens. On Friday, however, they failed to find the touch on softer, moist greens.
Micheel needed just 22 putts in the first round, fewest in the field. On Friday, he needed 32 putts.
Casey needed just 23 putts on Thursday, but 30 putts on Friday.
Micheel, whose only PGA TOUR win came in the 2003 PGA Championship, had an early birdie at the 11th -- he started his round off the 10th tee -- but gave back the stroke at the par-5 14th.
After making the turn, he started his final nine with three consecutive bogeys and ended it with two more.
Casey managed to produce his 73 despite suffering a triple bogey at the par-5 14th. He hit just six greens in regulation for the second straight day but rallied back with a handful of birdies to avoid disaster.
For de Jonge, the round looked promising when he birdied hole Nos. 12 and 13, But then the rollercoaster started. He bogeyed the 14th, birdied the 15th, then bogeyed three of the next four holes and never produced another birdie.
