Brandt Snedeker carded a 4-under 68 on Friday to join Ted Potter, Jr. in the lead after two rounds of the Pebble Beach National Pro-Am.
Potter carded his second straight 67, this one a 3-under round on the par-70 Shore Course at Monterey Peninsula Country Club. Snedeker played his second round at the par-72 Spyglass Hills, while the remainder of the field was at Pebble Beach Golf Links, which is also a par-72 course.
The players rotate over the three courses for the first three rounds, while being paired with amateurs. The final round on Sunday will be played at Pebble Beach.
Snedeker, who finished second the last two weeks, and Potter ended two rounds at 8-under-par 134.
Hunter Mahan, who shared the first-round lead with Russell Knox, carded a 1- under 69 at Monterey to slip into a share of third at minus-7. He was joined there by Fredrik Jacobson (66 at Pebble), John Merrick (67 at Monterey) and Patrick Reed (69 at Pebble).
Jason Day (68) and Patrick Cantlay (70) both played Spyglass on Friday and completed two rounds at minus-6. They stand alongside Nick O'Hern (66) and James Hahn (65), who both played Monterey on Friday.
Knox tripped to a 1-over 73 at Spyglass to finish two rounds at minus-5, where he was joined in 11th place by five others.
Defending champion Phil Mickelson is tied for 39th at minus-2 after carding a 1-under 71 at Spyglass on Friday. He had three birdies in a 5-hole span on his opening nine, but bogeyed three of four holes around the turn. Mickelson birdied the par-4 eighth to end in red figures.
Snedeker started on the back nine at Spyglass and carded birdies on the 12th and 14th to move to minus-6. He ran off 10 consecutive pars from the 15th.
The reigning FedExCup champ birdied the par-5 seventh and made it two in a row with a birdie on No. 8 to move into a share of the lead. He parred the last to end there.
"I didn't make a lot of putts today, but look forward to going into the weekend as my confidence is very high, and after last week, I feel like my game is where I want it to be and two good days to go, should be a lot of fun," stated Snedeker. "I take nothing but positives away from the way I've played the weekend the last couple events. I know I'll have a lot of fun this weekend, so just try to recreate that. That's how you win out here. You keep putting yourself in position, and the more times you do, that the more success you're going to have."
Potter, who won the Greenbrier Classic last year, eagled the par-5 10th at Monterey to start his round. After a trio of pars, he stumbled to back-to-back bogeys at 14 and 15.
The 29-year-old rolled in a birdie effort at the second and made it two in a row with a birdie at the third.
Potter moved to 7-under with a birdie on the par-5 sixth. He came right back with a birdie on the seventh and parred his final two holes to share the second-round lead.
Knox was joined at minus-5 by two-time U.S. Open champion Retief Goosen (68 at Pebble), Sean O'Hair (67 at Monterey), Justin Hicks (68 at Pebble), Matt Every (70 at Monterey) and Chris Kirk (68 at Pebble).
NOTES: The cut will take place after the third round and will only be the low 60 and ties, with the top 25 amateur teams moving on the final round as well ... Day and San Francisco 49ers coach Jim Harbaugh lead the pro-am competition ... Former Masters champion Mike Weir fired a 5-under 65 at Monterey and that was his best round since carding a 64 in the second round of the 2010 Honda Classic ... Four of the first five winners this year had at least a piece of the 54-hole lead.
