Sung Kang had a career day at Monterey Peninsula Country Club, shooting a bogey-free 11-under 60, a tournament course record to move into a tie for the lead halfway through the AT&T Pebble Peach Pro-Am. Sitting tied for 81st after the first round at even par, Kang is now even with Hiroshi Iwata.
Phil Mickelson sits tied for third with Freddie Jacobsen and Chez Reavie at 10 under. The four-time Pebble Beach champion shot a 6-under 65 at Monterey Peninsula to move 13 spots up the leader board and to within one shot off the lead. He shot seven-under on his first 10 holes of the round.
"I feel good with the putter. I feel relaxed over each putt," said Mickelson. "I feel like I'm just matching up the line and the speed, and I'm making some. And last week was a bit of a weird anomaly where I felt like I was hitting my line with the right speed, and they weren't quite going in, they were catching lips."
World No. 1 Jordan Spieth sits tied for 36th place at three-under-par, having shot a two-under 69 at Monterey Peninsula. Jason Day, also playing at Monterey Peninsula, shot a five-under 66 to move into a tie for 13th at 6-under.
Justin Rose, playing in the Pebble Beach Pro-Am for just the first time, is in sixth place at 9-under, and two shots off the lead. He shot a 3-under 68 at Monterey Peninsula.
