Matt Jones and Brandt Snedeker are tied for the lead at the halfway point of the AT&T Pebble Beach National Pro-Am.
Jones fired five birdies and dropped just one stroke in the first nine holes to reach the turn in 32 before picking up further shots at the 11th and 13th.
Despite bogeying the penultimate hole, the Australian birdied the last to card a 66 and join Snedeker at 12-under-par.
Snedeker moved up the leaderboard after an error-free round of 67 on the Spyglass Hill course, with the pair one stroke ahead of Justin Hicks, while 10 players are tied for fourth place, a shot further back.
John Daly failed to build on his impressive first round as he could only muster a level-par 72.
