Jason Kokrak, Kyle Thompson lead

PEBBLE BEACH, Calif. -- Jason Kokrak, a two-time winner this year on the Nationwide Tour who is set to join the PGA Tour next season, shot a 3-under 69 on Friday at Spyglass for a share of the lead with Kyle Thompson in the Callaway Golf Pebble Beach Invitational.

Thompson followed his opening 64 with a 70 at Del Monte to match Kokrak at 10-under 134.

"I hit the ball really well," said Kokrak, who had five birdies and two bogeys. "But I could have shot six or seven strokes (under) if I could have putted the ball better."

Thompson, who next season will rejoin the PGA Tour full-time after a four-season absence, had five birdies and two bogeys.

"It's a tough course and it was tough to make putts out there," said Thompson, who had a hole-in one in the opening round and played Del Monte for the first time in his career in the second round. "Other than that, I hit the ball well."

PGA Tour veteran Cameron Tringale, who carded a 67 at Del Monte, and Matt Battencourt, a two-time PGA Tour winner who shot 68 at Spyglass, were tied for third at 8 under. Harrison Frazar was another stroke back after a 68 at Pebble Beach.

PGA Tour veterans Chez Reavie (67), Kevin Sutherland (68) Blake Adams (69) and Jeff Gove, a three-time Nationwide Tour winner whose 66 at Del Monte was the day's low round, are tied at 6 under.

Defending champion John Mallinger had a 76 at Del Monte to finish at 6 over.

Leta Lindley, who had a 72 at Spyglass en route to a 1-over total, paced the eight LPGA entrants.

Russ Cochran, the reigning U.S. Senior Open titlist, had a 70 at Del Monte and led the 10 Champions Tour entrants at 142.

The event is the only tournament that features head-to-head competition among players from the PGA Tour, LPGA Tour, Champions Tour and Nationwide Tour.

The top 40 pro scores and ties among the 83 pros will advance the final round Sunday at Pebble Beach. The winner will earn $60,000 of the $300,000 purse in the event's 40th edition.
