Ronnie Black shot a 6-under 66 at Del Monte Golf Course on Friday to take a one-stroke lead over Joel Kribel after the second round of the Callaway Golf Pebble Beach Invitational.
Black, the 1995 winner, had a 10-under 134 total in the tournament that includes players from the four major tours as well as mini-tour players, club pros and amateurs.
After an opening 68 at Pebble Beach, Black had five birdies, an eagle and a bogey at Del Monte, the easiest of the three courses featured in the 36th annual event.
"It's exciting, but it doesn't do much for you at the halfway point," said the 49-year-old Black, who won the last of his two PGA Tour titles in 1984.
"It's nice, but it's just bragging rights," he said.
Kribel, a farmer PGA Tour regular who played on the Nationwide Tour this season, shot a 69, also at Del Monte. Kribel earned a position in the tournament with his win three weeks ago in the unofficial Monterey Open.
Kevin Sutherland, who shot a tournament-low 62 in the opening round, was third at 8 under after a 74 at Spyglass.
"I didn't play all that well," said Sutherland, the 2000 tournament winner. "I had my opportunities a little bit, but I just didn't hit enough good shots."
Tom Purtzer shot a 69 at Spyglass Hill for a 7-under total, the lowest among eight Champions Tour participants.
Leta Lindley led the seven LPGA Tour players, shooting a 71 at Spyglass Hill for a 5-under total.
Andy North, the two-time US Open winner, withdrew during the second round because of a knee injury.
The top 32 pros and ties and top 10 amateur teams and will qualify for the final round at Pebble Beach. The winner will earn US$60,000 from the US$300,000 purse.
