PGA Champion Keegan Bradley and Brendan Steele teamed for a 10-under 62 on Saturday to take the second-round lead of the Franklin Templeton Shootout.
Bradley and Steele, first-round co-leaders, finished at 19-under 125 and are shot clear at the Gold Course at Tiburon Golf Club.
Bradley and Steele shared Friday's lead with the Champions Tour pair of Mark Calcavecchia and Nick Price. Those two teams will be in Sunday's final group again. Calcavecchia and Price overcame a bad start with a nine-under 63 and are second at minus-18.
Bradley and Steele, both rookies, combined for three wins on the PGA Tour this year. Bradley's biggest victory came at the PGA Championship, where Steele was the third-round leader.
Calcavecchia and Price both won on the Champions Tour this season. They've combined for two British Open titles and had fun playing with their much younger peers on Saturday.
"It's enjoyable playing with those two kids," Calcavecchia said in a televised interview. "I've always enjoyed coming to play. This is fun. We're in the last group tomorrow."
Rory Sabbatini and Jhonattan Vegas fired Saturday's lowest round, a 12-under 60, and are third at minus-17.
