The Wisconsin team of Steve Stricker and Jerry Kelly are alone in third at eight-under 64. Rickie Fowler and Camilo Villegas combined for a seven-under 65 and are fourth at the Gold Course at Tiburon Golf Club.
This three-round unofficial event started with a modified alternate-shot format on Friday. In round one, each player on the team hits a drive, the best drive is used and the golfer whose drive wasn't picked plays the second shot. The two alternate shots until the ball is holed.
Tournament host Greg Norman and Scott McCarron, who replaced Fredrik Jacobson this week, only managed a three-under 69 and are 11th. Stewart Cink and Bo Van Pelt shot a two-under 70 and are last in the 12-team field.
