Mat Mladin battled Miguel Duhamel early on but then pulled away to win the first AMA Superbike race of the weekend at Infineon Raceway in Sonoma, California.

Duhamel faded to 3rd behind a charging Aaron Yates.

Eric Bostrom was 4th ahead of Ben Bostrom, Steve Rapp, Kurtis Roberts and Larry Pegram.

Jason Pridmore, who had caught and passed Ben Bostrom, ran out of fuel on the last lap and pushed his bike across the line in 9th.

Lee Acree was 10th ahead of Jordan Szoke, Vincent Haskovec, Steve Crevier, John Dugan and Jeremy Toye. Haskovec was the last rider on the lead lap.

Rapp came from row 11 on the grid while Acree came from row 10.

Complicating things was a light drizzle on parts of the track mid-race.

Anthony Gobert pulled off the track and parked his Ducati against a barrier, while running behind Rapp, a little after the halfway point.
