MORAGA, Calif. (AP) _ Sal Rivas kicked three field goals, including a 35-yarder in the fourth that proved the game-winner as Cal Poly-SLO held off St. Mary's 24-21 on Saturday.

Cal Poly (3-7) trailed 7-6 at the half, and St. Mary's (2-9) took a 14-6 lead in the third on a 5-yard scoring strike from Gus Papanikolas to Eric Billeci.

But Cal Poly tied the game on Ryan McCarty's 17-yard run and a two-point conversion, then increased the lead to 21-14 in the fourth.

Rivas' field goal put the Mustangs up for good with 2:59 remaining and although the Gaels scored on a 35-yard pass to Marc Kleiman, they could get no closer.

Jepson was 20-of-31 for 176 yards, and Craig Young rushed for 132 yards on 13 carries before leaving the game late in the second quarter with a knee injury.

Kleiman caught six passes for 152 yards and one score for St. Mary's.
