Bridgford finished 9 for 21 for 113 yards, one touchdown and two interceptions.
"We felt like at halftime we were going to win the game," Bridgford said. "The second half they pulled away a little bit, but we had our chances. We beat ourselves."
Mariota left the game holding his left arm in the second quarter but returned after Vincenzo D'Amato missed a 48-yard field goal late in the half for Cal. Mariota drove the Ducks 69 yards, capped by a 10-yard pass to Huff that made it 24-10 at the half.
