Cornerback Nohl Williams’ second interception of the game, with 2:13 left on the clock, clinched Cal’s 21-14 upset victory at Auburn in front of a capacity crowd of 88.043 fans at Jordan-Hare Stadium on Saturday afternoon.

Williams, whose 80-yard kickoff return keyed the Bears’ 31-18 win over UC Davis a week earlier, stepped in front of receiver Cam Coleman and picked off Payton Thorne’s pass at the Cal 44-yard line.

The Bears (2-0), nearly two-touchdown underdogs, avenged a 14-10 loss to the Southeastern Conference team from a year ago in Berkeley. Cal thought it was the better team last season and there was little doubt about that in this one.

The Bears led 14-7 at halftime on the strength of two touchdown passes from Fernando Mendoza to redshirt freshman wide receiver Nyziah Hunter.

The Bears, playing without four offensive starters and with star running back Jaydn Ott slowed by a week-old ankle injury, got a spectacular effort from its defense against the Tigers (1-1), who scored 73 points in their opening game.

Linebacker Teddye Buchanan had 11 tackles including two sacks, and forced a key Auburn fumble. Cal forced five turnovers, one more than a year ago against the Tigers.

The difference was the Bears played turnover-free football, led by Mendoza, who was 19 for 21 passing in the first half and finished with 233 yards.
