Stanford, CA (Sports Network) - Josh Nunes had big shoes to fill in place of No. 1 draft pick Andrew Luck.
The senior delivered in a big way Saturday by hitting Zach Ertz with the go- ahead 37-yard touchdown pass early in the fourth quarter, lifting 21st-ranked Stanford to a 21-14 victory over No. 2 Southern California.
Nunes threw for a pair of scores and Stanford's defense put constant pressure on Matt Barkley, sacking him twice in the final minute.
Ranked No. 1 to begin the season with national title hopes, the Trojans (2-1, 0-1 Pac-12) were unable to hold onto a halftime lead and were shut out in the second half. It's the first time Stanford (3-0, 1-0) has beaten the Trojans four straight times. That includes a triple-overtime thriller last year and on the final play in 2010.
Stepfan Taylor rushed 27 times for 153 yards and a pair of touchdowns for the Cardinal, but it was Stanford's defense that stepped up big time by holding to Trojans to 1-of-13 on third down conversions.
Nunes connected on 15-of-32 throws for 215 yards and was intercepted two times.
Barkley completed 20-of-41 passes for 254 yards and was picked off twice.
