No. 21 Stanford upset No. 2 USC on Saturday, marking the fourth consecutive time that they've beaten the Trojans in the series. USC opened the scoring when Silas Redd ran the ball in from a yard out in the first, but Stanford would respond immediately with a 59 yard Stepfan Taylor touchdown run of their own.

USC opened the second quarter with another scoring drive capped by a Redd touchdown, and that would cap the scoring for the first half.

Taylor would level the game in the third quarter as he took a screen pass 23-yards for the score. Josh Nunes then found Zach Ertz for the winning score midway through the fourth quarter, and the Stanford defense would hold on for the victory.

Matt Barkley had a rough night for the Trojans, completing just 20 of his 41 pass attempts and throwing a pair of interceptions. USC struggled on the ground as well, as Curtis McNeal and Silas Redd combined for only 54-yards of rushing on the night.

Stanford ran the ball very well, with Stepfan Taylor amassing 153-yards on the ground.

USC will be back in action next weekend, as the California Golden Bears make the trip to Los Angeles. The game will kick off at 6:00 p.m. ET and will be carried on the Pac-12 network. The Cardinal have next Saturday off, their next game will be a trip to Century Link Field to face the Washington Huskies on Thursday Sept 27.
