STANFORD, Calif. — Chase Thomas intercepted a tipped pass by Matt Scott in overtime, Stepfan Taylor ran for a 21-yard score two plays later, and No. 18 Stanford rallied from a two-touchdown deficit to stun Arizona 54-48 on Saturday.

Josh Nunes threw for a career-high 360 yards and two touchdowns and ran for three more scores for Stanford (4-1, 2-1 Pac-12) to offset Scott's record-setting performance.

Scott completed 45 of 69 passes — both school records — for 491 yards and three touchdowns until Henry Anderson tipped his final pass in overtime that Thomas intercepted. Arizona (3-3, 0-3) amassed 617 total yards but lost for the third straight game and is still winless in conference play.

For most of the afternoon, the Wildcats scored at will and looked more like the team that beat Oklahoma State to start 3-0 than the one that lost to Oregon and Oregon State the previous two weeks. Facing its third straight ranked opponent, Arizona's aerial attack shredded Stanford's defense in a way few teams have the past few seasons.

The Wildcats became the first team to eclipse 400 yards passing against the Cardinal since Oklahoma in the 2009 Sun Bowl.

Nunes ran his second 1-yard touchdown to trim Arizona's lead to 48-41 with 6:34 remaining.

The redshirt junior ran for 16 yards on third-and-seven from midfield, threw 17 yards to tight end Zach Ertz on fourth-and-nine from Arizona's 20, and ran for the tying touchdown with 45 seconds remaining.
