Matt Scott had 469 total yards and accounted for four touchdowns, helping Arizona overcome a huge day by Southern California's Marqise Lee to beat the 10th-ranked Trojans 39-36 on Saturday.
Lee caught 16 passes for a Pac-12-record 345 yards and two touchdowns to help USC (6-2, 4-2 Pac-12) build a 15-point lead midway through the third quarter.
But Scott led Arizona (5-3, 2-3) back, throwing for 369 yards and three touchdowns, including a 7-yarder to David Richards that put the Wildcats up 39-28 with just over 5 minutes left.
The Trojans answered quickly with Silas Redd's second rushing touchdown, from 10 yards, but remain stuck on 799 wins as a program after Matt Barkley's last-ditch pass into the end zone was swatted down.
