Nick Wilson ran for 218 yards and three touchdowns as No. 15 Arizona overcame an injury to quarterback Anu Solomon to beat No. 20 Utah 42-10 on Saturday.
In heavy rain at times, Wilson topped the 1,000-yard mark this season.
Arizona (9-2, 6-2 Pac-12) reached nine wins for the first time since its 1998 Holiday Bowl team went 12-1 and was ranked No. 4. The Wildcats retain slim hopes for a berth in the conference championship game as a matchup with rival Arizona State looms next week.
The Wildcats ran for 298 yards, the most allowed by Utah (7-4, 4-4) this season.
Solomon threw for 58 yards and got his first career rushing touchdown in the first half. He was fitted for a walking boot at halftime because of an apparent injury to his right foot.
Arizona backup quarterback Jesse Scroggins only threw five times, completing three.
