Marion Grice scored four touchdowns, two on passes from Taylor Kelly, and Arizona State used consecutive big plays in the third quarter to race past Southern California, 62-41, on Saturday night in Tempe, Ariz.
Arizona State (3-1 overall, 1-1 Pacific-12 Conference) trailed by one after USC opened the third quarter with a quick scoring drive.
The Sun Devils ran away from the Trojans after that, scoring a pair of touchdowns 47 seconds apart.
Kelly orchestrated the first, hitting D.J. Foster in stride for a 74-yard touchdown pass. Alden Darby was next, stepping in front of a pass by Cody Kessler for a 46-yard interception return that put the Sun Devils up 34-21.
Tre Madden and Justin Davis each scored three touchdowns for USC (3-2, 0-2).
It wasn’t nearly enough with Arizona State piling up yards while scoring its most points ever against the Trojans and matching the most ever scored against USC.
Behind Kelly and Grice, the Sun Devils racked up 612 total yards against a defense that had not allowed more than 285 yards or 14 points this season. USC allowed 479 yards its previous two games combined.
The nation’s scoring leader coming in, Grice pushed his touchdown total to 12 — 18 the past seven games over two seasons — with catches of 11 and 8 yards along with runs of 9 and 28 yards.
Kelly completed 23 of 34 passes for 351 yards.
Madden had 194 total yards, with two touchdowns receiving, and Davis had 122 yards and three scores on the ground.
Kessler threw for 295 yards and a pair of touchdowns, and Marqise Lee became USC’s career yards receiving leader after catching seven passes for 92 yards. He passed Johnny Morton’s mark of 3,201 yards.
Already with a conference loss each, neither team wanted another; 0-2 would be a huge hill to climb toward a spot in the Pac-12 championship game.
Advantage: Arizona State.
USC looked good early, rolling over the Sun Devils on a pair of scoring drives in the first half. Davis capped the first with a 26-yard run and Madden the second with a 10-yard reception to put the Trojans up 14-7.
But USC closed the first half with a pair of turnovers — an interception on a ball that went off Lee’s hands and a fumble by Madden — to set up Zane Gonzalez field goals.
Settling for field goals looked like it might hurt Arizona State when USC quickly marched down the field for a touchdown to open the third quarter.
Madden’s 24-yard touchdown run put the Trojans up 21-20.
Not much went right after that.
At No. 2 Oregon 55, Cal 16: Marcus Mariota threw for two touchdowns and ran for another in the Ducks’ victory over Bears in the rain-drenched Pac-12 opener for both teams.
Bralon Addison returned two punts for touchdowns, and Byron Marshall ran for 130 yards and two more scores for Oregon (4-0, 1-0).
The game was played as a strong storm swept across the Pacific Northwest, cutting power to more than 26,500 customers in Oregon. It was a sloppy mess on the field, with eight fumbles — four for each team — in the first half alone. The Ducks handled the soggy conditions better, building a 41-3 halftime lead.
The driving wind and rain all but shut down the “Bear Raid” offense that new head coach Sonny Dykes has installed at Cal (1-3, 0-1).
Mariota completed 11 of 24 passes for 114 yards and ran for another 33 yards before coach Mark Helfrich sat him during the third quarter.
At Oregon State 44, Colorado 17: Sean Mannion passed for 414 yards and a school-record six touchdowns, and the Beavers (4-1, 2-0) won their fourth consecutive game with the victory over the Buffaloes.
Brandin Cooks caught nine passes for 168 yards and two touchdowns for Oregon State, and had five carries for 47 yards.
Mannion battled gusty winds to complete 27 of 52 passes. The OSU junior leads the country with 2,018 passing yards and 21 touchdown passes.
Caleb Smith also caught two TD passes for the Beavers, who never trailed.
Colorado (2-1, 0-1) played its first game in three weeks. Flooding postponed the Buffaloes’ Sept. 14 game against Fresno State, in addition to a bye week.
