Jake Luton passed for 328 yards, and Artavis Pierce and Jermar Jefferson each rushed for more than 100 yards in Oregon State's 56-38 win over Arizona in a Pac-12 game Saturday in Tucson, Ariz.

Luton completed 20 of 26 passes with three touchdowns and no interceptions.

Pierce gained 114 yards with a touchdown on 15 carries, and Jefferson finished with 105 yards and three scores on 22 rushes.

Arizona (4-5, 2-4 Pac-12) lost its fourth consecutive game and first with Chuck Cecil as the interim defensive coordinator after his predecessor Marcel Yates was fired last week. Cecil, a former Arizona player who went on to play in the NFL and spend 15 years as an assistant in the league, saw his unit allow 572 yards.

Arizona continued its two-quarterback system with senior Khalil Tate starting and true freshman Grant Gunnell coming in for the third series. Gunnell played most of the second half and engineered three touchdown drives. He completed 19 of 29 passes for 269 yards with two touchdowns and no interceptions.

Tate completed 7 of 12 passes for 109 yards. He came out after failing to lead the Wildcats to points in their last possession of the first half and first coming out of halftime.

Oregon State (4-4, 3-2) never trailed after opening the game with a nine-play, 75-yard drive that ended with a 21-yard touchdown pass from Luton to Isaiah Hodgins. Six of the Beavers' first seven possessions resulted in touchdowns.

Hodgins finished with seven catches for 150 yards.

The Beavers punctuated the first half with a 92-yard drive on seven plays that took only 54 seconds. Luton connected with Noah Togiai for a 23-yard score with 4 seconds remaining until the break.

Oregon State continued to roll in the second half, taking its first possession 65 yards on seven plays to build a 42-19 lead. Jefferson completed the drive with a 5-yard scoring run.

Gunnell helped the Wildcats rally to cut the lead to 42-31 with 3:20 left in the third quarter. Arizona was in position to cut the lead further, going from its 1-yard line to the Oregon State 21 but that possession ended with a missed 39-yard field goal by Lucas Havrisik with 11:16 remaining in regulation.
