Jake Luton passed for 255 yards and four touchdowns, leading Oregon State to a 45-7 victory over Cal Poly on Saturday at Reser Stadium.

Luton, who was coming off a subpar performance in last Saturday's 31-28 loss at Hawaii, was on target from the outset against the Mustangs. The sixth-year senior completed 17 of 22 passes.

The win snapped a six-game losing streak for the Beavers (1-2).

Luton threw all four of his touchdown passes in the first half, including 47- and 75-yard strikes to diminutive wide receiver Champ Flemings. He played one series in the third quarter before giving way to backup quarterback Tristan Gebbia.

The Mustangs (1-2), who lost 41-24 last week at Weber State, played a Pac-12 school for the second time in school history.

OSU sophomore running back Jermar Jefferson, who came into the game ninth nationally in rushing (127 yards per game), did not play due to a foot injury. B.J. Baylor led the Beavers ground game with 101 yards on seven carries, including a 74-yard scamper in the third quarter. Artavis Pierce got the start and added 90 yards on 12 carries.

The Beavers did a solid job defending Cal Poly's triple option, holding the Mustangs to 315 total yards. Cal Poly averaged 467.5 yards and 38 points in its first two games, albeit against lower-division competition. OSU sacked quarterback Jalen Hamler three times and recovered a fumble on one of the sacks.

Duy Tran-Sampson led the Mustangs with 137 yards on 29 carries.

OSU took the opening kickoff and marched 74 yards in six plays, with Luton hitting Isaiah Hodgins for an 8-yard touchdown.

Cal Poly answered on its first possession. Hamler connected with wide receiver J.J. Koski on a 53-yard strike, setting up an 8-yard touchdown pass to running back Xavier Moore.

Hodgins' 11-yard touchdown reception on the ensuing possession put the Beavers back in front at 14-7 with 5:39 left in the first quarter.

OSU increased its lead to 21-7 late in the first quarter on Baylor's 6-yard run. On the final play of the opening quarter, linebacker Hamilcar Rashed Jr. sacked Hamler and forced a fumble that was recovered by linebacker Omar Speights at the Mustangs' 21-yard line. That led to a 26-yard field goal by Jordan Choukair.

Flemings' 47-yard touchdown reception increased the lead to 31-7 late in the second quarter, and the diminutive On sophomore got past Cal Poly's secondary for a 75-yard touchdown catch with 21 seconds left in the first half to give the Beavers a 38-7 lead at the break.

OSU, which amassed 549 total yards, played reserves most of the second half.

It was the first meeting between OSU and Cal Poly.
