Oregon State forced four turnovers, Damien Martinez put forth another 100-yard rushing performance, and Oregon State blew the doors off Colorado to move to 6-2 on the season.

The Beavers, who won 42-9, are off to their best start since 2013. They’re already bowl eligible, which means coach Jonathan Smith will have Oregon State bowling for a second consecutive season for the first time in a decade.

For the second week in a row, freshman running back Damien Martinez looked like the back we all heard about in the offseason. Martinez ran over Colorado for 178 yards and three scores. He opened the scoring in the first quarter with a 4-yard score, and he closed the game out with a 4-yard fourth-quarter score.

OSU scored on three of its five first-half possessions and then put the game to bed in the first two minutes of the third quarter. Quarterback Ben Gulbranson hit tight end Jack Velling on a 60-yard pass up the seam for a score on the fourth play of the second half, putting the Beavers up 28-3. Velling shrugged off a poor attempted tackle from Colorado and rumbled in for the score — one of two from Gulbranson on the evening.

On the very next play, Alex Austin stepped in front of a JT Shrout pass and returned it 42 yards to the house.

Shrout, making his third start of the year for the injured Owen McCown, completed 13 of his 29 pass attempts for 206 yards and two interceptions. Three of Colorado’s five second-half possessions ended in turnovers, with another lasting only three plays and netting a loss of 2 yards before punting back to Oregon State.

There was a brief moment in the first quarter when it looked like Colorado might be able to build some momentum. Gulbranson fumbled the first play from scrimmage for the Beavers, a mishandling of the snap, that Colorado recovered. It set the offense up on Oregon State’s side of the 50.

Three plays later, CU fumbled the ball and gave it right back to Oregon State, which went 40 yards in nine plays to score the game’s opening touchdown.

The win marked the first time since a 21-7 win over Utah in 2012 that the Beavers held a Pac-12 opponent under 10 points. With the running game getting rolling and the defense really starting to control things, Oregon State might be hitting its stride again. The Beavers head into the bye week with a 3-2 record in conference play. They’ll face Washington on Nov. 4.

Colorado (1-6, 1-3 Pac-12) returns home next Saturday for a 4:30 p.m. PT (ESPNU) tilt against Arizona State.
