CORVALLIS, Ore. (AP) Damien Martinez ran for 146 yards and a career-high four touchdowns to lead No. 12 Oregon State to a 62-17 victory over Stanford on Saturday.
Martinez, the Pac-12 freshman Offensive Player of the Year last year, surpassed 1,000 yards for the season and did most of his damage in the first half with 136 rushing yards and all four touchdowns, including a 59-yard score in the first quarter.
The Beavers (8-2, 5-2 Pac-12, No. 12 CFP) kept their Pac-12 championship game hopes intact and extended their home winning streak to nine games.
Stanford (3-7, 2-6), which was coming off a 10-7 win at Washington State and played No. 5 Washington close at home two weeks ago, couldn't keep up with the Beavers' big-play offense.
While Martinez set the tone, Oregon State was by no means one-dimensional offensively.
DJ Uiagalelei completed 12 of 19 passes for 240 yards and two touchdowns.
The Beavers' defense was led by end Andrew Chatfield Jr., who had two sacks, a forced fumble and an interception.
A 61-yard catch and run by wide receiver Anthony Gould set up Martinez's third touchdown of the first half, a 15-yard run for a 21-7 lead early in the second quarter.
A 40-yard touchdown pass to wide open tight end Jermaine Terry II extended the lead to 28-7 at 10:17 of the second quarter.
Martinez scored again from 5-yards out with 15 seconds left in the second quarter to give the Beavers a 34-10 lead at halftime.
Deshaun Fenwick scored a 13-yard touchdown reception on the opening drive of the third quarter for a 41-10 lead.
Stanford quarterback Ashton Daniels ran for a 7-yard touchdown late in the first quarter, cutting the lead to 14-7.
Stanford returns home for the 126th Big Game against Cal next Saturday.
