Pullman, WA -- (Sports Network) - Yvenson Bernard ran for a game-high 74 yards and two touchdowns as the Oregon State Beavers crushed the Washington State Cougars, 52-17, in Pac-10 Conference action at Martin Stadium.

The Beavers (7-4, 5-3 Pac-10) rolled up 218 yards and six touchdowns on the ground, while Lyle Moevao converted 15-of-28 passing for 202 yards and a score as well.

The Cougars (4-7, 2-6) were led by Kevin McCall who carried the ball 14 times for 62 yards and a pair of scores. Quarterback Alex Brink hit 21-of-45 for 314 yards, but he was sacked twice and picked off an incredible six times in the lopsided finish.

OSU ran out to a quick 21-0 lead in the first quarter as Moevao scored on a one-yard touchdown run, Bernard found the end zone on an 18-yard jaunt and James Rodgers added an eight-yard TD run.

The only scoring for Washington State in the first half came courtesy of kicker Romeen Abdollmohammadi who knocked through a 40-yard field goal with 13:33 remaining in the second period.

Before the half could draw to a close, Oregon State posted another 10 points on a 22-yard field goal by Alexis Serna and a two-yard TD run by Bernard to make the score 31-3 at the break.

In the third quarter McCall's 19-yard touchdown run for the Cougars cut slightly into the deficit, but the Beavers came right back with a seven-yard TD run by Matt Sieverson to give OSU a commanding 38-10 advantage heading into the fourth.

McCall's one-yard touchdown run moments into the fourth was the last time WSU would come close to making the game respectable as Oregon State ripped off another two touchdowns, the first a 56-yard run by Clinton Polk and the next a one-yard pass from Moevao to Howard Croom.

In addition to limiting the home team to just 4-of-15 on third down and holding the Cougars to less than 25 minutes of possession, the Beavers scored on all seven of their red zone opportunities and made good on 10-of-21 on third down.
