Oregon State defeated Washington State 10-7 in Week 10, covering the 3-point spread in a defensive showcase that stayed well under the 47.5-point over-under. The Beavers scored a field goal in the second quarter and added a touchdown in the fourth, while the Cougars managed their only score—a touchdown—in the second quarter.

Washington State's offense, led by quarterback Z. Eckhaus, struggled against Oregon State's defense throughout the game. The Cougars' most impactful play came early in the first quarter when Eckhaus connected with T. Freeman on a 26-yard completion, but that momentum couldn't be sustained. Oregon State's defense delivered the game's biggest play in the second quarter when J. Patterson intercepted Eckhaus and returned it 36 yards. The win probability data showed significant swings, with 24 lead changes during the contest. Gabarri Johnson paced Oregon State with 33 passing yards, while Washington State's Josh Meredith led all receivers with 44 yards. The defensive battle remained tight throughout, befitting the modest final margin.
