Lake won his debut taking over for Chris Petersen, who stepped away from coaching after last season. The debut was delayed after last week’s game at California was canceled due to COVID-19 concerns with the Golden Bears.
Peyton Henry kicked a 23-yard field goal with 1:45 left, the only points scored in the second half by either team.
Jermar Jefferson rushed for 133 yards and a TD for Oregon State, his 12th career 100-yard rushing game. But Jefferson was stopped twice needing less than a yard from the Washington 5 early in the fourth quarter and the Beavers (0-2 Pac-12) on the cusp of taking the lead.
