Oklahoma State quarterback Drew Mestemaker needed all of one play Saturday to start erasing his (and his team’s) disappointing Week 1 showing in a loss at Tulsa. Mestemaker broke loose for a 75-yard run on the Cowboys’ first offensive snap against Oregon, kickstarting a dazzling performance as he led Oklahoma State — a 24.5-point underdog — to a 39-31 upset of the No. 6 Ducks.Mestemaker, who followed Oklahoma State coach Eric Morris from North Texas this offseason, finished with 317 yards and two touchdowns on 26-of-43 passing, plus added 109 yards and a touchdown rushing.He did throw two interceptions, both on tipped balls, that led to 14 Oregon points in the first half.
