Drew Mestemaker came out of the locker room at West Virginia down 21-13 and completed 11 of 14 passes for 274 of his 389 yards after halftime, finishing with three touchdowns and one interception. Wyatt Young ran past the Mountaineer secondary for gains of 50, 48 and 48 yards on his way to 192 receiving yards, the most by an Oklahoma State player since 2021. Oklahoma State scored 28 of the game's final 31 points and won 41-24 on the road, in a conference game, in September.
The offense had been waiting since August for a night like that. Tulsa, Oregon and Murray State all told you something, but none of them told you whether Eric Morris's North Texas system would hold up against a Big 12 defense that had a plan for it. Now one has tried, and Oklahoma State put up 609 yards.
What the win actually ends
The streak numbers are the part to sit with. This was Oklahoma State's first Big 12 win since 2023, ending an 18-game conference losing streak and an 11-game road skid. Three years ago this program went 10-4 and played in the Big 12 Championship Game; it followed that with 3-9 and 1-11 seasons, going 0-9 in conference play in both. Mike Gundy's 21-year tenure, a Big 12 title, eight 10-win seasons, a school-record 170 victories, ended in September 2025, and Morris inherited the wreckage of what came after it. A 3-1 start with a road conference win is not a restoration. It is the first evidence that one is possible.
The model still projects roughly three Big 12 wins against six losses, with Colorado at home in Week 8 the only game on the remaining schedule where Oklahoma State is favored, at about 61 percent. UCF in the Week 6 home opener of the conference stretch sits near 38 percent, and Kansas in late November at 41 percent. The full board is at the interactive guide, and the simulation details at methodology.
The parts that aren't settled
Oklahoma State trailed 14-3, then 21-13. It committed nine penalties for 89 yards. It let West Virginia convert 9 of 17 third downs and gain 466 yards. Mestemaker threw a pick. A clean wire-to-wire Big 12 performance still hasn't happened, and the opponents get harder from here. Iowa State, Kansas State and Texas Tech all sit under 10 percent in the projections.
What makes the second half more than a hot streak is that the coaching staff caused some of it. Oklahoma State moved away from the three-down front it had opened in at halftime, and head coach Eric Morris described the effect as playing "a lot more free," with everybody settled down, calling it a good adjustment by Skyler Cassity. Ethan Wesloski added half a sack; Tate Romney added 12 tackles, a sack and two tackles for loss.
The newcomers are settling into their jobs, too. Mose Phillips III, elevated to starting free safety on the Week 4 depth chart in place of Evan Jackson, intercepted a pass in his first start there, part of a night that also produced four sacks and eight tackles for loss. Chris Barnes, who missed the Murray State game with a shoulder injury from the Oregon win, was back in the receiving rotation.
Left tackle is answered
Morris later confirmed Sexton was out for the year. Shaun Torgeson, the Portland State transfer, was named the starter at left tackle for the Oregon game, and by West Virginia week the "OR" was gone from the depth chart entirely. Torgeson was listed outright, with Desmond Magiya, the emergency Week 1 fill-in, as a backup left guard. Then West Virginia's Rich Rodriguez said after the game, "We never got any pressure" on Mestemaker, adding that when you don't pressure a player like that, he beats you.
That is the opposing head coach describing a rebuilt line with a first-year starter at the most important position on it. For a fan who has watched this program shuffle linemen for three weeks, that matters more than any single stat.
Oklahoma State is idle in Week 5. There's no scoreboard worth chasing, no conference result that moves the Cowboys' November math in any way you'd feel. That has not been true in Stillwater for a while.
