The ISU football team kept its game in Norman, Okla., close throughout the first half, but the Sooners ran away from the Cyclones in the latter 30 minutes and crossed the finish line with a blowout win, 52-16.

Iowa State (3-6, 2-4 Big 12) trailed No. 15 Oklahoma (8-1, 5-1 Big 12) by a score of 21-9 coming out of the locker room, but OU quarterback Baker Mayfield and company proved too much for the Cyclones to handle.

Mayfield threw for 342 yards and three touchdowns as the Sooners amassed 684 yards of total offense. The ISU defense’s performance, particularly in the second half, stood in stark contrast with the team’s shutout of Texas at home the previous weekend.

The Cyclones afforded the Longhorns only 204 total yards in that game. Saturday in Oklahoma, Iowa State allowed 279 yards rushing alone.

The ISU offense struggled as well, despite holding the ball for 7 minutes and 4 seconds longer than Oklahoma. Running back Mike Warren failed to eclipse 100 yards on the ground for only the second time in seven starts this season, finishing the day with 43 yards on 18 carries.

The redshirt freshman, on his way to becoming the first ISU running back to rush for 1,000 yards since 2009, finished three yards shy of that milestone Saturday.

The one offensive bright spot for the Cyclones was wide receiver Allen Lazard, who pulled in eight catches for 101 yards.

Iowa State returns to Ames for its final home game of the year next Saturday against No. 14 Oklahoma State, which ended No. 8 Texas Christian’s bid at perfection, defeating the Horned Frogs, 49-29, in Stillwater, Okla.
