BIG 12 ROUNDUP

Iowa State 48, No. 25 Oklahoma State 42: Thirdstring quarterback Brock Purdy completed 18 of 23 passes for 318 yards and four touchdowns to help lead visiting Iowa State (2-3, 1-2 Big 12 Conference) to a win. He also had a rushing touchdown. Tyler Cornelius was 19 of 33 passing for 289 yards and four touchdowns for Oklahoma State (4-2, 1-2), which lost its second consecutive home game. The Big 12’s leading rusher, Justice Hill, was limited to 66 yards and one touchdown on 24 carries, a 2.8-yard average.

Purdy, a true freshman, had played just one series before this game. But he stepped in for Zeb Noland – who was starting his fourth straight game in place of injured starter Kyle Kempt – in the contest’s second series and immediately sparked Iowa State.

The Cyclones entered the day ranked last in the Big 12 in both scoring (17.5 points per game, 122nd in the nation out of 130) and yards (299.5 per game, 123rd overall) but reached season highs in both categories, amassing 465 yards overall.

No. 9 West Virginia 38, Kansas 22: Will Grier threw four touchdown passes, and committed four turnovers, for host West Virginia (5-0, 3-0 Big 12), which has won its first five games for the second time in three seasons.

The heavily-favored Mountaineers had no trouble moving the ball but Grier’s efforts to throw into tight coverage near the goal line cost his team plenty of points. The Heisman Trophy hopeful was intercepted three times in the first half either in the end zone or at the goal line, two of them by cornerback Hasan Defense. Kansas (2-4, 0-3) entered the game leading the Big 12 with eight interceptions.

Baylor 37, Kansas State 34: Connor Martin kicked a 29-yard field goal with eight seconds left to give host Baylor (4-2, 2-1 Big 12) a victory over Kansas State (2-4, 0-3). Martin missed three field goals and an extra point, but his third made field goal in the game counted the most for Baylor
