AMES, Iowa (AP) - Backup quarterback J.W. Walsh threw a 7-yard touchdown pass to Jeff Carr with 3:06 left Saturday, giving No. 5 Oklahoma State a 35-31 victory over Iowa State and keeping the unbeaten Cowboys in playoff contention.
Oklahoma State (10-0, 7-0 Big 12) trailed 24-7 and 31-21 before rallying for a victory that was short on style points but still critical.
Walsh drew the Cowboys to 31-28 with a 16-yard touchdown run early in the fourth quarter and OSU drove 84 yards in 11 plays for the winning score after forcing a punt.
Starter Mason Rudolph got Oklahoma State to the Iowa State 7 and Walsh, usually the team's running quarterback, took it from here. He hit Carr with a swing pass on the left side and two blocks sprung the freshman to the end zone.
