Wimberly went 18 yards on Rohach's first play, but that was the only first down before a quick 17-point burst to finish the half by the Bears, who came in leading the nation at 715 yards and 63 points per game.
The spurt started with Seastrunk's weaving 48-yard run up the sideline to set up his own 2-yard plunge and finish a 94-yard drive in eight plays that took just 1:52. After a three-and-out from Iowa State, Petty found Goodley wide open in the middle of the field for a 36-yard touchdown on fourth-and-6.
The Bears got the ball back at their 32 and went 34 yards in 23 seconds without a timeout on three straight passes from Petty to Goodley, who had nine catches for 138 yards in the first half. Jones kicked a 51-yard field goal on the final play of the half.
Richardson and Rohach ended up splitting the playing time for Iowa State. They combined for just 133 yards passing with an interception apiece and five sacks between them. Richardson went down three times, and Baylor had 10 tackles for loss.
The Cyclones finished with just 41 yards rushing because they had 47 yards in losses. They had 174 yards total offense, with 57 coming on the late scoring drive.
"It was very apparent, the first two drives nerves kind of got to me," Rohach said. "As the game went on, I got more reps, they slowed down for me, which is nice. I didn't like the outcome."
