Jayden Nunn made the go-ahead layup with 2 seconds remaining and 18th-ranked Baylor overcame coach Scott Drew's first career ejection to beat No. 12 Iowa State 70-68 on Saturday night. The Bears hung on for the victory when Milan Momcilovic's banked 3-pointer by the Cyclones was ruled to be shot after the final buzzer. Nunn finished with 16 points and RayJ Dennis had 18 points and seven rebounds for Baylor (16-5, 5-3 Big 12), which was back at home a week after a triple-overtime loss to TCU.
