Joshua Jefferson scored 24 points and No. 4 Iowa State overcame a 13-point deficit to stay unbeaten with a 66-62 win over Iowa on Thursday night.
The Cyclones (10-0), who entered leading the nation in field-goal percentage after a 23-point victory at then-No. 1 Purdue, were sluggish early. But a 19-0 run spanning both halves gave them the lead, and they held off a late surge by Iowa (8-2) to win their third straight in the CyHawk Series.
Tamin Lipsey had 14 points and four assists, and Milan Momcilovic scored eight of his 10 points in the second half.
