LAWRENCE, Kan. (AP) — Freshman Ben McLemore had a career-high 33 points, including a tying 3-pointer with a second left in regulation, and No. 6 Kansas rallied to beat Iowa State 97-89 in overtime Wednesday night.

McLemore was 10 of 12 from the field and perfect on six 3-pointers for the Jayhawks (13-1, 1-0 Big 12), who scored the first nine points of overtime to wrap up their 12th straight win.

Iowa State (10-4, 0-1) poured in 14 3-pointers, and had forged a 79-76 lead with 8.4 seconds left in regulation. But the Jayhawks’ Elijah Johnson found McLemore on the wing, and he banked in a 3-pointer from well beyond the arc with a single tick on the clock to force overtime.

McLemore added another 3-pointer to open the extra 5 minutes, and Travis Releford and Jeff Withey made five consecutive free throws to help put the game away.
