TUCSON, Ariz. (AP) - Caleb Love hit a tying heave from beyond halfcourt at the end of regulation and made two more 3-pointers in overtime, finishing with 22 points and lifting Arizona to an 86-75 win over No. 3 Iowa State on Monday night.

The Cyclones (17-3, 7-2 Big 12) appeared to be in control when Joshua Jefferson hit one of two free throws with 2.2 seconds remaining, but they left too much time on the clock.

Love, who was 1 for 10 on 3s at that point, took a couple of dribbles and drained his shot from behind the midcourt logo, sending a roar through McKale Center.

Love then hit two corner 3s in overtime and Carter Bryant added another to cap Arizona's first win at home over a top-5 opponent as an unranked team since beating No. 3 UCLA in 1979.
