Iowa State vs. Oklahoma: Live Score, Highlights and Reaction

The Iowa State-Oklahoma games have been some of the best in the Big 12, if not the country, over the past few years. Saturday's version was no different, and it helps set up a rare No. 1-vs.-No. 2 game on Monday.

Third-ranked Oklahoma rallied from down six midway through the second half to pull out an 87-83 home victory over 11th-ranked Iowa State, remaining unbeaten ahead of Monday's trip to No. 2 Kansas.

The visiting Cyclones (11-2, 0-1 Big 12) led 41-37 at halftime and were up 68-62 with 10:47 left. They led 73-68 before Oklahoma (12-0) went on a 13-4 run to lead 81-77 with 4:19 to go.

The Sooners' run was paced by Isaiah Cousins, who went scoreless in the first half but had 15 points after halftime. Buddy Hield had a team-high 22 but went more than 10 minutes in the second half without scoring before his layup gave the Sooners an 83-79 lead with 3:11 left.

Iowa State got 29 points on 13-of-18 shooting from Georges Niang, while Deonte Burton had 19 points on 8-of-11 shooting off the bench.

Michigan State's loss at Iowa earlier in the week sets it up so that Kansas and Oklahoma will likely be the two top-ranked teams in the country when they meet at Kansas on Monday.
