Kansas 64, Ohio State 62: Thomas Robinson and Jeff Withey won the matchup of two of the nation's top frontcourt duos, and the Jayhawks overcame a double-digit deficit to beat the Buckeyes for the second time this season and advance to a championship matchup with Kentucky on Monday.

Robinson scored 19 points to lead four Jayhawks in double figures, and Withey had eight rebounds and seven blocks while pestering Buckeyes star Jared Sullinger all night.

Sullinger, who missed the Buckeyes' regular-season loss at Kansas with an injury, had 13 points and 11 rebounds, but his post partner Deshaun Thomas was held to nine points while spending much of the second half on the bench in foul trouble.

The Buckeyes led by 13 with 24 seconds left before half, but Kansas reeled off a quick four-point spurt culminating with Travis Releford's layup at the buzzer to get within 34-25 at halftime.

The Jayhawks kept the momentum rolling at the outset of the second half, opening with a 13-4 run while holding the Buckeyes without a field goal for the first 6:58 of the half.

Kansas quickly thawed out after a cold first half in which it shot 37 percent (11 of 30), including 1 for 6 from 3-point range. Elijah Johnson scored seven of his 13 points during that stretch, but he picked up his third foul shortly after and went to the bench. Johnson also had 10 rebounds.

Travis Releford hit two free throws with 2:48 left to give Kansas a 56-55 lead -- its first advantage since it was 2-0.

Senior William Buford scored 19 points to lead the Buckeyes in his final collegiate game.
