Jon Diebler added 12 points for the Buckeyes (18-6, 8-3), who have won four in a row overall and seven of eight.

Eric May scored 16 points, Aaron Fuller and Cully Payne 11 each, and Matt Gatens 10 for the Hawkeyes (8-16, 2-9), who have lost four in a row and won just once away from home.

It was Ohio State's second win over the Hawkeyes in 12 days. The Buckeyes finished strong in Iowa City to win 65-57 on Jan. 27. The Buckeyes moved to 15-0 at home this season, where they are shooting 54 percent from the field and 42 percent on 3-pointers.

But this was not a typical hot-shooting home game. Ohio State made just 22 of 49 shots from the field for 45 percent, and was only 2 of 13 behind the arc.

Ahead by five at the half, Ohio State pulled away when Iowa hit 1 of its first 9 shots.

Turner, who scored 20 points in the last 20 minutes, got things going on what would become an 11-2 run, including Kyle Madsen's bucket to close the half. Turner hit a 15-foot jumper on the first possession and later hit another shot off an inbounds pass. William Buford hit two foul shots and had two assists, including on Diebler's 3 from in front of the Ohio State bench that made it 41-29.

The Hawkeyes were able to get as close as 51-43, but Turner responded with a baseline jumper and a slashing drive through the lane. Iowa was down 55-46 but missed three consecutive 3-point shots on the same possession, thanks to two offensive rebounds. Turner finally ended the lengthy trip down the floor with a rebound, then dribbled the length of the floor, faked May on a drive and coasted in for an easy finger-roll.

There was another point in the game where, after some physical defense from Iowa's John Lickliter, son of head coach Todd Lickliter, Turner dribbled to the top of the key and held the ball behind the Iowa defender's head. The crowd laughed.

The Buckeyes were without center Dallas Lauderdale for large portions of the game. He was tagged with his third and fourth fouls at the outset of the second half and sat out much of the remainder of the game.

Iowa hit 7 of its last 11 shots from the field to keep up with the Buckeyes at the half, 32-27. May hit both of his 3s as the Hawkeyes went 4 of 5 behind the arc.

Meanwhile, the Buckeyes were cold from the perimeter. Turner had 12 points, but most of them came off drives and layups in traffic. Ohio State hit just 1 of 7 3-pointers, with Buford and David Lighty each going 0 for 2.

The Buckeyes never trailed, but couldn't put any distance between themselves and the Hawkeyes, either. They put together a 19-12 lead on Turner's steal and breakaway dunk, but Iowa answered by scoring on six of its next eight possessions.

It was ''Military Appreciation Day,'' and the game ball was delivered by a former Ohio State ROTC member who rappelled down from the ceiling.
