INDIANAPOLIS (AP) _ Michael Redd scored 27 points and Ohio State got 13 of its final 17 points from the free-throw line in a 72-58 victory over Murray State in the first round of the NCAA South Regional on Thursday night.

The fourth-seeded Buckeyes (24-8) took a 32-21 lead at the break and quickly built their lead to 17 points in the first minute of the second half. But the 13th-seeded Racers (27-6) used a full-court press, closed within 10 points midway through the period and kept the pressure on Ohio State the rest of the game.

After a 3-pointer by Slobodan Savovic, a rebound basket by Redd and two free throws by Jason Singleton gave Ohio State a 50-33 lead with 12 minutes left, Murray State fouled the Buckeyes on almost every possession the rest of the way.

The only Ohio State baskets over the final six minutes were on fast-break dunks by Singleton and Redd. Redd and Brian Brown, who made his first start of the season, each had four free throws during the Buckeyes' late parade to the foul line.

Murray State, which shot only 33 percent from the field in the first half, hit just 5 of its first 21 shots in the second period and finished the game at 27 percent. The Racers managed to stay within striking distance, however, because of seven missed free throws by Ohio State during the late streak. Two straight 3-pointers by Marlon Towns and four free throws by Aubrey Reese helped Murray State cut the lead to nine points.

One free throw by Scoonie Penn, two by Brown and a dunk by Redd after a steal by Singleton ended the game.

Singleton added 10 points for Ohio State. Reese led Murray with 26 points, while no one else scored more than eight.
