COLUMBIA, Mo. (AP) _ Reserve Kirk Haston scored all 17 of his points in the second half as No. 15 Indiana, once down 16 points, rallied to beat Missouri 73-68 on Tuesday night.

Haston played only four minutes in the first half and missed his only shot, but was on the floor for the final 20 minutes. He made a running hook that tied it 66-66 with 1:33 to go and then passed to Dane Fife for the go-ahead layup with 43 seconds left.

Indiana (5-0) won despite an off game from A.J. Guyton, who had 16 points on 4-for-11 shooting and six turnovers. Guyton had been averaging 21.3 points.

Fife and Michael Lewis each had 13 points for the Hoosiers, who played at Missouri for the first time since 1969. Former Missouri coach Norm Stewart, who never faced Indiana coach Bobby Knight during the regular season, made his first visit back to the Hearnes Center since retiring last April.

Keyon Dooling bounced back from two mediocre games with 21 points for Missouri (5-2), hitting seven of 14 shots and making four 3-pointers. He was 3-for-22 in the previous two games.

Kareem Rush added 16 points and Clarence Gilbert 12 for the Tigers, who shot 50 percent in the first half but only 31.4 percent the rest of the way.

Indiana, down 34-18 in the first half, tied it for the first time on two free throws by Guyton with 2:18 left.

The Hoosiers closed the first half on a 10-3 run and came back after halftime with another 10-3 run that cut the deficit to 40-38.

Missouri responded with 10 of the next 12 points, but couldn't hold off Indiana's last charge, which coincided with a mini-tantrum by Knight during a timeout with 3:48 to go and the Hoosiers trailing 64-59.

Knight started to diagram a play and then slammed his clipboard to the floor.

Dooling had 12 points in the first eight minutes of the first half before sitting down with two fouls.
