ANN ARBOR, Michigan (Ticker) -- For the second game in a row, Daniel Horton came up big for Michigan in the National Invitation Tournament.

Horton scored 12 points and stopped a late run with a contested floater in the lane as Michigan held off Oklahoma, 63-52, to advance to the quarterfinals of the NIT.

Horton, who struggled for much of his sophomore season, matched a season high with 20 points in a 65-64 first-round triumph over Missouri on Tuesday.

Freshman Dion Harris had 17 points and Chris Hunter added 10 for the Wolverines (20-11), who host Hawaii on Wednesday for a berth in the semifinals at New York's Madison Square Garden.

Michigan held a 49-40 lead after Horton converted both ends of a 1-and-1 opportunity with 6:28 remaining. But Oklahoma did not wilt, pulling within 49-47 on a 3-pointer by Lawrence McKenzie with 3:40 left.

Neither team scored until Horton swished a shot over several defenders in the paint with 2:19 remaining, which broke a Michigan field-goal drought of 5:49.

After a pair of free throws by Harris made it 53-47, Horton cleared space with a behind-the-back dribble and scored on a runner in the lane to open an eight-point cushion with 1:11 left. Oklahoma got no closer than five points thereafter.

Brandon Foust had 14 points and eight rebounds and McKenzie added 10 points for the Sooners (20-11), who shot just 36 percent (19-of-53). Oklahoma went just 9-of-13 from the line while Michigan sank 21-of-28.

Michigan held just a 40-38 edge when Foust picked up an offensive foul with 9:38 remaining. Sooners coach Kelvin Sampson became irate at the call and was whistled for a technical foul that seemed to spur the Wolverines, who promptly went on a 9-2 run.

Sooners guard DeAngelo Alexander dislocated his right shoulder late in the first half and sat on the bench after the break with his arm in a sling.
