K.J. McDaniels scored 18 points and the Tigers rallied from a nine-point deficit in the second half, winning in overtime in the second round of the ACC tournament in Atlanta.

Trae Golden led No. 11 seed Georgia Tech (16-17) with 23 points, and Robert Carter Jr. added 13.

Golden converted a three-point play early in overtime and his jumper with 1:50 remaining put the Yellow Jackets ahead 62-60, but a free throw from Jaron Blossomgame and Harrison’s basket with 44.1 seconds left put the Tigers ahead 63-62. Harrison hit two free throws following a Georgia Tech offensive foul with 26.1 seconds to go and Clemson rebounded Golden’s miss on the other end and put the game away at the free throw line.
