BLOOMINGTON, Ind. — Eric Gordon scored 29 points and D.J. White added 18 to help Indiana rally past Georgia Tech 83-79 on Tuesday night.

Jamarcus Ellis scored 12 of his 15 points in the second half for the 15th-ranked Hoosiers in their 21st straight regular-season win at Assembly Hall. It also was the Big Ten’s first victory in this year’s Big Ten/ACC Challenge.

Georgia Tech (3-3) was led by Lewis Clinch with 18 points. Anthony Morrow and Gani Lawal each added 17.

Indiana (5-1) started both halves sluggishly, committing five turnovers in the first four minutes of the game and allowing Georgia Tech to open the second half on a 9-0 run, which erased the Hoosiers’ 38-34 halftime lead.

But Indiana used some nifty drives by Gordon and Ellis to retake the lead, and the strategy eventually opened things up down low for White and on the perimeter for the outside shooters. The result: Lance Stemler’s 3-pointer with 7:20 to go not only gave Indiana a 60-58 lead, but also sparked an 11-2 run that made it 68-60.

Georgia Tech got as close as 68-64 and was within five with less than a minute left, but the Hoosiers’ late free-throw shooting sealed the victory.

Indiana played without freshman guard Jordan Crawford, suspended for three games minutes before the opening tip for violating team rules.

The announcement was made by coach Kelvin Sampson. Crawford was averaging 12.6 points.
