GREENSBORO, N.C. (AP) -- Iman Shumpert scored 14 points and made the key defensive play that lifted Georgia Tech past No. 19 Maryland 69-64 on Friday night in the Atlantic Coast Conference quarterfinals.

Maurice Miller added 13 points for the seventh-seeded Yellow Jackets (21-11). They blew most of a 19-point lead and had 25 turnovers, but held on to advance to the semifinals for the first time since 2005.

Greivis Vasquez had 17 points on 6 of 21 shooting for the Terrapins (23-8). They had the ball and were within one possession of the lead six times in the final 4:30 and didn't score on any of those possessions.

The last chance came when Maryland trailed 67-64 and Vasquez pulled up for a long 3-pointer with about 6 seconds left. Shumpert knocked the ball from his hands, took off downcourt and was fouled. He and Derrick Favors hit one free throw apiece in the final 3.7 seconds to seal the Yellow Jackets' first victory in the series since 2004.
