Duke led Virginia Tech for all of the second half, until the second to last play of the game.
Duke’s Marvin Bagley III contested Virginia Tech freshman Nickeil Alexander-Walker’s game-winning shot attempt, which went over the rim, only to watch it be tipped in by junior wing player Chris Clarke with just four seconds left.
Clarke’s tip-in gave the Hokies a 64-63 upset win over the fifth-ranked Blue Devils at Cassell Coliseum in Blacksburg, Va.
Duke had played its best basketball of the season recently. It had won five straight. And in four of those games, had given up less than 60 points.
