CHAPEL HILL (AP) -- Deron Washington blocked Ty Lawson's shot in the final seconds of overtime to preserve Virginia Tech's 81-to-80 upset of Number Four North Carolina tonight.
Zabian Dowdell scored a career-high 33 points to help the Hokies to an improbable season sweep of the Tar Heels.
Markus Sailes gave the Tar Heels one last chance when he missed two free throws with seven-point-one seconds left. Lawson rushed down the court and took a quick shot which was tied up by Dowdell. Lawson got the rebound and shot again from the lane, but Washington swatted it away.
Wayne Ellington grabbed the ball and the buzzer sounded just before he released and hit a 3-pointer.
Virginia Tech won its second straight against the Tar Heels, after beating them 94-to-88 last month.
