GREENSBORO, N.C. — With the game on the line, Maryland put the ball in the hands of the ACC's player of the year.
Somehow — and against instructions — Iman Shumpert took it away from him.
Shumpert scored 14 and made the key defensive play on Greivis Vasquez that lifted Georgia Tech past No. 19 Maryland 69-64 on Friday night in the quarterfinals.
"We actually wanted to foul there," coach Paul Hewitt said. "He just stepped up and made a big-time defensive play."
Maurice Miller added a season-high 13 points for the seventh-seeded Yellow Jackets (21-11), who blew most of a 19-point lead and had 25 turnovers.
Vasquez had 17 points on 6-of-21 shooting for the second-seeded Terrapins (23-8), who trailed 67-64 with about six seconds left. Vasquez pulled up for a long 3-pointer, but Shumpert stripped the ball from him.
"I figured he was going to try to get a foul on me," Shumpert said. "I just kept replaying in my head that last time he made a big shot against us. I figured if he showed the ball I would deflect it. What I tried to do is deflect it up instead of smacking it down."
Shumpert took off and was fouled, and he and Derrick Favors each hit one free throw in the final 3.7 seconds to seal the win for the Yellow Jackets, who face No. 11 seed N.C. State.
No. 4 Duke 57, Virginia 46: Kyle Singler scored 18, Nolan Smith 15 and Jon Scheyer, the third member of Duke's "Big Three," seven of his 15 in an 11-0 run. Scheyer missed 12 of his first 14 shots before getting hot.
"He's that guy that you want on your baseball team who goes 0-for-4; bottom of the eighth, he gets a double, knocks in the winning run," Duke coach Mike Krzyzewski said. "He goes onto the next play really well."
Up 48-44 with about six minutes left, Smith started the run by putting back Singler's miss. Scheyer banked in a jumper. Singler made a putback, and Scheyer took over from there, knocking down a hanging jumper and converting a three-point play that put Duke (27-5) up 57-44 with 2:32 left.
"I wasn't in a very good rhythm in the beginning of the game," Scheyer said. "And I just started playing head games a little bit. Finally, I just started attacking and not (worrying) about if I was missing."
The Cavaliers (15-16) failed to reach the semifinals for the first time since 1995.
"We looked like we ran out of a little gas maybe the last five minutes," coach Tony Bennett said. "I think we had Duke nervous for a little while. But they showed why they're a heck of a team."
Miami 70, Va. Tech 65: Durand Scott scored 11 of his 17 over the final six minutes as the Hurricanes, who finished last in the regular season, pulled off their second upset in two days. Miami (20-12) had lost 11 of 14 entering the tournament.
"We regrouped and told each other, 'The season's over with. Come here and start over and just have fun,' " said Reggie Johnson, who had 12 rebounds. "And we're having fun right now."
The ACC's top scorer, Malcolm Delaney, scored just seven on 3-of-15 shooting for the Hokies (23-8). Tech must wait to see if it makes the NCAA Tournament.
