GREENSBORO, N.C. — Dez Wells gave the floor a hard slap, and No. 2 Duke certainly felt it.

It knocked the Blue Devils out of the Atlantic Coast Conference tournament early — and maybe off the No. 1-seed line for the NCAA tournament, too.

Wells scored a career-high 30 points and Maryland upset Duke 83-74 on Friday night in the ACC tournament quarterfinals.

Wells was 9 of 13 from the field and 10 of 10 from the free throw line to lead the seventh-seeded Terrapins (22-11), who delivered the first big shocker of the week in Greensboro and advanced to the semifinals for the first time since 2009.

“You have to be good and be lucky to beat a great team. We’re a little bit of both,” Maryland coach Mark Turgeon said. “Watching them play tonight, I think they fully expected to win that game and that’s a good feeling when you have such a young basketball team to play on such a big stage in such a big game and to play with the poise that they played tonight.”

They never trailed, held the league’s best three-point-shooting team to 4 of 25 from beyond the arc and bolstered their NCAA tournament credentials by beating Duke for the second straight time.

“One of the things during this time of the year … is that if you lose, it’s final,” coach Mike Krzyzewski said. “Our team did not feel that. And now we have to understand that that’s the way it is. I mean, if you don’t do it, it’s done.”

Mason Plumlee had 19 points to lead the second-seeded Blue Devils (27-5).
