DURHAM, N.C. -- It came together at the right time for Duke's senior class.

Playing in the final home game of their careers, Seth Curry, Ryan Kelly and Mason Plumlee made another big impact at Cameron Indoor Stadium.

"I was trying to wipe that away and not think about it," Curry said of his home finale. "I got off to a bad start on both ends. I got some shots to do down and that's what you want on Senior Night."

The third-ranked Blue Devils rode their seniors to an 85-57 victory over Virginia Tech in an Atlantic Coast Conference game on Tuesday night.

Curry scored 20 points, Kelly had 18 points and Plumlee added 14 points for Duke, which went through its home schedule unscathed.

"The three seniors just asserted themselves in that second half," Duke coach Mike Krzyzewski said.

Duke (26-4, 13-4) clinched the ACC Tournament's No. 2 seed. The Blue Devils have a remote chance to finish as regular-season co-champions, but that would require winning Saturday night at North Carolina and having first-place Miami lose home games to Georgia Tech and Clemson.

Virginia Tech (13-17, 4-13) was denied in its quest for back-to-back victories for the first time since mid-January. The Hokies scored only 22 second-half points.

Virginia Tech guard Erick Green, the country's leading scorer at 25 points per game, racked up 25 points. He has reached the 20-point mark in 27 of 30 games.

The Hokies couldn't keep up with Duke even though signs of a third game in six nights showed on the Blue Devils.

"I think we were emotionally spent," Krzyzewski said. "With these last six days, it has been a heck of a thing. You could tell even the fans were emotionally spent from Saturday."

Duke made 7 of 12 3-point shots in the second half.

"They went inside and we had to collapse a little bit and they did a good job of kicking it out for some 3s," Virginia Tech coach James Johnson said.

Kelly was in his second game since nearly a two-month absence with a foot injury. He pulled down a game-high nine rebounds.

With Curry and Kelly dealing with injuries this season, there was a certain satisfaction.

"That's what makes us a little different," Kelly said. "The teams that have gone through a lot tend to make it to the end."

Duke scored on five of its first seven possessions of the second half -- with three 3-point baskets in that mix. That translated to a 13-4 run in slightly more than four minutes to build a double-digit lead for the first time in the game.

Still, the Hokies were within 53-47 with slightly more than 12 minutes to play. Duke scored 20 of the game's last 22 points.

"We were right there, but we didn't put a 40-minute game together," Green said.

Quinn Cook contributed 14 points for Duke.

Duke is 16-0 at home this season, finishing with its unblemished for the 16th season in Cameron Indoor Stadium. The Blue Devils have been undefeated at home in three seasons during a four-year span.

Kelly picked up where he left off in Saturday's 36-point outburst against Miami, scoring 14 first-half points to help the Blue Devils pull ahead of the Hokies.

But Duke's eight-point edge slipped to 38-35 by halftime, far smaller than less than two weeks earlier when the halftime gap was 20 points when the teams met.

Virginia Tech broke to an 8-1 lead, aided by two 3-point baskets by Jarell Eddie, who ended up with 13 points. Duke took its first lead since 1-0 on Curry's 3-pointer at the 6:38 mark, making it 25-24.

The Blue Devils led at the half for the first time in their last three games. Plumlee sat out most of the last 5:23 after picking up his second foul, though Virginia Tech starting forward Cadarian Raines played only four first-half minutes because of two early fouls.
