No. 2 Virginia 57, Georgia Tech 28: Malcolm Brogdon scored 13 points and the host Cavaliers leaned on their suffocating defense to remain undefeated.

Virginia (18-0, 6-0 ACC), the nation’s leader in scoring defense at 50.6 points per game coming in, held the Yellow Jackets (9-9, 0-6) to 24.5 percent shooting in continuing its best start since opening the 1980-81 campaign with 23 straight victories. Justin Anderson added seven points and four assists, and the Cavaliers got 25 points from their bench.

Marcus Georges-Hunt scored seven points to lead Georgia Tech, which finished with just two assists in dropping its first six conference games for the first time since 2008-09. It was an historically bad night for the Yellow Jackets, who scored their fewest points in a game since 1949 and did not make a 3-pointer for the first time since 2005.

Georgia Tech hit five of its first 11 shots, pulling within 13-10 on Georges-Hunt’s jumper with just under 11 minutes left in the first half. Anderson scored five points during a 10-0 surge to put the Cavaliers ahead 23-10, and Virginia held the Yellow Jackets to 2-of-14 shooting the rest of the period en route to a 28-16 advantage at intermission.

It was more of the same after halftime as the Cavaliers limited the Yellow Jackets to 12 points in the second half, Georgia Tech’s lowest-scoring half since joining the ACC in 1979. Brogdon’s jumper just over four minutes into the half ignited a 24-4 run that pushed the Virginia lead to 55-22 with 3:50 to play.
