RALEIGH, N.C. — Kerry Blackshear had 13 points and 13 rebounds Saturday to help No. 12 Virginia Tech beat No. 23 North Carolina State 47-24 in the Wolfpack’s lowest-scoring output of the shot-clock era.

Nickeil Alexander-Walker added 11 points for the Hokies (18-3, 7-2 ACC), who led the entire way despite playing without point guard Justin Robinson. Virginia Tech didn’t put up huge numbers, shooting just 36 percent and making 7 of 21 3-pointers.

Then again, Virginia Tech didn’t need much production against the cold-cold-cold-shooting Wolfpack (16-6, 4-5).

N.C. State made just 9 of 54 shots for the game, a conversion rate of 16.7 percent that included a 2-for-28 showing from 3-point range. It was N.C. State’s lowest scoring output in any game since managing 12 points in a win against Duke in the 1968 ACC Tournament, nearly two decades before the implementation of the shot clock.
