Elizabeth Williams scored 20 points to keep No. 4 Duke unbeaten with a 58-26 rout of Virginia Tech on Wednesday night.

Williams, who had her fourth 20-point game of the season, finished with eight rebounds. Chelsea Gray chipped in 12 points, while Haley Peters had five points to go with 10 rebounds.
Monet Tellier led the Hokies (7-10, 1-5) with 10 points. Ugu Ugoka had four points — on 2-for-13 shooting — and nine rebounds.
Duke shot 35.4 percent from the floor to 26.7 for Tech. The Blue Devils won the rebounding battle 49-34 and had 16 turnovers to the Hokies' 27.
Duke's next game is on Monday night at No. 3 Connecticut.
The Blue Devils have won 33 straight home games against ACC opposition. It was Duke's lowest scoring output of the season.
Virginia Tech, which lost by its largest margin of the season, was 1-for-10 from the free-throw line.
Duke led 29-12 at halftime behind 11 points from Williams. Gray had eight points and five steals over the period. The Blue Devils never trailed, with Williams' three-point play with 16:28 left in the first half making it 5-2 and starting a 7-0 run.
Tellier's 3-pointer at 10:02 cut the advantage to 16-12, but Duke ran off the last 13 points of the half.
Using a stifling full-court press the Blue Devils scored the first nine points of the second half, five from Williams, before a Hokie timeout at 17:51.
Duke scored 24 points before Tech freshman Alexis Lloyd, who didn't play in the first half, hit a short jumper to make it 40-14 with 17:19 left.
