Duke center Elizabeth Williams (1) loses control of the ball as Georgia Tech guard Metra Walthour defends during the first half of an NCCA basketball game on Wednesday, Jan. 18, 2012, in Duluth, Ga.

DULUTH, Ga. — Elizabeth Williams had 20 points and 11 rebounds, Richa Jackson added 17 points and No. 5 Duke won its ninth straight game with a 79-62 victory over Georgia Tech on Wednesday night.

The Blue Devils (15-2, 5-0 Atlantic Coast Conference) have beaten Georgia Tech 34 straight times and haven't lost to the Yellow Jackets since Feb. 27, 1994.

Sasha Goodlett finished with 25 points for Georgia Tech (13-6, 3-3). The Yellow Jackets, who had a two-game winning streak snapped, have lost three of five with all three defeats coming to ranked ACC rivals Maryland, Miami and Duke.

Georgia Tech had a chance to cut the lead to three, but Tyuanna Marshall's fast-break layup attempt rolled off the rim with 16:09 remaining.

Less than 6 minutes later, Duke led by 16 on Shay Selby's three-point play.
