DURHAM, N.C. (AP) - Nolan Smith scored 28 points and No. 5 Duke made its case to return to the top of the national rankings by routing Georgia Tech 79-57 on Sunday night.
Kyle Singler added 15 points and Ryan Kelly had 10 for the Blue Devils (25-2, 12-1 ACC). A technical foul on coach Mike Krzyzewski inspired the overwhelming run that carried Duke to its sixth straight win and 10th victory in a row in conference play.
Duke, the reigning national champion and preseason No. 1, slipped from that perch after a loss in mid-January but could return to the top spot Monday when the new poll is released. All four teams ahead of the Blue Devils - Kansas, Ohio State, Texas and Pitt - lost in the past week.
Iman Shumpert and Moe Miller had 13 points apiece, but they couldn't keep the Yellow Jackets (11-15, 3-9) from losing their sixth straight ACC game.

With losses in the past week by No. 1 Kansas, No. 3 Texas and No. 4 Pittsburgh, the Buckeyes entered the game in line to reclaim the No. 1 ranking they dropped after losing at Wisconsin on Feb. 12.

Talor Battle led Penn State (14-12, 7-8) with 23 points.
Leuer reached double figures for the 33rd consecutive game and Wisconsin avenged a 56-52 loss to Penn State three weeks ago when Battle scored 20 of his 22 points after halftime.

No. 23 Temple 66, Saint Joseph's 52
PHILADELPHIA (AP) - Lavoy Allen had 12 rebounds and became Temple's career leader in that category.
Allen scored 14 points for the Owls (21-5, 11-2 Atlantic 10) and passed John Baum on the school's career rebounding list. Baum, Temple's radio analyst, grabbed 1,042 rebounds in only three seasons. Allen, a 6-foot-9 senior forward, helped the Owls win their eighth straight game overall and ninth straight over their city-rival Hawks (7-19, 2-10).
Allen, who has 1,045 rebounds, scored eight points during Temple's 14-4 run late in the second half that broke the game open.
Allen sparked the Owls with a one-handed jam and a nifty spin move down the lane that gave them a 14-point lead. He was 7 of 10 from the field and grabbed 10 defensive rebounds.
