Allen scores 28, No. 5 Duke routs Louisville 82-56. DURHAM, N.C. (AP) — Grayson Allen scored 28 points and No. 5 Duke routed Louisville 82-56 on Wednesday night. Freshman big man Wendell Carter Jr. finished with 18 points and a season-high five assists, and Gary Trent Jr. had 11 points to help the Blue Devils (23-5, 11-4 Atlantic Coast Conference) win their fourth straight game — all coming with star freshman Marvin Bagley III out with a sprained knee. Ray Spalding scored 17 points, and V.J. King and Deng Adel had 10 apiece for Louisville (18-10, 8-7), playing for the first time since an NCAA panel upheld sanctions against the program in the wake of its embarrassing sex scandal — which cost the school about $600,000 in tournament revenue, 123 victories and its most recent national championship. The Cardinals were taken out of this one early by a Duke team that shot 48 percent, hit nine 3-pointers — with Allen responsible for six of those — and pushed its lead into the 20s with a 26-6 run midway through the first half fueled by a pair of Allen 3s.
