LAWRENCE, Kan. (AP) - Cole Aldrich had a double-double and blocked six shots, and No. 1 Kansas overcame a monumental lack of focus in the first half to wear down Belmont 81-51 on Tuesday night.

Kansas (12-0) was rusty early coming off a long break, even playing with just four players for a stretch of about 15 seconds in the first half. The Jayhawks pulled it together and played a superb second half at both ends, pulling away for their 50th straight home victory.

Aldrich had 11 points and 14 rebounds, and Marcus Morris added 14 points.

Belmont (7-5) was doomed by poor shooting and a shaky start to both halves in its first trip to Allen Fieldhouse.

The Bruins scrapped back after falling behind 11-0 to open the game, but they didn't have an answer when Kansas did the same thing to start the second.
