No. 17 Butler 79, Dayton 73: Roosevelt Jones had 16 points and seven rebounds and the visiting Bulldogs extended their winning streak to 11 after leading scorer Rotnei Clarke left the game on a stretcher in the first half.

Dayton trailed 65-60 with 5:10 left after Stanford scored 10 straight points, but Smith answered with a 3-pointer on Butler’s next possession to quiet the raucous near-sellout crowd at UD Arena. The Flyers were unable to get closer than four points in the final minutes.
