STARKVILLE, Miss. (AP) — Top-ranked Kentucky fought off a slow start to cruise to a 74-56 victory over Mississippi State on Wednesday night to keep its undefeated season on track.

The Wildcats had to work a little for this one, leading just 41-37 with 15:10 remaining. But they responded with an avalanche of points down the stretch — punctuated by a thunderous dunk by Karl- Anthony Towns — to turn the contest into another convincing blowout.
