It was Dodson's first start since the season opener. He quickly extended UK's streak of 732 consecutive games with a three-pointer with a triple at the 18:19 mark.
Eric Bledsoe was UK's first substitute. Bledsoe had started every game except the Hartford contest, which he missed because of injury.
DeMarcus Cousins got off to a quick start with 13 points in the first nine minutes. Included were four baskets in which Cousins got fouled, three of which he turned into three-point plays. It is the third straight game, and the sixth this season, in which Cousins has reached double-figure scoring in the first half.
Kentucky took the lead at 4-3 and extended it to as many as 19 points at 46-27.
With foul trouble sidelining Cousins, Patterson, Miller, Wall and Orton, UK hung on to a 15-point lead at halftime, 49-34.
