The Wildcats (6-0) concluded a busy season-opening stretch of six games in 11 days with a complete effort on both ends. Besides shooting 57 percent from the field (30 of 53), Kentucky held the Mavericks (3-2) to 27 percent shooting.
Second-platoon guard Booker followed Sunday's 18-point effort by hitting 7 of 8 shots, including five 3-pointers. Towns added three blocks and four assists for Kentucky, which led 55-12 at halftime and rarely let UTA get within 40 points afterward in ending the Mavericks' two-game winning streak.
Dakari Johnson scored all 12 points on free throws, twin guards Aaron and Andrew Harrison each had 11 points and Trey Lyles 10 for the Wildcats.
