Alabama pulled back on its full-court defense in the second half after the Wildcats hit 14 of 29 shots (48.3 percent).
"They just said, 'Don't even press. We're just going to lock them in on the half-court and be physical,'" Calipari said. "They ran and got good shots and got second shots and we didn't."
The Tide won despite getting outrebounded 44-32, shooting 36.8 percent (21 of 57) and making only two 3-pointers.
Ryan Harrow ended the shooting drought with an open layup set up by Noel's block on a drive by Lacey. Harrow, who had scored in double digits for eight straight games, was 3-for-12 shooting and had six points.
The Wildcats didn't hit a 3-pointer for nearly 13 minutes to open the game, then made three quick ones. Mays hit two and Wiltjer followed up with another 3-pointer during a 17-6 run that stretched Kentucky's lead to 11 points late in the first half.
Randolph's shot in the final seconds didn't go in and the Wildcats took a 33-24 lead into halftime.
