Kentucky trailed 11-8 when Duke scored the game’s next nine points in less than two minutes. Reddish hit another 3-pointer, Jones and Bolden hit layups and Barrett ended a fast break with a slam dunk to give Duke a 20-8 lead.
When Barrett scored inside at 11:47, Duke had made 11 of its first 19 shots and six Blue Devils had scored to build a 27-10 lead.
The Blue Devils found themselves in deep foul trouble as six players, including Reddish, Williamson and Bolden, picked up two fouls each in the first half. That allowed Kentucky to climb back as close as 12 points.
But Duke closed the half getting easy baskets from Barrett, off a pass from Jones, and Bolden, off a pass from Barrett, to lead 59-42 at intermission.
A Williamson layup and Reddish three-pointer in the first minute of the second half pushed Duke’s lead to 64-42 and caused Kentucky coach John Calipari to call a timeout.
A Reddish steal and slam after play resumed boosted Duke’s lead to 66-42.
