The 6-foot-11, 245-pound freshman turned in his 13th double-double by hitting 8 of 14 shots and making both of his 3-point attempts. He made 14 of 16 free throws and blocked six shots.
His tip-in off his own miss gave the Golden Eagles (15-7, 4-5 Big East) a 72-69 lead with 28 seconds left. Marquette added four free throws while Butler (14-7, 3-6) missed a pair of 3-pointers.
Marquette led the final nine minutes but not by more than six.
