Back and forth went Marquette and Butler, trading makes and misses in a high intensity rematch.
In the end, Vander Blue and the Golden Eagles (25-8) advanced as the Bulldogs (28-9) couldn't muster any more of their March magic.
Blue scored 19 second-half points to rally third-seeded Marquette out of another hole, and the Golden Eagles survived 74-72 on Saturday in Lexington, Ky., to reach the Round of 16 in the NCAA tournament.
"I know everybody in our team, we weren't ready to go home," said Blue, who made a last-second layup to win Marquette's first game of this tournament. "We had two close games -- we had a lot of those this year. What we went through earlier this year prepared us for this weekend."
Marquette will meet the winner of Sunday's game between Illinois and Miami (Fla.) on Thursday in the East Regional semifinals in Washington, D.C.
