INDIANAPOLIS (AP) — Tyler Kolek had 21 points and 10 assists, and No. 6 Marquette clinched its first outright Big East championship by beating Butler 72-56 on Tuesday night.

The victory was the fifth in a row and 10th in 11 games for the surprising Golden Eagles (24-6, 16-3), picked ninth by the league’s coaches in the preseason poll.

This week, Marquette ascended to its highest ranking in the AP Top 25 since it was No. 1 in 1978.

Marquette, which had already secured a share of its first Big East title since 2013, had not won an outright regular-season crown since doing so in Conference USA in 2003.

Olivier-Maxence Prosper added 14 points and Oso Ighodaro had 12 for the Golden Eagles, who will be the top seed in the Big East Tournament at Madison Square Garden — an event Marquette has never won.

The Golden Eagles will open in the quarterfinals March 9 against the winner of a first-round game between Butler and St. John’s.

Marquette joined the Big East for the 2005-06 season, and that shared title with Georgetown and Louisville in 2013 was the only previous Big East title for the Golden Eagles.

This also marks the first regular-season conference championship for Shaka Smart in his 14 years as a Division I head coach. Smart is in his second season at Marquette after spending six each at VCU and Texas.

In the second half, the Golden Eagles shot 65% (15 of 23) from the floor and led by as many as 24 points.

Jayden Taylor scored 13 and Jalen Thomas had 10 for Butler (14-16, 6-13), which finished 4-6 in Big East home games.

Butler shot 0 of 10 while going scoreless for nearly nine minutes in falling behind 16-6. After the Bulldogs closed to 18-13, Marquette went on a 14-3 spurt to seize a 32-16 lead.

Butler was never closer than 11 points thereafter.

Marquette shot 72% (13 for 18) on 2-pointers in claiming a 36-22 halftime advantage. Kolek had 11 points at the break.

Butler center Manny Bates was back in the lineup after missing two games with a shoulder injury. Another Butler regular, wing Ali Ali, was sidelined by concussion protocol for the second time this season.
