ROSEMONT, Ill. (AP) -- Darius Johnson-Odom scored 23 points and Jamil Wilson added 18 points and nine rebounds to lead Marquette.
Trailing 41-29, Johnson-Odom scored nine points during an 11-2 run by the Golden Eagles (20-5, 9-3 Big East) to close the first half. He opened the second half by hitting a 3 that tied the game at 43, and Jae Crowder gave the Golden Eagles their first lead of the game with a free throw. Vander Blue hit a jumper to cap off a 16-3 run to open the second half and give Marquette a 56-46 lead.
Marquette rebounded from a blowout loss to Notre Dame on Saturday that ended a seven-game winning streak.
Cleveland Melvin scored 22 points and Jamee Crockett added 17 for DePaul (11-12, 2-9), which has lost 36 consecutive games against ranked opponents since beating No. 17 Villanova 84-76 on Jan. 3, 2008.

NO. 24 LOUISVILLE 80, CONNECTICUT 59
LOUISVILLE, Ky. (AP) -- Gorgui Dieng returned from a sprained right ankle to score 15 points and freshman Chane Behanan added 12 rebounds as Louisville won its fifth straight.
Chris Smith scored 16 points for the Cardinals (19-5, 7-4 Big East), while Kyle Kuric added 10 and Peyton Siva had nine assists.
Dieng was questionable after Saturday's injury in a win over Rutgers, but he clogged up the lane and kept Connecticut freshman Andre Drummond in check.
Freshman Ryan Boatright led the Huskies (15-8, 5-6) with 18 points. Drummond went scoreless, missing all six shots, and Jeremy Lamb finished with seven points, well short of his average of 17.6.
Connecticut coach Jim Calhoun missed his second game on an indefinite medical leave of absence after he was diagnosed with spinal stenosis.
Dieng was a key contributor in the Cardinals' decisive 21-4 run that gave them a 65-36 lead with 6:18 left.
