MILWAUKEE (AP) -- Trevon Bluiett had 18 points and No. 7 Xavier rode a 21-0 first-half run to seize control on the way to a 74-66 victory over Marquette on Saturday.
James Farr had 16 points and a career-high 19 rebounds and Edmond Sumner, returning from a concussion, added 15 points for Xavier (16-1, 4-1 Big East).
Freshman Henry Ellenson led Marquette with 20 points while Luke Fischer added 11.
Xavier led by as many as 16 points in the second half but went cold for a stretch, missing 11 of 13 shots at one point.
The cold-shooting Golden Eagles shot a season-low 34.3 percent.
Marquette (12-6, 2-4) got off to strong start, with Fischer scoring the team's first six points. The Golden Eagles built an early 15-6 lead, with Fischer and Ellenson accounting for a combined 13 points.
Marquette then went ice cold against Xavier's stifling 1-3-1 zone, going more than 8 minutes without scoring. A 21-0 run over that stretch gave the Musketeers a 32-18 lead.
Xavier led 38-28 at halftime. Ellenson had 11 first-half points for Marquette, which shot 31 percent, including 2 of 12 from 3-point range.
Xavier shot 47 percent in the first half.
The teams will meet in Cincinnati on Feb. 6.
Sumner, a redshirt freshman point guard, returned after missing three games with a concussion. Sumner was injured in a scary spill in the opening minutes of a loss at Villanova on Dec. 31. He was taken off the court on a stretcher and transported to a hospital. . Bluiett has scored in double figures in 16 of Xavier's 17 games.
