Tu Holloway scored 14 of his 16 points from the free-throw line and Mark Lyons also had 16 points to help No. 8 Xavier hold off Butler 73-61 Wednesday night.
The Musketeers (7-0) kept their perfect record intact by scoring 10 straight points in the second half after leading by 18 in the first.
Butler (4-5) was led by Chase Stigall and Roosevelt Jones, who each had 10 points. But Jones needed to help to leave the floor in the second half after sustaining an apparent knee injury.
The Bulldogs have now lost back-to-back games for the first time since the 2006-07 season and haven't been under .500 this late in the season since 2004-05 when they finished 13-15.
