Dayton (20-6, 10-4 Atlantic 10) had its three-game winning streak snapped and falls a game back of conference leaders Rhode Island (19-6, 11-3) and No. 25 Virginia Commonwealth (21-6, 11-3).
Mason had four steals and eight rebounds. Derrick Colter scored 25 points, Dominique McKoy chipped in 11 with a career-best five assists, and Jeremiah Jones added 10 points for Duquesne (9-16, 4-10).
