Memphis coach John Calipari, who led the Minutemen to the 1996 Final Four, was a surprise visitor for a ceremony naming "Jack Lehman Court" for the well-liked former coach and broadcaster.

Rashaun Freeman scored 15 of his 19 points and grabbed nine of his 12 rebounds after intermission for UMass (12-13, 7-7 Atlantic 10).

James Life led all scorers with 25 and held Dayton leading scorer Brian Roberts to nine points on 4-of-10 shooting.

Warren Williams was Dayton's only double-digit scorer. He shot 5-7 from the field, including three-for-three from three-point range. Dayton led 29-26 at the break.
