PARADISE ISLAND, Bahamas -- De'Andre Hunter was everywhere for fourth-ranked Virginia, finishing with 15 points, eight rebounds and a career-high nine assists.
"I thought De'Andre's completeness showed offensively and defensively," Virginia coach Tony Bennett said.
The 6-7 sophomore's size and athleticism caused problems for the Blue Raiders on the perimeter.
"We really spaced the floor (against) the 1-3-1 press," Hunter said. "And I was just looking for my shot when the guys kicked it to me in the corner."
Kyle Guy also scored 15 points for the Cavaliers (4-0), who led 9-0 and 30-9. But they needed Guy's 3-pointer to start a 9-0 run after the Blue Raiders had clawed to within 38-30 early in the second half.
Antonio Green scored 11 points to lead Middle Tennessee (3-2), which shot 39 percent.
The Cavaliers advanced to Thursday's semifinals to face Dayton, while the Blue Raiders will face Butler in the consolation bracket.
