CHARLOTTESVILLE, Va. (AP) -- -

Josh Gasser scored 11 points and No. 8 Wisconsin won a defensive struggle against Virginia 48-38 Wednesday night in the ACC/Big Ten Challenge, giving coach Bo Ryan his 300th victory with the Badgers.

The Badgers (9-0) extended their best start since 1993-94 by limiting Virginia to 23 percent shooting (11 for 47), including a stretch of nearly 22 minutes spanning halftime in which the Cavaliers managed just three field goals. The Badgers won going away despite shooting only 29 percent (15 for 52).

London Perrantes led Virginia (7-2) with eight points. The Cavaliers tried to make a run by speeding up the slow pace midway through the second half, but came up well short.

Joe Harris was called for a charge after a steal with Virginia trailing 43-36, and after Gasser made a free throw for Wisconsin, the Cavaliers missed three shots from within 3 feet on their next trip.

Virginia's 38 points were its fewest at John Paul Jones Arena.

“I thought we lost our composure a little bit," UVA coach Tony Bennett said. "We had some opportunities to finish, but we didn’t.  I think Wisconsin did to us, in a way, what we did to them last year. Last year we outlasted them a little bit. When it mattered, they were sounder, more poised, and made plays.”
