HARRIS (AP Photo/Steve Helber)Big wins, followed by big losses. N.C. State snaps a 13 game losing streak against rival North Carolina and then loses to Virginia on the road...C.J. Leslie was sick and Lorenzo Brown sprained his ankle to add to the Wolfpack’s woes...VIRGINIA 58, #19 N.C. STATE 55 - The little things that Virginia coach Tony Bennett preaches about doing are starting to add up to regular victories, and the fact that his freshman-heavy team is starting to find its comfort zone is helping a great deal, too.Joe Harris scored 22 points, seven during a game-ending 13-6 run, and Virginia's nationally ranked defense slowed No. 19 North Carolina State's ACC-best offense just enough for a victory Tuesday night, the Cavaliers' fourth straight victory.One game after freshman Justin Anderson led the way for Virginia, fellow freshman Mike Tobey had a huge hand in the victory with 13 points and, more importantly against the long, athletic Wolfpack, seven rebounds and two blocked shots.Akil Mitchell added 14 points and 12 rebounds for Virginia (15-5, 5-2 Atlantic Coast Conference), including an 18-foot jumper that put them ahead to stay with 3:53 remaining, before the nation's No. 2 scoring defense (51.1) closed it out.Recap.
