When Virginia lost at home to Louisville two weeks ago, it began what is now a four-game losing streak for the Cavaliers.They’ll aim to snap the skid on Saturday afternoon when they travel to face a Cardinals team now streaking in the opposite direction.The Cavaliers (8-9, 1-5 Atlantic Coast Conference) almost ended their losing streak on Wednesday, but SMU’s Boopie Miller’s desperation 3-point heave went in just before the buzzer to stun Virginia 54-52.Despite the loss, interim coach Ron Sanchez still was able to take some positives from the game, telling reporters afterward his team battled despite a poor shooting night from their two leading scorers, Isaac McKneely (six points, 1-for-9 shooting) and Elijah Saunders (eight points, 1-for-5 on 2-point attempts)”It’s definitely a step in the right direction with this group,” Sanchez said Wednesday night.Blake Buchanan led Virginia with 11 points and a career-best 15 rebounds. Sanchez said that if the sophomore forward can duplicate that kind of performance with McKneely (11.9 points per game) and Saunders (11.6 ppg) playing to their standards, they would be able to compete on the road.Virginia is 0-4 in road games this season, with all of its losses by 12 or more points.
