Tuesday’s winner meets No. 7 seed Stanford on Wednesday night.”Let’s go play well,” Virginia Tech coach Mike Young said. “Won at Cal earlier in the year.”No. 15 seed Cal (13-18) has lost seven of its last eight games. The Golden Bears nabbed the last berth into the ACC tournament in their first season in the conference.The Golden Bears were on the wrong end of the historic 112-110 four-overtime matchup with Notre Dame on Saturday. Jeremiah Wilkinson’s 36 points led Cal in that matchup, and he was one of three players on the team to log at least 50 minutes of playing time.Wilkinson will have another chance to show what he can do in the tournament. The freshman has averaged 20.4 points since joining the starting lineup 13 games ago.”He’s an unbelievable point guard,” Cal coach Mark Madsen said. “He’s an explosive scorer, but also does a really good job of looking for his teammates. He’s growing into one of the top point guards in the country.”
