ORLANDO – Having shaken off the rust and calmed the nerves from opening day of the 46^th annual AAU Volleyball Junior National Championships, the championship-caliber teams in the 15 and 17 divisions began to show a little separation from the rest on Saturday. Players in every possible position on the floor turned in strong performances on Day 2 of the four-day tournament, setting their teams up for a big push on the final two days. Teams will compete in the third round of pool play and crossover and challenge round matches on Sunday.
