Big Monday among the top boys volleyball teams in the Central Region produced a new No.1 team in the RVC/Times-Dispatch Top 10. Cosby, which is unbeaten in the Dominion District and has a seven-match winning streak, ascended to No.1 after beating then top-ranked Thomas Dale in four games. Atlee beat Clover Hill in four games, and Deep Run defeated James River in four in Monday’s other matches involving the former top six teams.
