What happens in the Assabet Valley Girls locker room stays in the Assabet Valley locker room. And whatever that is, it works. Assabet Valley's 12U girls jumped out to a 4-0 lead in the first period and made it stand up for a 5-2 victory over the Cal Selects in Sunday's championship game of USA Hockey's Girls Nationals. The win gave Assabet its fourth consecutive Nationals title for that age group.
