It doesn't happen very often but when it does, people notice. Two-time defending state field hockey champion Andover lost its first Merrimack Valley Conference game in five years Saturday, falling to Chelmsford, 3-1. As a result, Andover drops from No. 2 to No. 5, while the Lions leap-frog Andover to take the No. 4 spot.
Watertown remains No. 1 but Duxbury slides into No. 2 just ahead of Walpole. Those three schools are the only remaining unbeaten teams in EMass field hockey. Hingham is the lone newcomer to the Top 20, jumping in at No. 10.
