It was another hectic week for the Massachusetts POWERADE state rankings, with major shake-ups throughout the top 10. Last week's No. 2 team, Northfield-Mt. Hermon (which actually held the top spot earlier in the season), lost to Brewster Academy, dropping the Hoggers down to No. 4 this week.
Former No. 3 Catholic Memorial also suffered a setback, dropping a heartbreaking game to Brockton at the buzzer. Brockton moves from No. 6 to No. 2 with the win, while CM falls to No. 6 this week.
Western Mass power Springfield Central also reaches its highest point so far this season, checking in at No. 3 after downing Springfield Cathedral.
