Catholic Memorial dropped a spot to No. 4 after losing on Tuesday to BC High (now No. 6). BC High then lost to St. John's Prep on Friday, proving just how tight things are in the Catholic Conference.
The Boston City League had plenty of movement as well, with Madison Park continuing its rise up the rankings. The Cardinals, who defeated a banged up No. 17 Charlestown team, 81-69, on Thursday, now sit at No. 7. East Boston's loss to No. 8 North Andover, caused them to slide from No. 4 last week to No. 12.
No. 18 Mansfield saw its 27-game winning streak in the Hockomock League come to an end at the hands of Franklin on Friday.
Last week's notebook team, Boston Latin, faced its first real test in Catholic Memorial on Saturday and lost by 20. However they'll have another chance to show they belong when they travel to No. 9 Acton-Boxboro this Friday.
After winning their last 10 games the Rockets of Reading earned a promotion to No. 19 and a spot in this week's notebook.
