Severn made the biggest splash in a quiet week that led to little change in the poll.
In coming away with a 9-6 win over St. Mary's on Friday, the Admirals traded spots with the Saints -- moving up to No. 6 from No. 8 -- and, more importantly, claimed the sixth and final playoff spot in the upcoming Maryland Interscholastic Athletic Association A Conference playoffs.
Elsehwere, Gilman's thrilling 11-10 overtime win at Boys' Latin moves the Greyhounds to No. 3 and drops the Lakers to No. 4.
Tuesday's District V championship delivers an interesting match-up with No. 9 Glenelg visiting No. 10 South River.
Tuesday also marks the final day of the regular season in the A Conference. While the six playoff teams have been determined, some jockeying for position remains. No. 2 Loyola needs a home win against Mount St. Joseph to claim the second seed, which would give the Dons a bye in Friday's quarterfinal round along with top-seeded Calvert Hall.
