The road to the Interscholastic Athletic Association of Maryland (IAAM) lacrosse championship got underway Thursday afternoon with opening round play in the A Conference tournament. The IAAM is Maryland's top girls private school lacrosse league and perhaps the best conference in the nation.

Top-seed McDonogh School, the top-ranked team in High School on SI’s DMV Top 25 rankings, defeated No. 8 seed and 21st-ranked Bryn Mawr School, 16-9. The Eagles, seeking their second title in three seasons, will play No. 6 Maryvale Prep in the semifinals Tuesday afternoon.

Maryvale, the tourney No. 4 seed, eliminated No. 5 seed and 15th-ranked Notre Dame Prep, 18-9. St. Paul’s School took the first step in another title pursuit Thursday. 

The second-ranked Gators, the tourney No. 3 seed, held off No. 6 seed and 18th-ranked John Carroll School, 9-4. St. Paul’s, aiming for a second straight crown and fourth in five seasons, will match up with Archbishop Spalding in Tuesday’s A final four. 

No. 5 Spalding (No. 2 seed in tourney) edged No. 7 seed and 11th-ranked St. Mary’s, 9-8. The Cavaliers, who dropped four of its first five matches in April, have won six straight. Spalding, seeking its first A Conference title game berth, defeated St. Paul’s in overtime, 9-8, in March. 

McDonogh defeated Maryvale, 11-10, a couple of weeks ago. Tuesday’s semifinal survivors will advance to the title game at USA Lacrosse’s Tierney Field May 9.

The IAAM B and C playoffs start Friday with quarterfinal contests. No. 24 Mercy is the No. 1 seed in the B and Annapolis Area Christian School is the top-seed in C.
