The Shelter Island boys varsity basketball team lost to the Stony Brook School in a Wednesday afternoon contest 71-47.
The Blue and Gray never led in the game, which was for the Suffolk County C-D championship.
Shelter Island claimed the County D championship with an historic win over Greenport earlier this week.
The Island boys move on to play at the Westchester County Center on March 4 against a team to be announced.
