The Sterling Girls Softball Association (SGSA) was first formed in Sterling in 1974 and was commonly referred to as the Sterling Lassie League. In 2015, we opened our league to include Princeton as well.  The SGSA is dedicated to teaching the young women of Sterling and Princeton the fundamentals of softball, keeping in mind that the ideals of good sportsmanship, courage, honesty, loyalty, and respect for authority are of primary importance, and the winning of softball games is secondary to these principles.


We would like to take this opportunity to ask you for your support of the Sterling Girls Softball Association for the upcoming season.  Generous donations will allow us to purchase uniforms and equipment, maintain and update safe, attractive playing fields, and to offer an organized and enjoyable softball program to girls in Sterling and Princeton.


Please click here to find the Sponsorship Form.  Download a copy and circle your choice of participation for the upcoming season.  Completed forms should be returned to:


Sterling Girls Softball Association

P.O. Box 742

Sterling, MA 01564


This year, we ask that all sponsor forms be returned be returned no later than April 1st.  This will allow us the opportunity to have all uniforms delivered to the teams prior to opening day, eliminating the last minute rush.
