. BYSA is excited to offer an online registration and league management system for our members through SI Play. This system allows you to sign up for the season at your own convenience - 24 hours a day, 7 days a week. You can pay for registration fees online using either Visa or MasterCard, or you can pay by check or cash during in-person registration sessions. If this is your first time registering, you'll need to upload your child's birth certificate to verify their age. However, for subsequent seasons you won't need to do this again. The address you provide with your account will determine whether or not you are eligible to play within BYSA boundaries. Even if you are outside the boundaries, you can still register, but you will not be eligible for All Stars following the spring season.
