February 14th Update: Our Ladies division has limited spots. Masters, Men's, and Mixed divisions are at capacity, and we are accepting names for each division's waitlist. We're hoping to expand our Mixed division to 12 teams but in order to do so, we need more women to go on our waitlist. There's also a strong possibility of expanding the Masters division to 8 teams so make sure to add your name to the waitlist. 

Welcome to our 50th Season!!!!

Registration is now open for all players with fees set at $215/division. *We are holding off on accepting registrations for our Midseason Fun Tourney until we can secure a park permit. We'll provide an update if we are successful. If you're new to TSP, simply click on Login, and follow the prompt for creating a new account. Returning players, simply sign into your profile and complete all necessary steps, including payment to confirm your registration. 
Looking forward to seeing everyone on the diamonds for our Golden Year!
