We are and continue to be the premier baseball association not only on the Northwest Side of Chicago but in the entire country!

Raffle Tickets/End of Year Picnic

OPBA will once again provide raffle tickets to families in an effort to help offset the cost of the registration fees.  You sell the tickets, you keep the money, and turn the raffle tickets into the green bucket located on the front desk in the Oriole Park Field house.  All tickets need to be turned in by June 24, 2024.  Once the bucket is gone, it is gone!

We will unfortunately not be having our picnic this year (sad we have not had one since COVID, Chicago Park District requesting permits, and the lack of volunteers), so we will be drawing the raffles winners at the field house the week of July 8th.  A more specific time and date will follow regarding the drawing.

Welcome to the 2024 Oriole Park Baseball/Softball Season where we are home to the largest baseball/softball program in the city of Chicago and the largest single unit program in the country!  Just ask the 1500+ kids and their families that participate every season how they like us!!!
