The OK Classic Charity Softball Tournament is a one day, co-ed, 14-inch, charity softball tournament, and festival in benefit of the Warriors at Opportunity Knocks. The proceeds generated from this event will allow Opportunity Knocks to continue to administer and expand all of its amazing programs. None of this would be possible without the tireless efforts of volunteers just like you. We thank you for your continued, selfless support. Nearly 120 volunteer slots will need to be filled to staff this event! We need you!
