First, lets tackle the pickup team situation, anyone can be added to any pickup team at anytime, since you all signed your 2022 waiver for play. DO NOT PANIC!!! All you need to do is log in to your player profile on USSSA and hit the deny button on the team request that is trying to add you and you will be removed from that team.
Second, a verbal agreement, email, or text to any coach or sponsor is NOT a bonding agreement. Literally means absolutely nada, zero, zilch. Do NOT fall for this tomfoolery.
Third, here is the most important thing you need to know and pay attention to is the following. THE ONLY THING THAT BINDS YOU TO A PARTICULAR TEAM IS THE FOLLOWING. You accepting a invite and agreeing to the USSSA waiver for the 2023 season (which are not out as of yet), for that particular team. You may gets request(s) from more than one team, so it is important to read your waiver thoroughly before clicking accept to assure you are accepting to the team you actually want to play for in 2023.
Personal contracts with manufacture's that you may have will supersede the above depending on the verbiage of said personal contracts.
