MLBPA executive director Tony Clark is expected to step down, sources say, as the players union prepares for a critical labor dispute. Clark, who has led the union since 2013, is facing a federal investigation into the use of licensing money and equity. The investigation comes at a pivotal moment, with the current CBA set to expire and the owners threatening a lockout, potentially shutting down the sport for an extended period. Clark's resignation adds to the uncertainty, as the union seeks a new leader to navigate the upcoming negotiations. The owners' push for a salary cap, a move opposed by Clark and the union, could further complicate matters. This development highlights the challenges the MLBPA faces in maintaining player rights and competitive balance.
