MLBPA Tables First CBA Proposals as Lockout Clock Ticks
The players' union has submitted its opening policy proposals for the next collective bargaining agreement, signaling the start of a potentially contentious negotiation cycle.

Formal CBA negotiations between MLB and the MLBPA began May 12 with opening presentations from both sides. The union released its first substantive proposals on May 27, favoring modifications to the existing system over a full overhaul. Key proposals include a competitive-integrity tax targeting teams that spend below $150 million and an increase to the league minimum salary. The article frames these developments as the early stages of a march toward a potential work stoppage.
