What happened: Major League Baseball has formally proposed a new economic structure featuring a hard salary cap of $245.3 million and a mandatory salary floor of $171.2 million. The MLB CBA proposals, detailed by ESPN, aim to implement a 50/50 revenue split between owners and players as the current labor agreement nears its December expiration.

Why it matters: The move represents a radical shift toward models used in the NBA and NFL, potentially forcing 12 teams to increase spending while requiring high-budget clubs to cut payroll. However, the MLBPA remains staunchly opposed to any hard cap, raising concerns of a potential lockout if an agreement isn't reached by the December 1 deadline.

What to watch: Negotiations are expected to intensify through the summer as the union prepares a counter-proposal. Analysts currently estimate the risk of a year-end lockout at 90%.
