What happened: The MLB Players Association came out against the league's proposed draft overhaul, which would bar high school players from being selected and impose a minimum draft age of 20. The proposal has also drawn anger from scouts, agents and executives, according to reporting on the plan.

Why it matters: Banning prep players and raising the draft age would reshape how amateur talent enters professional baseball and could push more young players toward college or international routes. The union's opposition signals a contentious fight, as draft structure is the kind of issue that typically becomes a bargaining flashpoint between the league and players.

What to watch: Watch for a formal MLBPA response and whether the league advances or revises the proposal as negotiations continue.
