The Major League Baseball Players Association presented its latest proposal to owners, pushing for significant changes to roster rules. Key among these is an increase in active rosters from 26 to 28 players for the season's initial 15 days, aiming to reduce early-season player workload and create more opportunities for players to make Opening Day rosters.

The union also seeks to allow players to be placed on the 60-day injured list as early as the November tender deadline, three months sooner than currently allowed. This move would free up valuable 40-man roster spots. Furthermore, the MLBPA proposed limiting in-season optional assignments for players from five to three, directly addressing concerns about roster manipulation.

This latest offer, the MLBPA's third formal presentation, comes as the current collective bargaining agreement nears expiration in five months. Previous proposals have included adjustments to minimum salaries, pre-arbitration bonus pools, and luxury tax thresholds. The union also recently suggested a ban on player prop betting to curb gambler harassment.

The MLBPA's proposal aims to give players more stability and opportunity in the majors, contrasting with MLB's own proposals for a cap-and-floor system. The players also want access to club-controlled performance data to enhance transparency.
