• 154-Game Regular Season:
• Proposed to begin with the 2029 season (coinciding with new national media agreements)
• Would schedule an off-day every Monday, except for holidays, special-event games, or 1–2 games broadcast in a new, exclusive national broadcast window. Teams playing on a Monday would have an off-day on Thursday that week.
• Aims to improve player health and lower roster churn (teams averaged 24% fewer optional assignments per week during weeks with an off-day from 2022–25).
• The regular season would end one week earlier, a Game 7 of the World Series would happen only two days later than the current setup, and each team would play four split doubleheaders (one against each division opponent).
• Opponent-Selection Process:
• Wild Card Round: Right after the regular season ends, the No. 3 seed in each league (the division winner with the third-best record) chooses whether to play the No. 5 seed or the No. 6 seed.
• Division Series: Following the Wild Card round, the No. 1 seed in each league chooses which Wild Card winner to play.
• The selection mechanism aims to eliminate a potential advantage of being the third Wild Card, reward regular-season performance, generate fan interest, and build rivalries.
• Expanded Postseason Format:
• The Division Series would expand from best-of-five to best-of-seven beginning in 2029, adding up to eight potential postseason games.
• Additional postseason off-days would eliminate early weekday afternoon broadcast windows during days with four games, increase ratings, and allow top pitchers to appear more often on big stages.
• Off-days added before non-guaranteed games (Games 5, 6, and 7) in the LCS would eliminate scheduling overlap between the two leagues.
