MLB proposes cutting regular season to 154 games for the first time since 1960, with longer playoffs starting in 2029

Major League Baseball has put forward a new postseason and regular-season framework to the players union, proposing to shrink the regular season from 162 games to 154. MLB says the change would be implemented for the first time since 1960, ending a long stretch in which every team has played 162 games as the foundation of the standings and the playoff race.

Under the proposal, MLB would also require teams to play four split doubleheaders during the season. The league’s plan would have those additional game-days absorbed into the overall schedule, while also allowing the calendar to shift. MLB’s proposal would end the season about a week earlier than usual, a move that has ripple effects for both club planning and how the postseason window fits into the fall schedule.

The centerpiece for postseason football fans is the idea that the playoffs would begin later and run longer, beginning in 2029. The proposal also includes an element of matchup control, allowing top playoff seeds to choose opponents. MLB’s stated goal is to adjust the format and timing in a way that increases strategic payoff for regular-season performance, while also recalibrating how early-round matchups are set.

From the standpoint of competitive balance, reducing the number of games changes the arithmetic of the standings. Fewer regular-season contests can increase variance, because each win or loss carries slightly more weight in determining division and wild-card positioning. At the same time, because MLB’s plan would reward top seeds with selection power, the league is effectively tying late-season urgency to both playoff seeding and the ability to shape the bracket.

The scheduling component matters as well. Split doubleheaders are not new to baseball, but requiring four of them during a reduced 154-game schedule would likely alter day-to-day roster management. Clubs have to plan around pitching turns, bullpen usage, and the logistics of playing two separate games on the same date. Even when the number of games remains the same across teams, the distribution of those games can affect how teams allocate rest and intensity over the long season.

Whether the proposal becomes reality will depend on negotiations and how the players union responds to the tradeoffs. The union typically weighs total playing time, off-day availability, and the operational impact of schedule changes. MLB’s proposal also would need to be integrated with the broader offseason timeline and postseason programming, especially because a later and longer playoff would shift when teams and media partners operate on a near-daily basis in October.

For teams, the most immediate thing to watch is not just whether the number “154” survives bargaining, but how the postseason mechanics are negotiated and finalized. Because the plan would not take effect until 2029, club front offices are likely to begin framing roster construction with the possibility of a different end-of-season and a playoff bracket that may be partly shaped by seeding. The next step, for baseball fans, is to monitor what MLB’s full package includes beyond the season length and playoff scheduling, including the details that ultimately determine who gets to choose opponents and how that choice is structured across rounds.
