MLB rosters do not expand for the postseason as they do in September. Teams must select a 26-man active roster from their expanded 40-man roster. This includes any player on the 60-day injured list who has been reinstated. The reduction ensures high-stakes games have top-performing players and maintains competitive balance and strategy. Players not on the active roster can still participate in team activities and remain on standby in case of injuries or other emergency needs.
