Frontier League Roster Rules

Club rosters will be composed of a minimum of 22 active players and a maximum of 24 active players. During the off-season, clubs will be allowed a maximum of 34 players under contract and on the active roster. No player may be 27 years old prior to January 1 of that season with the exception of one Veteran Player (see below). Each club must carry a minimum of 9 rookies (22 man roster), 10 rookies (23-man roster) or 11 rookies (24-man roster). A team may only have one Veteran player on their active roster at any time.

Players are to be categorized in the following classifications:

Rookie-1 Classification: The Rookie-1 sub-classification will be for players who made their professional debut in the current season and therefore have no prior experience.

Rookie-2 Classification: The Rookie-2 sub-classification will be for players who held the Rookie-1 sub-classification in the previous year in the Frontier League (regardless of the number of at bats, innings pitched, or pitching appearances) or began their professional career during the previous season.

Experienced Classification: The Experienced classification is for all players who do not meet requirements to be classified under the Rookie or Veteran classifications.

Veteran Classification: The Veteran classification is for a player who is over 27 years of age but is not yet 30 prior to January 1 of that season. The player must have been listed on a Frontier League active roster or injured list for a total of 100 regular season games combined during the previous two seasons.
