daBelow are the full rosters, including the coaching staffs, of the teams of National Pro Fastpitch softball league. All teams are allowed at least 18 and up to 23 players on their roster. Per Commissioner Cheri Kempf's tweet, NPF contracts expire in February, therefore the extension of a contract "through 2018" means the player is only contracted to play through the 2017 season, with the contract expiring the following February. The final year listed for a player on the rosters below is the final season the player is under contract, with expiration in the following year's February.
