"At Level” Player Requirement: Adult 18 & Over teams must have a minimum of 6 players for five-line leagues or 4 players for three-line leagues who are rostered at the team’s NTRP level by the time the first match is played. Teams are required to maintain the required number of “at level” players throughout the entire season, including postseason play. If a team does not have the required number of “at level” players at the time of any match, that team match will count as a loss with all individual team matches being scored as 6-0, 6-0 losses. In any “plus” team (4.5+, 5.0+, etc.), up to two “plus” players may count as part of the total team requirement for the “at level” players. "At Level" FAQs
