The National Hi-Lo Association is a retro league that plays in the hi-lo format.
In hi-lo, teams in the American and National Leagues are paired up in reverse order of finish – team with the best record in the AL paired with team with worst record in the NL, and so on. The combined players are then reduced into a single team.
Hi-lo leagues are smaller, half the size of the actual Major Leagues in that season, and do not require any drafting. Managers get completely different pairs of teams each year, so there are no long-term issues with teams dominating or being non-competitive. In subsequent seasons, managers will select from the new pairings based on their reverse order of finish in the previous year.
NHA is a Version 5.75 AIM computer league with a 36-week regular season of 162 games.
We have several openings for our upcoming 1964 season due to managers who have retired or had to convert to Version 6 for their other leagues.
Managers are required to already own or to purchase any version of the season disk being used. It does not have to be the most recent version of that season.
