Eighteen and up, in five brackets
Arizona MSBL/MABL describes the Men's Senior Baseball League and Men's Adult Baseball League as the premier amateur baseball organization for adults 18 and older, and runs 18+, 25+, 35+, 45+ and 55+ divisions. There is a Vintage Division too, linked but not described.
Five brackets is a lot of league to keep separate, and it is the right structure: a 55+ game and an 18+ game are different sports played on the same field. The organization has been at this long enough to hold an Annual Managers Meeting at Tempe Diablo Stadium, which is a spring training park, and to keep a Hall of Fame.
What it does not publish anywhere is a team, a record or a field. The schedule lives behind a separate product called Proscorebook. High Cheese puts the divisions, the clubs, the schedule and the standings at one address the league owns, so the season is readable without a second login.
