60 game schedule for 16 teams in two leagues
The schedule is for two leagues with two divisions each consisting of four teams (16 teams in total). Teams play four 3 game series against each other team in their division, and two 3 game series against their interdivision opponents. There is no interleague play, and no all star game.
Series are generally Tue-Thu and Fri-Sun, with a handful of Mon-Wed thrown in for variation. There is one day each week with no scheduled games. I suppose you could add an All Star Game on one of those days if you really wanted to.
Enjoy!
