If you want to rotate interleague schedules for your modern MLB setups you are limited to repeating 2013, 2014, and 2015 over and over again. I didn't like that, so I made up so new schedules that feature randomized matchups, while still preserving rivalry matchups.

The real life interleague matchups in 2015 feature playing the rival 6 times, 2 other teams 4 times and the other 2 teams 2 times. I couldn't copy that; the best I could do was playing the rival 7 times, 1 other team 4 times, and the other teams 3 times. There is 1 matchup (Yankees vs. Mets); I've got them going head-to-head 8 times and 3 times against the other 4 teams.

I think the hard part is done and I could make a bunch more if there is any demand.

These schedules should provide the proper matchups if you are using 2013, 2014 and 2015 and getting the proper matchups.

Edit: Since I did these, MLB changed the rivalries, so the 2019 schedule is not completely accurate for some rivalry games.
Only 2018 and 2021 are correct, now.
