The SSS BMO sim baseball league has an opening. It's Florida, but we have revenue sharing so being a small market isn't unbearable.
It's free to play. Control your line-up, make trades, sign free agents. Sims twice a day on weekdays, but none on weekends. If you check your team once a day on most weekdays you should be fine.
