Solonor's Groovy Computer Baseball League (SGCBL) has teams available. We are heading into 2035, our 33rd season after being founded in 2003. I'm not sure how many 14-year leagues there are out there, but if you're looking for an established league, give us a gander.

"Beings will come, Frodo. The one constant through all the years has been baseball. Middle Earth has rolled by like an army of Mumakil. It has been erased like a slate, rebuilt and erased again. But baseball has marked the time. This field, this game: it's a part of our past, Frodo. It reminds of us of all that once was good and it could be again. Oh... beings will come Frodo. Beings will most definitely come." -
