The Pecos League, also new in 2011 is a continuation of the Continental League. Most Pecos players were new to The Baseball Cube.
Because of the current design of the site's database, when a team change's leagues or league name, the continuation of the franchise does not continue. In other words, teams in the North American League, like the Calgary Vipers, will appear as a new team with no history. Meanwhile, Calgary's seasons in the Golden League and Northern League will remain as a separate team. I won't be changing this any time soon unless the Minor Leagues decide to do the same thing.
TBC now have complete independent League statistics since 1999.
