According to MLB these are my blackout teams.
Chicago Cubs
St. Louis Cardinals
Minnesota Twins
Milwaukee Brewers
Chicago White Sox
Kansas City Royals
I currently get CSN-Chicago. Will I get any additional games on the added FSN's for these teams by adding the multi sports pack?
With a subscription to sports pack, you'll receive the Cardnails and Twins. You should already be getting the Brewers on one of the alternate channels and depending on were you are at in Iowa, you will also get the Royals on one of the alternate channels. At least thats the way it was when I was on E* and since i'm on D* now, I still subscribe to the sports pack and get every midwestern MLB team except the Royals, which is my team
Don't ask me why since KC is the closest MLB market to Des Moines that their games are entirely blacked out.
It's this way with the NBA and NHL as well, with the sports pack, you'll get the T-wolves, Wild, and Blues during the fall and winter months. That's in addition to the Bulls and Blackhawks on CSN Chicago.
As they have stated, you can only get the games on you normal local RSN. All other professional sports games on any other RSN channels would be blacked out. Otherwise the E* multi-sport package would be in direct competition with the out-of-market packages (like Sunday Ticket, Extra Innings, etc.)
Sounds like the Cards would be blacked out for you (even in the EI package) based solely on your location.
If you really want to see the Cards, you might consider "moving" to St. Louis. (Do a forum search if you want to learn more about "moving")
The entire state of Iowa is "claimed" by every Midwestern MLB team to be in their respective home TV market, so these teams are blacked out on EI and MLB.TV.
