Sling TV, the live streaming service owned by Dish, said today that it will add four NBC-CSN regional sports channels on April 2, in time for the 2017 Major League Baseball season.

The channels are CSN California, CSN Bay Area, CSN Chicago and CSN Mid-Atlantic and they will be available at no extra cost to all ‘Sling Blue’ customers who live where the regional nets air without blackouts. (For instance, Chicago subscribers to Sling will get CSN Chicago, but not the other three CSN channels.)

Amazon’s Echo w/Alexa: $179!

Sling TV offers two basic tier packages — Orange, which starts at $20-a-month and includes ESPN and roughly 30 cable networks; and Blue, which starts at $25-a-month, and includes more than 40 channels including live network feeds in select markets as well as several Fox channels.

While Sling is promoting the addition of the NBC-owned CSN regional sports channels as a boon for baseball fans, CSN Mid-Atlantic does not have the broadcast rights to the local MLB teams, the Baltimore Orioles and Washington Nationals.

Those teams air exclusively on MASN, an independently-owned regional sports channel in the Baltimore-Washington area. Sling TV does not carry MASN.

However, CSN California airs the games of the Oakland A’s; CSN Chicago airs games from both the Chicago White Sox and Chicago Cubs; and CSN Bay Area has the regional rights to the San Francisco Giants games.

Sling TV already offers Fox regional sports channels in the local markets where they air without blackout.
