They are quite different!
MLB does not block any spring training games!....So if you have the RSN networks package($14)....and that local RSN is showing it...you get the game....
MLB season ticket doesnt show spring training games, and wont let you log in on line to watch those sprint training games...So MLB season ticket starts on opening day......MLB wont block you from watching a spring training game if its being shown....UNLIKE all other sports channels when a pro game is on, you dont get it, just becuse its on a RSN channel.
