MLB Network posted their Spring Training schedule on Tuesday night and the Pittsburgh Pirates will be featured 15 times total. A couple weeks ago, ROOT SPORTS announced that they will show 12 games this spring and there is a lot of overlap between the two channels.
Here is the breakdown of games shown on MLB Network, with an asterisk next to the live games, and ROOT next to games on both networks. All the games are in March, so I just included the date next to the game.
4. vs Twins 1PM* ROOT
7. vs Phillies 9PM ROOT(tape delay from 1pm that day)
9.
