Bleed Cubbie Blue has the full schedule listed, and it’s worth a look. In summary, it’s looking like 63 games on WGN, 4 on ESPN (more will get added through the season), 8 on Fox, 79 on CSN and CSN+, and 8 on WCIU.
It’s all subject to change, of course, and there will be a few games, at least, on the new MLB Network.
