Not much info yet. Seeing what I can find.
MLB.TV has a schedule (partial?) of games.
Reds vs Mariners Mar 12th
Reds vs White Sox Mar 25th
Reds vs Mariners Mar 29th
The Cubs Marquis network is televising all home games. They will probably show up on MLB Network. They play Reds at home once.
Sun March 21st.
The White Sox are also broadcasting all home games.
Thursday March 25th will already be available on whitesox.com at a minimum.
I've seen indications that Dodgers will broadcast ALL games, If so they play the Reds March 3rd and 9th.
