From this AM’s Cincinnati Enquirer (I can’t find an online link to this article), it appears that four Reds games will be shown on Fox Sports Ohio during Spring Training:

3/7 3:00 PM vs Milwaukee from Goodyear
3/12 4:00 PM vs the Cubs from Las Vegas
3/17 4:00 PM vs Cleveland from Goodyear
3/24 4:00 PM vs Texas from Goodyear

Thom Brennaman and Jim Kelch will do two games, Chris Welsh will do three, and Jeff Brantley one. Jeff Piecoro and Jim Day will share “sideline reporter” duties. The March 7 game will be a joint broadcast with the Brewers’ Fox Sports North network.

In addition, WLW-AM will broadcast two games the week of 2/27 (the first week of games). Marty will call the 2/28 (3:00 PM) game vs the Indians and a 9:00 PM game on 3/3 vs the Dodgers. WLW will also broadcast two weekend games (3/5 & 3/6 then 3/12 & 3/13) before starting daily games on March 19.
