MLB games have never been a part of Sirius and the Best of XM.
That is correct. It is one of the few things that requires an XM radio to get. And, so, we only purchase cars that have XM radios included or can be added (good for GM and Japanese manufacturers, bad for Ford and German manufacturers).
I wouldn't hold my breath if I were you. Do you have a smart phone? If so, you might be able to download the MLB at bat app and listen via an auxiliary input (my not so eloquent solution).
