If you use an iOS device, you can AirPlay the audio from your iPhone to your Sonos One.
Thanks! However, we’re Android. Any other ideas? :)
Have you tried the MLB Alexa skill?
As far as I know, the folks at MLB have not set up on Sonos so far. If you wanted to petition MLB to do so, you could point them to the Sonos partners page.
Rather than pay MLB for another subscription, I listen to the ‘local’ radio station carrying the game on iHeart radio. In my case, it’s KNBR, and about half the time I use the Sonos app, and the other half the time I just use an Alexa device, and skip using the Sonos, since fidelity isn’t really required.
