Go to this page about an hour before first pitch and find the Mets feed. https://www.reddit.com/r/MLBStreams/ You'll get a pop up add or two and then voila - baseball. Legality aside, MLB, SNY, and the Mets have conspired to prevent me from watching my favorite team unless I subscribe to a major telecom carrier, which I no longer do. So I will use these streams, and my Chromecast, to cast games to my big ass TVs all season.
