This looks like a good place to post this:
Does anyone know of a good, live online stream to watch the games? Not having cable television is hurting me.
postseason.tv is $5 for what they call "companion" coverage for the division series and ALCS. It is not the TBS broadcast but you can watch different camera angles streaming live and hear the tv audio. There is a "quad" view that shows 4 different camera angles at once. Quality I thought was pretty good. You can watch batting practice before the game as well.
