I’m watching this game once again “after the fact,” so I don’t know what the syncing between the radio feed and the picture feed was on MLB.TV but for me after the fact, it’s perfectly synced. Others have said this is not the case for them.
This is the first time this year when it has been perfectly synced, but the game has been over for hours. The original advertising has all been erased so I guess I’ll only find out how good this whole process is when I watch the game tomorrow.
