@mathowie The patter of the announcers is entirely different and is much more telling of a story instead of filling in gaps where the picture is slow. When I was going to a bunch of Diamondbacks games while living in phoenix, I'd see guys who would be in the stands with portable television sets tuned into the game they were attending and also with an earphone listening to the same game on radio. They wanted to be in the park where it was happening, but they wanted the stats and close-ups from television, and wanted the patter from radio.
The local station that carried the ball game there had a 5.1 surround sound that they did the game in, with the center speaker being the announcers and the rest of the surround picture being the actual sound of the ballpark. I used to tune into that and turn off the center speaker and just sort of virtually be at the ball park if I couldn't be there in person.
This has been my TED talk on how sound and baseball can be weird.
