It's like watching a different game when you see baseball in HD. Besides the great picture quality, you get the benefit of the widescreen (16x9) view. You can see so much more of the game.
Thanks for the heads up Limey- the game on 8/25 vs. the Brewers was listed on the TWC site as being in HD, yet it wasn't (there were a couple of others this month that were listed but were never shown). I really hope they give these three games.
ETA: Time Warner and FSN did get it right this time- The pre-game show is already on channel 302. Thanks again Limey, I would've never checked tonight.
