It's actually on national TV (FS1). But I love the Mets announcers, that is the one thing I will miss the most about not having MLB.TV. Any homer tendencies they have (and IMO they are minimal) are balanced out by the fact that all three of them are just great at their jobs. Nobody on the Phillies (TV) crew approaches their level.
(Now also seeing Baseballcat's post, yes, Smoltz is not an improvement!)
