The last preseason game. And, according to MLB Network:
MLB Network's simulcast of the Seattle Mariners at San Francisco Giants Spring Training game Sunday, April 4, will be available in the Giants’ home television market live at 12:00 p.m. PT/3:00 p.m. ET. MLB Network will carry FS Northwest’s call of the game.
MLB Network is available in the Bay Area on Comcast channels 412 & 729 (HD), San Bruno channels 44 & 449 (HD) and DirecTV channel 213.
For as much deserved crap as MLB gets for their strange, unjustifiable blackout rules -- try getting an MLB.tv feed of the Giants in Vegas or Hawaii -- at least they know it's silly to enforce them for exhibition games.
Also: This is a chance to get your Ron Fairly on! Yaaaaaay! Yaaaaay! Yay. Yay?
