Five games are currently on the TV schedule. They are as follows. This is from the Giants website and one maybe in error.:
March 7 - Texas - CSN Bay Area HD
March 11 - San Diego - KTVU
March 12 - Los Angeles - CSN Bay Area HD
March 28 - Oakland (at AT&T Park) - CSN Bay Area HD

There will likely be other games televised on the MLB Network. Friday, February 25th is listed on the MLB Network website at 3 PM (ET) as Teams TBA. The only game between two MLB teams that day is Diamondbacks vs. Giants at that time so expect this game to be on TV.
