Padres game will not be televised this afternoon

The Padres / Marlins game will not be televised locally. Which gives us a chance to listen to the manly voices of Ted Leitner and Bob Scanlan.

Remember: no local tv for today's 4:10 pm PT game vs. @Marlins. Watch live on @MLBTV or listen on @Mighty1090 and @XEMO860

FSSD tweeted Clayton Richard Super Fan, Luigi, that it's due to Fox's exclusivity agreement.

@LuigiPadreFan33 Marlins have to play the game at 5pm local, it's the exclusive national window for Saturdays, so the game cant be televised

Now I've never heard of this so-called "exclusivity agreement" so I tried to make some sense of it by trying to do a little bit of research on Wikipedia:

Currently, local broadcasts are allowed on Saturdays if the game starts before 1:10 p.m. ET or after 7:05 p.m. ET

I'm still a little confused because time zones confuse me. Wait, there's more:

Usually there are no other games scheduled at these times, except when a team decides not to change the start-time even after Fox drops the game in favor of a better match-up, which they can and often will do on a few weeks notice, particularly after the All-Star Game.

@sdutPosner Always the home club's decision. Marlins decided to keep game at 7:10 local and not televise.

So I'm just trying to figure out who we're supposed to blame? Fox for cancelling what might have been a nationally televised game? The Marlins for refusing to reschedule? Time Warner for not picking up FSSD? Time zones?
