This is the blackout rule from mlb.com:
Regular Season Weekend U.S. National Live Blackout: Due to Major League Baseball exclusivities, live games occurring each Saturday with a scheduled start time after 1:10 PM ET or before 8:00 PM ET and each Sunday with a scheduled start time after 5:00 PM ET, will be blacked out in the United States (including the territories of Guam and the U.S. Virgin Islands). In addition, in the event of circumstances that produce a programming conflict or change in schedule, the above blackout windows may be subject to change. If you are an MLB.TV Premium subscriber outside of the United States, each of these games will be available as an archived game as soon as possible after the conclusion of the applicable game. If you are an MLB.TV Premium Subscriber within the United States or an MLB.TV subscriber in any territory, each of these games will be available as an archived game approximately 90 minutes after the conclusion of the applicable game.
Whoever wrote this must have been drunk because it's horribly written. The blackout period is dependent upon the start time of the Saturday game. It's not a fixed blackout window. Saturday games start at 1:00, 4:00 and primetime. The blackout window depends on that. Also, they say the games are blacked out in the United States but no say anything about internationally. Also, why is there a distinction between when archived games are available? If the game is available approx. 90 minutes after the conclusion of the game in the US, isn't that the time, ie "as soon as possible", it's available internationally?
