baseball fans: is there any precedent for last night?

I'm not a baseball fan, but I did see much of last night's game in three bars (and experienced the cold miserable rain on the walks in between). What I understand is that (1) in the inning they were in, they could have called the game official prior to TB scoring a tying run, but (2) ending the game like that would be a controversial and unceremonious way to end the world series. If they would have called the game at the tie - instead of delaying it - they risked controversy because it would deprive Philadelphia of its opportunity to win the world series at home. But now it seems like the world series will be decided in a mini-game in which the Phillies get first and last bats.

I think the more fair route would have been to announce the inning they were would be the last of the game, and if the Phillies scored, they'd win the world series. If not, back to Florida.
