Rain delay + Final 4-1 in Top of 5th + Over Pick = Loss??

Not sure what the rule is on the over / under pick but it says I lost. The game got called in the top of the 6th due to rain and it was 4-1. Thats not fair. I thought it had to go 7 or 8 to do that. Can someone tell me why I lost? This is my survivor pick I'm talking about... Thanks.

because it was an official game

A baseball game, as per MLB rules, is official after 4.5 innings.

this is not a book

then why is the nats/phils over 11 a push, the score was 7-5 when game was called in 6th, it's an official game and obviously over the total.
