I'm not sure what to name this term, but I think it's a good idea.
In h2h play for instance, when you look at the score of one of your opponents pitchers games and you see they lost 6-4, so you think to yourself, nice, their pitcher got lit up tonight! But then you go to the box score and see 6IP, 6H, 2BB and 0ER, but 4 unearned runs. There's gotta be a term for this for when you get your hopes up, but they are quickly shut down because of the 0EA performance.
That happened to me with Santana tonight.
