Ok, in my "category of losses" this is definitely embarrassing (the implosion in the 7th inning and no runs against their bullpen) and because it's a one run game that we COULD have won, it falls into the disappointing category, as well.
And the fact that Lohse stinks, this could also be considered a bad loss because that's a pitcher against whom we should win.
So, in total, this is one of the worst losses of the season. Not the absolute worst, certainly, but still one of the worst.
