Three losses in a row is a blip. Four is a slump. These are arbitrary beginning-and-endpoints, but they're the ones I'm going with, and L4 is certainly nothing to ignore.
The problem: this is not a good pitching matchup. Not at all. And that's the last thing you want to see when nothing seems to be going right.
So, as always, Go Sox! But you'll forgive me if that comes with more than a little trepidation.
