JomBoy makes a really good case that Devin was tipping his pitches. If the Mets picked that up, that's a huge, gaming winning advantage.
I don't agree we should trade Devin. If he's amenable to working on techniques that will keep him from getting too wound up in high leverage situations, I think he can be what we want in the biggest games of the season. He was pretty darned good in game 2. Of course, he'll need to work on not tipping his pitches too.
Finally, if Devin was tipping his pitches, who's to blame on the Brewers club for not catching it?
