Fair enough Matt. I hadn't considered that you were working off of body language instead of facial expression. I dunno if his body language said "unfocussed," but it certainly looked uncomfortable. I think Felix is still learning to make peace with the knowledge that some days he'll come out and have absolutely nothing. You're right, it's jarring to watch, and I bet it's pretty jarring for him too. The sooner he makes permanent peace with the demise of his fastball, like Kuma did, the better it will be for his pitch sequencing and his mental approach.
Sorry if I came out too strong on the other side of that one. Felix was the first baseball player I learned to love (Ichiro had already been here for a while when I became a serious fan). I may be a little overprotective of him. It's hard to watch him struggle like this, and I find myself hoping that no one makes it any harder by grumbling about how diminished he is. I imagine he's hard enough on himself that he doesn't need it from anyone else. Not that he's reading this blog, of course, so I guess I'm just trying to support an abstract principle.
