w/r/t L/R: I see. In general, I think I agree, though the “shouldn’t we” made me think there was something wrong with the graph rather than a feature request.

The gameday data’s out there — you’re welcome to crunch it yourself. I thought presenting it like this w/o a breakdown was interesting enough to warrant the post. Maybe next time I’ll see if I can break it out L/R if that’s interesting.

Do we think Felix uses the same pitch selection for lefties that he does for righties? Does he have the same success with both? If the goal of this is to try to see what makes Felix a better pitcher, and we think pitch selection is a big part of that, and his pitch selection is different for different-handed batters….

If the movement on those pitches is the same, then varying velocity becomes a necessity for success.

How do we know this?

Couldn’t location be just as useful if not more useful than speed?

I tried, but the Babel fish translation no matter how I word it is “Establish the fastball.”

I want to print them out and study them. I want Dave to weigh in too, at length; preferably tremendous length. I think it’s exciting stuff, not because we haven’t seen the data before but because a picture really is worth a thousand words, and these graphs are almost like holding the entire game in your hand.

Great stuff, Derek.
