Eventually what you want to be able to do with Pitch F/X data is to evaluate players. I have been looking at Pitch F/X data in the 2013 Arizona Fall League from several different perspectives, but have yet to look at isolated individual players. In this post, I wanted to look at a couple of notable hitters, not highly rated traditional prospects, but a couple of players I think are interesting, and see what the Pitch F/X data says about their tendencies during the AFL season (and perhaps, their offensive game as a whole).
Japhet Amador is 26 year old former Mexican League slugging 1st baseman signed by the Astros late in the 2013 season. Amador is most known for his weight, but he had some impressive seasons in Mexico. He
saw 160 pitches measured by Pitch F/X in the Arizona Fall League
His 32 swinging strikes is twice as many swinging strikes as you would want (at least compared to MLB league average), and that is going to be a serious problem if he is going to be a MLB player, so let's take a look at the pitches he swung and missed at
Moving on from Amador, I wanted to take a look at someone who had a home run explosion in the lower minors (32 homers in all in 2013) for the Rangers system, Ryan Rua. Rua saw 228 pitches measured by Pitch F/X in the Arizona Fall League, 28 of them for swinging strikes. Here are were they were located, labelled with MLBAM tags:
Finally, here are his average locations to give us a better idea of his hitting tendencies in the AFL
