There were approximately 8856 pitches by 110 pitchers correctly and fully tracked by Pitch F/X in the Arizona Fall League in 2013. On the blog, I would like to look at all the pitches as a whole, along with some individual hitters and pitchers. This is the first post in the hopeful series. First, I wanted to look at how pitches were located by individual pitchers. So the following picture (click to enlarge) is the average location of all the pitches thrown by each pitcher. The entire graph is the strikezone:
Lefty Jarret Martin was an extreme arm side pitcher in the AFL, and he has really struggled with walks in his career, currently with the Dodgers after being drafted twice by the Orioles. Chris Bassitt, a 6-5 24 year old with the White Sox, was an extreme arm side pitcher as a right-hander. He is coming off a strong season where he pitched well in his first taste of AA. Two pitchers that stand out as being pitchers that throw the ball slightly below the middle of the strike zone on average, along with pitching both sides of the plate equally, are Vidal Nuno and Chad Rogers. Nuno is a control specialist that had some success with the Yankees this year while Rogers is a former 28th round pick in 2010 by the Reds. The undersized right-hander was a full time starter in the upper minors for the Reds in 2013 and had a solid year, despite not having flashy peripherals.
Since we are talking about mostly young pitchers trying to refine their stuff and command and make it to the Majors, I thought it might be at least interesting to look at the wildest pitches thrown in the AFL out of the ones tracked by Pitch F/X. I broke the wildest pitches into two graphs, fastballs versus non-fastballs (using MLBAM tags). Then for each graph, I looked at the pitch furthest to the left, the right, and highest and lowest. Here are the "wildest" (not counting intentional balls) fastballs, labelled with actual MLBAM tag:
How about non fastballs?
In general, here were the average pitch locations, regardless of handedness, of each pitch type in the AFL in Pitch F/X games in 2013:
