Some of the more notable pitches (catcher's perspective):
Far to the right but no real vertical movement: Kyle Simon SL
Far to the left with no real vertical movement: Noe Ramirez FT
Positive vertical movement, some horizontal movement to the left: Matt Ramsey FF
Positive vertical movement, some horizontal movement to the right: Miguel Pena FF
Most negative vertical movement, some horizontal movement to the left: Jason Adam CU
Most negative vertical movement with horizontal movement to the right: Henry Garcia CU
Significant negative vertical movement and horizontal movement to the right: Brandon Maurer CU
Significant negative vertical movement and horizontal movement to the left:
Jason Gurka CU
Significant positive vertical movement and horizontal movement to the right: Mike Montgomery FF
Significant positive vertical movement and horizontal movement to the left:
Jonas Dufek FF
Of course, the biggest problem with using Pitch F/X movement is that it is often measured differently from park to park. That is, it is hard to compare pitchers from different teams using Pitch F/X movement because of all the biases in the data. The Arizona Fall League/Spring Training facilities are notorious for having some movement biases different from "normal" MLB parks. With this in mind, and using the MLBAM tags, this graph compares the average movement of each pitch type (just the major ones, I left out sinkers, splitters, etc.) in the AFL versus the MLB:
Of course, this may be because of the pitchers' themselves. Perhaps there is a different ratio of righties and lefties (which affects movement data) or the pitchers in the AFL on average just have different movement than an average MLB pitcher. Luckily, there were a handful of pitchers in the AFL in 2013 that also have pitched in the MLB. Using just their FF (I used the FA from FanGraphs for their MLB data) tags, we can compare how their fastballs "moved" in the AFL versus the MLB:
However, I think we should look at movement data from the individual pitchers on the AFL's Pitch F/X data's own terms, so below are graphs on the four seam fastball, slider, curveball, and changeup split between horizontal and vertical movement, labelled with some notable pitchers.
Ramsey and Adam show up again. What about sliders?
Malcom Culver is a 23 year old reliever in the Royals' system coming off a nice year in A+.
It is interesting that Kyle Simon's slider appears a couple of times here, getting very little vertical movement at times, and a decent amount at other times. Will Roberts also seemed to vary his slider as well, getting moderate movement to good movement, while his horizontal movement was mostly moderate. Alex Sogard seems to vary his horizontal movement with his curve slightly:
Ryan Harvey is a Rangers' 2012 18th round pick that, despite a large volume of walks, pitched relatively well in relief in A+. Vertically, we see that some curves, perhaps those of Mike Morin, were misidentified sliders.
Matt West shows up again, showing good movement both horizontally and vertically. West is another Rangers reliever, missing most of the last two seasons with injury. West shows up again when it comes to changeup movement:
When it comes to vertical movement, I am not entirely sure why some, with Kevin Vance's name appearing around some of them, have negative vertical movement:
Trevor May, the former highly rated Phillies prospect that was a part of the Ben Revere trade appears with Royals' Noel Arguelles, a high bonus pitcher that has struggled with command.
