This is cool
Really neat piece at THT on pitch identification with the Gameday fx system.
And the author has put together charts to show, for individual pitchers, how much their individual pitches break and at what velocity. He breaks down several pitchers as part of the article, and attaches PDF files at the end for about 150 others.
Really neat stuff...for example, with Brandon McCarthy, his fastball has almost no "tailing" action, but is among the most extreme in terms of "rising" (which, of course, is a misnomer, since fastballs don't actually "rise," as the author explains), while his curves almost all have almost the same horizontal break, but with a great deal of variation in their vertical break.
C.J. Wilson, meanwhile, has quite a few pitches that are the velocity of sliders, but which have almost no horizontal or vertical break, which (from reading the article) could be the famous gyroball.
Really neat stuff...check it out...

Awesome
Verlander is also interesting. His fastball and change are in the upper left quadrant as expected. It also looks like both his curveball and slider have the exact same break, they are just different speeds.
Also, to make sure I understand this correctly, the reason the changeup breaks down is because it is slower, so gravity works on it more. It has the same spin as a fastball so if it was the same speed, it would act the same, correct? So if this is true, wouldn't Verlander's curveball appear to break downward more than his slider since it is a slower pitcher?
About Verlander
- He is throwing a slow curve in the low to mid 70s and a slider that sits around 85 mph. The orange would be the curve and the red would be the low to mid 80s slider, which would also explain the few green (85-89 mph) green dots in the plot.
- He is throwing one breaking ball, a power curve that sits in the upper 70s and lower 80s, which would explain why there is about an even split between the green and red and why they have identical breaks.
juvenile humor quote of the day
Robinson Tejeda's charts is very
The charts
(The article talks about how the analysis doesn't say anything about a pitcher's command).
Tejeda could have the same charts and still do a decent job of keeping the ball down if he had better command of where he wanted to throw.
Tejeda
Sinking fastballs
Yup
I think I first started thinking about this after playing Wii baseball, where the only way to tell that a pitch is a splitter is by recognizing that it has very little spin.
Yep
those splitters

His green pitches are his four seam fastball, which has less tailing action then a lot of other pitchers. The red pitches on the left of the graph are probably a two-seam fastball, since they are slower, would sink more and have more tailing action then his four-seam.
Moving to the right side of the chart, we have his slider/cutter which appears in red, and his curveball which is orange. Both appear right about where they should be.
This all meshes nicely with the Baseball America scouting report on him, which says his fastball is in the upper 80s and can touch 90 mph (hence the green dots). Says he also throws a cutter and a curveball. They make no mention of a two-seam fastball, but the fact the pitch has tailing action, is slower than his four seam and shows up where we would expect a two-seamer to appear, lead me to believe he is now throwing one.
My favorite chart
Yeah

Loe's is interesting
Yep
His breaking ball generally is what I would describe as a frisbee slider, which the chart certainly seems to confirm.
Hmm
