Pitch f/x Primers

by Sky Kalkman on Jun 2, 2009 12:15 AM EDT

Harry was on the radio earlier tonight and plugged some of the pitch f/x primer articles we're written. Might as well provide some links to them all in one place:

While we're on the subject, what other pitch f/x primers would you like to read? We're working on a tutorial for Harry's Excel file that will output neato flight path images.

I just have 1 question

How do you create a strikezone for your strikezone plots. I just save the image from excel and draw it on using paint or something, but it’s very tedious. Is there anything you can do with excel?

Here is what I do

Create a set of data set
1, 1.5
-1, 1.5
-1, 3.5
1, 3.5
1, 1.5

Then plot data and this set with lines with points. Will make pitch points look like a mess, but ignore until graph finished.

When done, select the crazy line between pitches and make it invisible.

I just use the box tool in excel

Select the graph, choose the tool (to ensure it is part of the graph when you copy it into paint or whatever for saving) and draw the box, use the coordinates TR listed. Then I make the “fill” color “none” so its transparent, and I’ll thicken the border to make it stand out.

One quick email to Harry this afternoon, and he’s already got the BtB gang working on a tutorial for his pitch flight graphs. Cannot wait for that. Thanks Harry/Sky/whoever will pen it for us BtB readers.

We'd be done already if it wasn't for your Tiger fandom :-)

I’d like prehaps an in depth tutorial on pitch classifications. Gameday’s data is wrong alot of the time and for Pitch FX to be an effective tool we must be able to properly classify pitches. Obviously, the general four (FB, CH,CB and SL) are easy but I’m wanting more info on Two Seam vs Four Seam or what classifys a pitch as a Cutter or whats the difference between Slider vs Cutter. Things like that would be greatly appreciated
