Article: Glen Perkins and the modern pitcher

Featured Replies

Thank you Parker. Fun to read that we aren't the only ones obsessing about stats.

That was a great article. I think that Bannister was kind of the first one to talk about advanced stats and thinking through what he did on the mound. I know that Max Scherzer is another one who acknowledges that he jumps into the stats. I'm really glad that you got some time one-on-one with Perkins and were able to answer these kinds of questions.

Great to see athletes not being immediately dismissive of this. I wonder who most influenced him, in accepting an analytic POV.

 

I remember Glenn Gostick going over his hand-typed sheets of stats at the local SABR confab in the '80s. In every generation, there are always at least a few trying to do this. Maybe it's gaining more traction.

Nicely written, great interview.

Glen Perkins is going to be my new favorite Twin since Denard was traded. Let's see a sub 3 ERA, lots of Ks, and saves!!

Settle for a win instead?

Sorry to rain on the parade, but if he sustains a pitching-level like today's outing he will be gone by July.

I think that the big problem with f/x data and grading umps based on this, is that the plate has depth. Like Perkins said, where umps miss his strikes is when they catch the front part of the plate and the catcher doesn't end up catching the ball behind the plate. I wonder if f/x data really reflects the depth of the plate. I know that the ball/strike stuff that annoucers use doesn't always seem to reflect that. I know that some people here talk about framing pitches, but where the ball is caught doesn't always reflect where the ball was when/or if it crossed the plate.

 

I know umpires are being graded on their ball and strike calls. I hope that the data used isn't based on where the ball is caught.

I was happy with that :roll:

This was a fantastic read!

Pitch F/x tracks where the ball crosses the plate.

It's incredibly accurate. Within 1/2", and 1 mph at most ballparks.

Here is a good link with data measuring it's accuracy at each ballpark. (And this report is almost 2 years old, they are constantly tweaking it for accuracy, so it's safe to assume that it's even more accurate today.)

Yes it does. Pitch F/X rules a pitch a strike when the ball crosses any part of the plate in the zone.
