Framing by Battery

by jorgenswest on 07-16-2014 at 09:01 PM
Baseball Prospectus has pitch framing data organized by battery.

Framing data by battery

The data looks at pitches where the umpire needs to make the call and compares actual strikes with predicted strikes.

While looking at splits creates small sample sizes, I wondered if it would be clear that Josmil Pinto's framing skills are significantly worse than Kurt Suzuki.

The natural place to start is Glenn Perkins.

International Signings: How many of the top signings make it?

by jorgenswest on 07-03-2014 at 02:29 PM
The Yankees have poured millions into international signings this summer. In doing so they will give up the right to sign players to more than $300,000 over the next two years and pay a large tax. Is it worth it? How easy is it to determine the best players to sign at age 16?

In order to help answer that question I went to look at the top signings of the 2007 and 2006 seasons. Players signed in those seasons have now had 7 or 8 years to develop. They needed to be put on 40 man rosters

Twins and Catcher Framing

by jorgenswest on 06-18-2014 at 10:44 AM
Glen Perkins talked about Josmil Pinto and his ability to frame pitches. He didn't mention Kurt Suzuki. I guess he wasn't asked. Nor was he asked about Ryan Doumit in previous years.

Since 2011 it has been debated about the Twins decision making on catcher and defense. At best, they are waiting to see if the data that has been available for many season has validity. At worst, they are ignorant and that ignorance shows in their roster decisions as well as their development of catchers

With the signings of Kubel, Bartlett and Guerrier, comments overwhelmingly went like these below.

This isn't low risk..... it's NO risk
Minor league deals don't cost anything.
What's the negative??
Minor league contracts have zero downside.
Great move to give the Twins one more option without any risk whatsoever.

Some Samples No Longer Small: Pitchers

by jorgenswest on 05-03-2014 at 01:16 PM
Sample sizes for a few ratios are becoming large enough to consider. For pitchers, strike out rate stabilizes at 70 batters faced and ground ball and fly ball rate stabilizes at 70 balls in play. By stabilizing, that doesn’t necessarily mean it is the new expected rate. It does mean that any significant changes from previous year cannot be written off to small sample size. For minor leaguers a drop or change likely coincides with a step up in classification and the necessary adjustment. It is also
