Chris Carter Addendum

Earlier today after he was dealt to Houston, I did a piece on Chris Carter and how his power should spike with his new home ballpark. I used the Katron.org balls in play information to outline three batted balls from Carter that would’ve been home runs in Minute Maid Park. It was meant to accentuate the point regarding his likely power improvements in his much friendly environs, but it was greatly flawed. You see, the Katron dots are where the ball is fielded not where it landed. I knew this in the recesses of my mind, but I never gave full thought to the notion and what it means when analyzing this kind of data.

Here is the legend for the Katron data:

The problem comes in that we don’t know the hit type of singles, doubles, triples, and home runs. So I absent-mindedly assumed (never assume, kids) that the doubles were hit in the air either as line drives or flies. They were not. After getting some education about Katron and the potential flaws with using the data as I did, I went back to the video and found out that my particular examples show just how dangerous using the data as I did can be when the dots represent where the ball is fielded and not where it first hits the ground.

First, let’s look at the doubles:

See the problem now? I apologize for that, I simply didn’t put together the inherent flaws of using the data like that. It’s 100% my fault, though, so I’m not crapping on the folks over at Katron.org as it’s even there in bold below the charts:

Every location is where the ball was fielded by a player, not where it landed. You better read this Paul Sporer you stupid dummy. 

That may not be a fully accurate quote from their site.

Perhaps if I had been reading my now-BP-colleague Sam Miller a year ago when he was writing at the OC Register, this all could’ve been prevented.

Hey, at least the flyball I highlighted doesn’t have the same issues. There is no guarantee it would’ve been out in Minute Maid, but we see the 367 sign behind Josh Hamilton when he catches it and we know that Minute Maid is 315 for a large portion of leftfield known as the Crawford Boxes.
