New Stat: wOBA - BABIP

[Will James]

This stat I just made up this afternoon. It's wOBA - BABIP. I'm not sure what the results even mean. Basically it is the best all around offensive metric for results in wOBA then taking out the luck factor in BABIP. So maybe this stat is really how hitters should be judged? What do yall think? Posted on SP but wanted to bring it here as well. Here are the numbers.

What are you attempting to find out? Are you trying to find out how lucky our hitters are?


It seems to me that it's a little redundant since wOBA attempts to try to capture all of that already.

I don't think wOBA has anything to do with luck. It's just a more accurate OPS, basically OPS on an OBP scale.

Basically what I'm doing is looking at the wOBA which is totally results oriented and then saying okay but how much of that is luck. So by taking away the BABIP which is what is used to determine luck, it comes out to those numbers.

I don't really think it is as simple and cut and dry as that. There is probably some number that wOBA would have to be multiplied by before subtracting the BABIP, and that would take some advanced math to find. But I think that this model, wOBA*X - BABIP has legs to be a very relevant statistic.
