- a lot of work has gone into the translation postprocessing of the PECOTA data, and GB%, BABIP, and defensive projections appear to have been significantly improved. There are still individual players that have interesting results, which we’ll continue to look at.
- a clarification: the column in the weighted means spreadsheet GB Out %, not GB%–that is, GBO/(GBO+AO), not GB/BIP.*
- four comparable players are now available, and their names are formatted to be easier to read.
- players have been added. Please comment on additional players we’re missing and we’ll get them in there too.
- player R and RBI now scale to the team run environment.
- a few pitchers have been assigned >30 starts, which was treated as a hard cap in previous runs.
We’ll keep you posted about additional updates… please let us know what else you are seeing in the comments.
* We would prefer GB/BIP, but for large chunks of our data, we don’t have GB info on hits, so we don’t have GB/BIP information. We can get GO data for a lot more pitchers than we can get GB data - so that’s what’s used. Once you get past pitchers with < 10 IP, the correlation between GBO% and GB% is about 0.96--pretty close to identical.
