Minor League Comps

I did a bunch of minor league comps using the statistics that KATOH was interested in based on 2018 minor league performance.

RENGIFO

I was a big fan of Chris Mitchell’s KATOH predictions at FanGraphs and spent a bunch of time coming up with an offense-only version. I’m calling it RENGIFO.

RENGIFO is weighted 70% current year performance, 30% previous year performance, and if a player played at multiple levels in a year, weighting is given to IP or PA at that level. I used the years 1980-2007 to generate my coefficients, and found pretty similar significant statistics at each level as Mitchell did in the initial version of KATOH. The one issue I’ve had is with A- offensive results - the system seems a lot more accepting of RK and A level results than A-. I’m not sure why the system is so dismissive of A- offensive performance, but I think I will put in more research on why next offseason.

I ported the Scoresheet Out of Position Tool over to JavaScript.
