Importing Historical Pitchers: Is ERA used to generate ratings?
 

I'm curious as to if ERA is used to generate historical ratings for pitchers. I ask because I'm creating a Japanese roster set using MLEs. I made MLEs for the stats I thought were relevant (IP, hits, walks, HR allowed, etc...), but the pitchers are a little better than I expected. One thing I didn't do was adjust ERA, because I assumed it was not used to generate player ratings. But I could be wrong.

So is ERA used to generate pitcher ratings? And is there a source saying what stats are used to generate historical pitcher ratings?

ERA shouldn't have any effect. The only Lahman DB stats that will have an impact are IPOUTS, K, BB, and HR to my knowledge.

With early history pitcher imports and a scale rating of 1-10, all of my pitchers import with either a 1,2, or 3 in stuff, with most of them a 10 movement. The only real rating that seems variable is control, which can range from around 4 or so to 10. Is this normal ? Endurance seems pretty good too, but why all of the 2 stuff, 10 movement guys ?

Most of those early pitchers didn't strike out many, but they also didn't allow hardly any HR. That's how you get the low stuff/high movement players.

So later in history, pitchers with high stuff are more likely to K more batters than pitchers with low stuff ? Stuff and movement have always confused me. In real life, if someone told me a pitcher had "good stuff", I would think the pitcher had good movement on his ball. Why the two different ratings ?

Stuff correlates most directly with strikeouts and movement with allowing HR. At least, that's the way OOTP handles it. :)

Thanks. Thats good to know :)
