BB/9 out of whack Topic

I've only abused Moore once in an OL/CL and once in a theme league. In a current CL through 15 games and 12.1 IP he has a 1.42 BB/9. So, the abuse represents just 10% of his uses. Or, in Northrup's case, about 39 seasons of abuse, which is actually fairly likely.  Even with the 2.85 ERA. Assuming all of the 39 uses had ERAs of 7.5, the other 348 uses would still have a cumulative ERA of 2.28. Showing that the ERA is not indicative whatsoever of abuse or not. In fact, I've had many abused pitchers have ERAs below 7 and some below 4, even. And I've had a mop up with a near .500 OAV, 4+ WHIP, and 25+ ERA win 20+ games. I think Northrup, and the other similar pitchers, BB/9 look bad solely becuase of abused seasons and from them being low IP pitchers which lends them to greater fluctuations of luck (within their acceptable range of stats depending on who they face).

Here are two examples of how depending on how the circumstances surrounding a pitcher's abuse, the stats can be very misleading (from a recently finished OL and from a recently finished FGY7): Despite being severely more abused and almost equally as bad to begin with, Bergman's stats actually look halfway decent. Though he wasn't facing the same hitters and had a horrid defense behind him, the extreme cases such as his can be quite useful in demonstrating a truth that is harder to see in not-so-extreme cases.

Interesting guys.

It turns out there were 25 pitchers with some bad data in the game. They included 1918 Toney, Northrup, Adams. We have corrected that data today.

The rate at which a pitcher walks hitters is irrelevant of role. It's all about their actual rate and fatigue and opponent.

Good job!  So I guess I can expect my Northrop's 3.93 bb/9 to go down!

A question, what weight is given to the fact that in 1885 and 86 it took 6 "balls" to walk a batter and 5 in 1887 and 88?

It would be nice to know who the 25 corrected players are.

So does that mean pitchers listed as SPs in the database are not penalized somehow when used in relief?

Time to tweak the cookie recipe.  Much as everyone would like to think this is all about underperforming pitchers like Northrup, Adams and Toney (maybe Rasmussen and Eck?) there are bound to be some overperforming pitchers in that group of 25 as well.  Wouldn't it be ironic if Joss `08 was one of them?
