Opp. SLG % For Pitchers

[Crash Course]

In Larry Dierker's book, he says that the two most important stats for pitchers are BR/9 IP and Opp. SLG%.

He says that a pitcher can give up HRs, like a Schilling or a Maddux, as long as he doesn't walk people or give up a lot of hits. On the flip side, he says that a pitcher like Glavine can give up hits and walks, and still win, just as long as he does not give up HRs.

I want to run numbers to test this out - but, it's almost impossible to get a pitcher's Opp SLG%, or even some of the components, like XBH allowed, or even just HR allowed, on most stat sources - online or not.

What don't "we" keep the stats, more often, on pitcher's Opp SLG% or XBH allowed?

That makes a lot of sense Crash. It seems to me that all the sophisticated analysis is done on hiters, and pitchers tend to just get measured by a few metrics or lumped in broad categories

I would love to see more info on those stats.

My big problem with DIPS is that I think a pitcher does in fact have some control over whether the balls that drop are singles or if they go for extra bases. I played around with a DIPS-type analysis where only singles were ignored, but I got sidetracked when the data wasn't as readily available as I hoped.
