I am a longtime reader/first time poster, and while I have basic knowledge on Sabermetrics, I'm certainly not an expert. I first started reading this board because of the poster, Tango Tiger, who wrote "The Book" which is one of the most complete stats books I have ever purchased.

Anyways, I am working on some research and I've developed a few rudimentary pitching stats to aid my research and I want to know if these can be, or have been used already. The reason I am posting here is because I used Tango's linear weights to help create some of my stats.

Essentially, I am trying to research the value of Walk Rates, Groundball Rates, Homerun rates, and Strikeout rates and how they relate to each other. More clearly, I want to show how each stat helps a pitchers overall value. I'm basing most of my work around BABIP, XBHIP%, and the linear weights assigned to the offensive categories of singles, doubles, triples, HRs, and BBs and applying those to the aforementioned rate stats. I'm using strikeouts mainly under the idea that every 10 strikeouts prevents 2.9 hits (simply preventing 10 balls in play, which would equal about 2.9 hits). Combining all these factors against league averages I find just how much "damage" a pitcher has prevented. Ultimately, based on as many component stats as I can use and applying them to the adjusted laws of BABIP and XBHIP% and then applying those stats to the linear weights.

My questions:

1) Well, if I'm making sense to anyone, has this been done before?

2) Can you apply Tango's linear weights to pitchers? I assume you can, because I'm simply applying them to the offensive categories they would give up

3) Is there any research/data you guys know of that shows that groundball pitchers can "control" extra base-hits? In my research I have found that they are the one group of pitcher's that consistently limit extra base hits on balls in play.

4) Is there any concrete data about HR/9 rates? Most of what I have found shows they flucuate a great deal, although I haven't taken any park factors into consideration, which is especially important in HR rates

Sorry for the long-winded post, and thanks in advance for any help. Please ask if you want me to clarify anything, I realize I might not have explained myself that well
