Robert "Vörös" McCracken is a prominent sabermetrician. He is most widely recognized for his pioneering work on Defense Independent Pitching Statistics (DIPS). This recognition eventually earned him a consulting position with the Boston Red Sox. Vörös is a nickname from his Hungarian heritage, meaning "red". Sabermetrics is the analysis of baseball through objective evidence, especially baseball statistics. ... In baseball, Defense Independent Pitching Statistics (DIPS) are statistics which measure a pitchers effectiveness based only on plays which are completely under his control: home runs allowed, strikeouts, hit batters and walks. ...

McCracken's findings implied that major league pitchers had relatively little control over the outcome of balls put into play against them. Specifically, McCracken found that the percentage of balls put into play against a particular pitcher that fell for hits did not correlate well across seasons. This implied that elements beyond the pitcher's control, including his defense, ballpark effects, the weather, and most importantly, randomness, had significant effects upon his performance. This theory flew in the face of conventional wisdom, but has been confirmed (at least in its simplest form) by many researchers.

McCracken asserted that pitchers have a lot of control over the defense-independent pitching stats, so I would expect to see substantial differences among pitchers in their career HBP, walk, strikeout, and homerun rates, even after normalizing all of these figures against the league averages for each season.
McCracken was quite correct in pointing out that Pettitte is not a pitcher who prevents hits on balls in play.
McCracken asserted that the team's IPAvg depended only on the park and the defense, but we've found that it depends on the park, the defense, and the quality of the pitchers on that team.
Sabermetric titan VorosMcCracken has returned from the wilderness, has a blog, and awaits the formation of a posse.
For those of you who are unfamiliar, Voros is the man behind Defense Independent Pitching Statistics (DIPS), which remains one of the biggest development in baseball research since, well, Bill James' beard was all pepper and no salt.
Voros is slightly less famous for impersonating my wife on BBTF five years ago, launching a minor meme that was famous among literally tens of baseball geeks for a handful of months.
