The statistic makes no attempt to adjust for outcomes on balls in play or home runs per flyball, which I find less troubling when viewing an entire career.

Any issue with this method on that basis must also apply to W/L and ERA. You can certainly hold that view. I just wanted to point that out to those who don't follow all the arguments as intently as others.

If you use it for career numbers or atleast over several seasons it will provide some good information, Matt Cain for instance is a very good pitcher but he is saddled with a very poor offense. I will look up Snells LD%, but it is possible for it to be high enough to affect his BABIP and be indicative of how he has pitched. His xBABIP may still be around 330 which is still not very good. This will never replace FIP, but can be used like FIP/ERA comparisons.

First, Ian Snell has the lowest Win%. He also has the highest BABIP in major league baseball making him unlucky. Im pretty sure if he was league average in that category he wouldn't have the lowest Win%. Witch makes me think this takes into account hits for pitchers instead of say GB, FB, and LD (like tRA) witch makes me not like it. Also, Duchserer, who has been one of the luckiest pitchers, is high on this list. This seems to be looking at hits aloud, instead of the more accurate measure of GB, FB, LD.

The even awesomer thing is that it works for hitters too! If I am not mistaken it is a completely neutral stat as well, no need to adjust for park, league, or time period.
