Comments on: Biggest BAbip advantages so far this year http://www.baseball-reference.com/blog/archives/12322 This and that about baseball stats. Tue, 16 Jul 2013 17:01:55 +0000 hourly 1 https://wordpress.org/?v=4.6 By: obsessivegiantscompulsive http://www.baseball-reference.com/blog/archives/12322/comment-page-1#comment-124639 Tue, 28 Jun 2011 17:41:55 +0000 http://www.baseball-reference.com/blog/?p=12322#comment-124639 The way the article is written, it seems to assume a regression to .300 BABIP mean, which most pitchers regress to because that is the talent level across the majors. Hitters, however, regress to their established baseline, as the other commenter noted.

Most analysis of this sort usually use the hitter's career or 3-year average for BABIP, as the established baseline. Players regress to those means, generally.

Also, typically, speedsters like Fowler (or Ichiro) can hope to maintain high BABIP, whereas the slow guys on the list, usually not so much. Still, if they can hit well (Pablo Sandoval has high BABIP despite un-skinny and un-speedy body), that is also another way to attain high BABIP.

BABIP for hitters is mostly useful in comparison to a hitter's established baseline, not his overall BA.

A good hitter with a .330 BA isn;t likely to have a .440 BAbip.

I just ran a report looking for the best BAbip since 1961, and I used the low standard of 251 PA (half of what it takes to qualify for a title).

I found only 8 players with a BAbip over .400, and of the top 200 players in the report; only 2 Jose Hernandez, 2002 and Jack Cust, 2010 would have made this list. Hernandez led the league in SO that year, and Jack Cust is, well you know Jack Cust.

It looks to me like we've got a bunch of guys who strike out a lot but haven't been hitting home runs. None of them except for Willie Harris have BAbips that are far outside their career norms. You might just as easily conclude that Cust, Hawpe and Hall should start hitting home runs more frequently, which will both bring down the BAbip - BA differential, and make their overall numbers look better.
