A couple of years ago, Chris Dutton and Peter Bendix did some research on batted-ball data and created a metric called xBABIP (“expected BABIP”). xBABIP dispelled the myth that BABIP was primarily a function of “LD%+ .120.” Rather, as Dutton and Bendix found, BABIP was better explained as a function all batted-ball types and ratios with speed/power/strikeout considerations.
Last year, Derek Carty and Chris Dutton debuted the simple xBABIP calculator on THT. This tool has empowered users to determine a player’s xBABIP and compare it to their actual BABIP. Therefrom, one could forecast a hitter’s expected batting line, assuming all the input ratios were to remain constant. Over the course of 500+ PA, these ratios tend to be significant, though conclusions can still be drawn at the 300 PA threshold (we’d really only be waiting on IFFB% stabilization).
For all 270 hitters who accrued 300 or more plate appearances this season, I applied the xBABIP formula (by park) to determine each hitter’s expected batting lines. In short, what I have created is a spreadsheet of “what you can expect as a baseline for production in 2011, assuming all else remains constant.” In other words, this is how these hitters should have hit in 2010. …

For players that played part of the year with the White Sox I got their BABIP numbers from statcorner. All the numbers are for the time they played for the White Sox:
Mark Teahen had only 262 PAs.
