Take BABIP for example... because of how BABIP is used it's biased towards power hitters, because if 2 players hit for exactly the same average but one hits 30 HRs and one hits 2, the guy with 30 will have a more sustainable BABIP because he had 28 more hits removed from the equation so his average is lower. Not sure I would necessarily say bias. The more true outcomes(K/BB/HR) a player has the less his stats are going to be impacted by a change in BABIP. Most players should fall within a certain range of BABIP. I would guess in the .280-.350 range. Gamel, Salome, and Escobr all had really high BABIP's last year. Probably not sustainable for any of them. Salome and Gamel put up around .800 OPS with a normalish BABIP(because there really isn't a "normal" BABIP) in previous years where Escobar was only around .700 OPS with a normalish BABIP. I think that Escobar will carry a higher BABIP through his career than either Salome or Gmel because he has speed so his BABIP won't drop as far. Edit: Forgot to add that players will usually stay within a certain range of BABIP. If Fielder for instance would have a BABIP in the .330 rang one year, we would expect him to have a drop off the next year since he is usually in the .290-.300 range. Gamel and Salome haven't been really picked apart as much because they really didn't have as much of a chance to make the MLB club this year. Not that Escobar does, but trading Hardy to get a pitcher seemed somewhat plausible where trading the players in from of Gamel or Salome didn't. I am sure you would have seen the same things about Gamel or Salome's seasons in 2008. Of course they had around .800 OPS in previous seasons so they both had decent season's before. Of course they would have had their defense picked apart. Then add to that, both are playing behind somewhat average or below average players in some aspect of the game where Escobar is playing behind our best al around player. Next year when the talk switches to Weeks vs. Escobar will be even more interesting. If Weeks plays around average defense while putting up a .370+ OBP and Escobar repeats his 2008 season in AAA, then I think the organization has a really tough choice. If Weeks has bad defense or another OBP in the .340 range, I think Escobar is the starting 2B for a season until Green or Lawrie get the call up.
