BATTERS: BA/xBA under- and over-performers

Over the past six weeks or so, the Batter Buyers Guide has focused on identifying value in various areas using BPIs. With one-third of the season in the books, it seems like a good time to dig deeper into BA results. We will do so by isolating extreme positive and negative BA/xBA discrepancies in an effort to identify which players are under-performing, and which are over-performing.

We begin with the list of BA under-performers, through the games of 6/7:

Name                 AB    BA   xBA   Diff   h%
==================  ===  ====  ====  =====  ===                                   
Hechavarria,Adeiny  161  .186  .254  -.068  21%
Young,Chris         147  .177  .239  -.062  20%
