At the end of April, I used Jeff Zimmerman’s updated xBABIP spreadsheet to determine which players’ BABIPs exceeded their xBABIPs by the greatest amount. Of the five players listed in the initial look, all of them did indeed experience a decline in BABIP, nearly all being a significant falloff. Of course, four of the five were sporting .400+ BABIP marks, so of course even without a formula, you would assume regression was coming. We now sit a bit further along than the exact mid-season mark, so BABIPs are much more reasonable at this point. These are the 10 hitters whose BABIP marks exceed their xBABIP marks by the greatest degree.
