The Root Cause of the M’s Poor 2007 DER (Part 4)
Cause of Bad DER of 2007 M’s (Part 3) which I wrote February 20,2008 should has been the last part of the series.
But there was a drastic change in defense of M's.
Paul Covert -san calculated the DER in 2008 by manager:
Defensive Efficiency (calculated as [H-HR+ROE]/[BFP-K-BB-HBP-HR]):
McLaren April .690
McLaren May .665
McLaren June .667
(McLaren overall .675)
Riggleman June/July .720
A drastic change.
