Who was lucky and who wasn't in 2011? EPR – Expected Pitching Record:The Expected Pitching Record or "EPR" method was first developed prior to the 1993 season in preparation for a possible Jaime Navarro arbitration case. Navarro had posted a 17-11 record in 1992 with an ERA of 3.33, despite having a poor walk/strikeout ratio. The EPR method was developed to demonstrate that Navarro's good pitching record was based in large part on extreme good luck and that with normal luck Navarro's record would be much worse. The following year, luck did even out for Navarro and he posted an 11-12 record with an 5.33 ERA. |
