The K-Rod comment was focused on the perception of his performance, and how it might have been different had the Mets been in the race.<br /><br />I don't like OPS, though; I prefer a metric with similar inputs like Component ERA or the "eRA" I publish here. Rodriguez' eRA rose from 3.50 in 2008 to 3.93 this year, and while that is above average, it's not particularly impressive either.phttps://www.blogger.com/profile/18057215403741682609noreply@blogger.comtag:blogger.com,1999:blog-12133335.post-21503974220394119232009-11-19T14:21:22.202-05:002009-11-19T14:21:22.202-05:00Using RA as a measure for Frankie Rodriguez is mis...Using RA as a measure for Frankie Rodriguez is misleading -- his RA is exaggerated by a few big run-scoring games. For closers, I prefer OPS against as a fairer measure of overall performance. By that measure, Frankie's '09 was not far off of his '08 performance with the Angels, and was far better than the NL average for pitchers generally and for relievers in particular.birtelcomhttps://www.blogger.com/profile/03605568568550841634noreply@blogger.com
