Jason Isringhausen knew something was wrong immediately after he threw what might be his last pitch. Results of an MRI confirmed the worst today as his right elbow "strain" became a torn UCL. He will undergo Tommy John surgery. It is not known when he will have the surgery, but his 2009 season is over. If he attempts another comeback, 2010 would also be questionable.
If it is the end of the road for Jason Isringhausen he will finish as a two time all-star. After starting his career as a starting pitcher for the Mets, The former member of "Generation K", found a niche as a closer for the Oakland A's. However, he really made a name for himself as a member of the St. Louis Cardinals. His best stretch came in a Cards uniform from 2002-2005. Over the four year period he averaged an ERA/FIP of 2.65/2.46 and 35 saves. He currently owns a career record of 45-50 with a ERA/FIP of 3.60/3.88 and 293 saves.
Best of luck Izzy.
