Getting Typecast: Neftali Feliz

After a back and forth spring, it was announced today that Neftali Feliz would be returning to the back end of the bullpen as the Ranger's closer. I don't need to state or explain why a starter is more valuable than a closer. That horse has been beaten to death. As for Feliz.. He was excellent as a starter during his limited minor league career, and has been just as good as a reliever since reaching the show in late 2009.  I am unaware of any scout or talent evaluator who doesn't think he can succeed at the top of a rotation at this point in his career.

Regardless, he is closing, and so what does this mean for a player with his track record?
