Turk Wendell had an 11 year big league career with a career era+ of 109.  He had a horrible stint in '01, but bounced back nicely in '03 with an era+ of 118 in 53 games for the Phils.  Roberto Hernandez is still enjoying a great career, pitching in 17 seasons with a career era+ of 131.  In '04 with the Phils he provided slightly below league average statistics, culminating in an era+ of 94.  In my opinion, I would love to have these type of pitchers for my middle relief crew.  Now, lets compare these pitchers with Durbin, Rosario and Bisenius.  Durbin (I am assuming J.D.?) has appeared in 23 games spread across parts of two seasons.  He is entering his age 26 season with a career era+ of 75.  Rosario, 27, has appeared in 40 games, also across two seasons, and has a career era+ of 76.  Bisenius, while I think will never be more than a 12th man, at least has "potential", albeit a very little amount of potential.  His era's have steadily rose as he progressed through the minor league levels, culminating in a 5.48 era in AAA last year.  Now 25, this year is really the last chance Bisenius has to turn his career into something meaningful.   I hate to say it, but pitchers rarely find "command" and "control" when they are 25, 26, and  27.  Generally, pitchers at these ages are what they are.  In the case of Durbin, Rosario, and Bisenius, these pitchers are not good.
