On today's list of the No. 26-50 players in baseball according to the ESPN 500, Miami Marlins ace Josh Johnson came in at No. 30, one spot behind fellow sometimes-injured starter Chris Carpenter. It's easy to see why Johnson (and Carpenter, for that matter) ranked so highly, as they are dominating starters when they take the mound.
Johnson's career ERA- is 70, meaning he has prevented runs at a rate 30 percent better than an average pitcher in that time. To put that in perspective, Roy Halladay's career ERA- is 71. On a per-inning basis, Johnson stacks up favorably against any pitcher in the game.
