Ordinary MLB prospects and journeymen blossom into breakout stars every season, and (nearly) every team in 2013 has kept one for itself.
Bleacher Report's Rick Weiner distinguishes these players from the regular population by the way they have been "elevating their games to levels we've not seen before—and increasing the expectations that we have of them going forward." A simple yet satisfactory definition for our purposes.
Prior to this summer, names like Chris Johnson, Yasiel Puig, Matt Harvey and Matt Carpenter were recognized, but certainly not revered. After all, we had never seen them sustain excellence at the major league level.
My, how things have changed.
In several cases where a true breakout hasn't happened, we'll praise midseason call-ups who have contributed immediately.
