By the time the season’s final month arrives, most MLB teams have little room for a September addition to push his way into a significant role.

However, there are always at least a few players among the wave of September call-ups who make a splash, whether it’s a young player getting an extended look for a non-contender or a veteran serving as a needed upgrade on a playoff hopeful.
