With an absolutely loaded MLB rookie class this season, top 25 rookie rankings became a new monthly staple at Bleacher Report.
Now that the regular season has come to a close, it's time for one final version, this time with the list expanding from 25 to 50 players in an effort to illustrate what a truly remarkable group of newcomers there were across baseball.
Players are ranked based on their individual production, role with their team, and how they developed as the season progressed. In other words, a strong finish to the year carried more weight than a strong start that ended in steady regression.
