Who were the greatest rookie players in Boston Red Sox history? A few actually won the Rookie of the Year Award (ROY) and many others didn’t for the simple fact there was no award.
To determine who had that best introductory season, I’ll abide by the current rules that have fewer than 130 at-bats and for pitchers less than 50 innings. That reduces the competition by eliminating players such as Mookie Betts who put in half a season.
Certain positions have an abundance of players who deserve and a few positions are rather barren such as catcher.
