Rookie of the Year

Given to the top rookie-eligible players in both leagues, the Rookie of the Year Awards are voted voted upon by the Baseball Writers' Association of America prior to the beginning of the postseason and are based on a weighted points system. From 1947-48, it was given to the Majors' best overall rookie, but has been given to one player per league since 1949. On the 40th anniversary of the first award, the honor was named for Jackie Robinson, its first winner.
