Trout leads historical quartet

Keith Law's ranking of the best players in MLB under the age of 25 is exceptional for several reasons, but perhaps most notable is that none of the cream of the crop is anywhere close to the age limit. In fact, when you look at what Mike Trout, Bryce Harper, Giancarlo Stanton and Jason Heyward did in 2012 -- with Stanton and Heyward being the veterans, having played last season at age 22 -- it becomes clear that we just saw a season for the history books.

Much has been written about Trout and Harper, both of whom had all-time great seasons for their age bracket, but baseball has seen two phenomenal rookie hitters come up together before. Baseball has not, however, seen four players this young who were this good in the same season in nearly 50 years.
