context_page_description: In Major League Baseball, the Rookie of the Year Award is given annually to two outstanding rookie players, one each for the American League and National League, as voted on by the Baseball Writers' Association of America. The award was established in 1940 by the Chicago chapter of the BBWAA, which selected an annual winner from 1940 through 1946. The award became national in 1947; Jackie Robinson, the Brooklyn Dodgers' second baseman, won the inaugural award. One award was presented for all of MLB in 1947 and 1948; since 1949, the honor has been given to one player each in the NL and AL. Originally, the award was known as the J. Louis Comiskey Memorial Award, named after the Chicago White Sox owner of the 1930s. The award was renamed the Jackie Robinson Award in July 1987, 40 years after Robinson broke the baseball color line.
  Of the 140 players named Rookie of the Year, 16 have been elected to the National Baseball Hall of Fame—Robinson, five AL players, and ten others from the NL. The award has been shared twice: once by Butch Metzger and Pat Zachry of the NL in 1976; and once by John Castino and Alfredo Griffin of the AL in 1979.

  Of the 140 players named Rookie of the Year (as of 2016), 16 have been elected to the National Baseball Hall of Fame—Robinson, five AL players, and ten others from the NL. The award has been shared twice: once by Butch Metzger and Pat Zachry of the NL in 1976; and once by John Castino and Alfredo Griffin of the AL in 1979. Members of the Brooklyn and Los Angeles Dodgers have won the most awards of any franchise (with 18), twice the total of the New York Yankees, and members of the Philadelphia and Oakland Athletics (eight), who have produced the most in the AL. Fred Lynn and Ichiro Suzuki are the only two players who have been named Rookie of the Year and Most Valuable Player in the same year, and Fernando Valenzuela is the only player to have won Rookie of the Year and the Cy Young Award in the same year. Sam Jethroe is the oldest player to have won the award, at age 32, 33 days older than 2000 winner Kazuhiro Sasaki (also 32). Yordan Álvarez of the Houston Astros and Pete Alonso of the New York Mets are the most recent winners.
