Consider the question. Of the 140 players named Rookie of the Year (as of 2016), 16 have been elected to the National Baseball Hall of Fame -- Jackie Robinson, five American League players, and ten others from the National League. The award has been shared twice: once by Butch Metzger and Pat Zachry of the National League in 1976; and once by John Castino and Alfredo Griffin of the American League in 1979. Members of the Brooklyn and Los Angeles Dodgers have won the most awards of any franchise (with 17), twice the total of the New York Yankees, and members of the Philadelphia and Oakland Athletics (eight), who have produced the most in the American League. 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). Michael Fulmer of the Detroit Tigers and Corey Seager of the Los Angeles Dodgers are the most recent winners.
