Reginald Martinez "Reggie" Jackson (born May 18, 1946) was a professional American baseball player from 1967 to 1987. His father Reginald Martinez was a Puerto Rican who played for the Negro Leagues. He was inducted into the United States Baseball Hall of Fame in 1993 in recognition of his talents. He was born in Wyncote, Pennsylvania.
Jackson's nickname was "Mr. October" due to his outstanding overall performances in the five World Series that he appeared in. In 27 World Series games, he amassed 10 home runs, including four in a row (three of them on consecutive pitches), 24 RBI and a .357 batting average.
Jackson's other accomplishments include winning the 1973 regular-season MVP award, amassing a total of 563 career homeruns, maintaining a .490 career slugging percentage, and the dubious distinction of being the all-time leader in striking out with 2597. Jackson played with the Kansas City and Oakland Athletics, Baltimore Orioles, New York Yankees, and, in the twilight of his career, the California Angels.
The now-discontinued "Reggie Bar" candy bar was named after the ballplayer.
His jersey number, 44, was retired by the Yankees in 1993. In 2004, the A's retired the number 9 that he wore during his days in Oakland. He is the only non-pitcher to win World Series most valuable player honors twice (in 1973 with the Oakland A's and in 1977 with the New York Yankees).
