Ferris Fain was plucked in the Rule 5 Draft after the 1946 Season, and he was inserted as the starting First Baseman the year after.  Fain immediately showed extraordinary plate discipline as he had a ,414 OBP as a rookie.  Fain played his first six seasons in the Majors with the Philadelphia Athletics, and he never had an OBP less than .412, and he was always in the top seven in that category.  Fain would be named an All-Star in 1950, and would be again in 1951 and 1952, with the latter year seeing him win the OBP Title with .438.

For the first four seasons of his Major League career, Jack Coombs was an average Pitcher at best and did not have any remarkable moments.  He was 35-35, and in 1910, his season started so poorly that he was demoted to the bullpen.  The legend has it that he rediscovered his overhand curve, and he went on a tear that had no equal in Athletics history.

An honored member of the three straight World Series Championships in the first half of the 1970s, Joe Rudi, was not just there, as the prime of his career occurred during this Oakland dynasty.

After a breakout season with the Chicago Orphans in 1901 where he batted .335 with 187 Hits, Tully “Topsy” Hartsel, bolted from the National League to the American League and Connie Mack’s Philadelphia Athletics.
