Playing at First Base, Davis would go on the best run of his career. While this was the dead ball era, he would lead the AL in Home Runs four years in a row (1904-07) and won two RBI Titles in 1905 and 1906. Davis had three .300 seasons, though he didn't have the best On Base Percentage (.337). Late in his career, he would help the Athletics win the World Series in 1910 and 1911.
Davis would return through the 1913 season as a player and coach, but by this point, he was hardly a player. From his return to when he hung up the cleats for good in 1917, he only played in 19 Games but was a member of the 1913 World Series Championship.He would overall record an even 1,500 Hits for Philadelphia with 761 Runs Batted In.
