Giles was a superb Negro League first baseman and a lifetime .300 hitter. Black all-star
Ted "Double Duty" Radcliffe called Giles "the best colored first baseman I ever saw..."
Giles played for the St. Louis Stars, one of the Negro Leagues' greatest teams, from
1929 through 1931. In a 1930 eight-game series against major league all-stars, the
Stars won six games against the pitching of Willis Hudlin
, George Uhle, and Earl
Whitehill. The Stars won the Negro National League
pennant in 1930 and 1931. In the
twilight of his career, Giles played for the Satchel Paige
All-Stars. His final contribution
to pro baseball was as manager of the 1935 Brooklyn Eagles.
