In 1931 rightfielder Earl Webb set the all time record with sixty-seven doubles during a single season; however, it was the only season in his career where he had more than thirty.
Joe Medwick hit forty (40+) or more doubles seven consecutive seasons and holds the National League single season record for doubles with sixty-four set in 1936.
In 1901, Roy Thomas played for Philadelphia in the National League. He holds the unique record for least doubles hit with at least five-hundred at-bats when he had only four. As if that were not amazing enough, he went on to tie his record in 1903.
