Hall went from Columbus to the St. Paul Saints for part of the 1909 season, then on to the Red Sox in June of that year.

[2] Hall pitched both in relief and as a starter for the Red Sox from 1909 through 1913, winning the first game played in the new Fenway Park in 1912, before being released at the end of the 1913 season.

His performance during the 1920 season, in which he accumulated a 27-8 record with a 2.06 ERA, helped lead the Saints to first place in the American Association.

He moved on to the Sacramento Solons of the PCL in 1924, then, after a brief stint with the Birmingham Barons, ended his baseball career in 1925 at age 41 with the Minneapolis Millers.
