Joel Powers Sherman (November 4, 1890 – December 21, 1987) was a Major League Baseball pitcher for the 1915 Philadelphia Athletics.
The 1915 Athletics were one of the worst teams in major league history.
Sherman appeared in two games at the end of the season, completing his only start.
Sherman attended the University of Massachusetts Amherst, known at the time as "Massachusetts Agricultural College".
A Cape Cod native, he pitched for the Hyannis town team in the Cape Cod Baseball League for many seasons.
As a young man, he had played for the team from 1906 to 1913, prior to the formal organization of the Cape League in 1923.
Then after a 14-year hiatus he returned to play again for Hyannis in the newly-formed league from 1927 to 1931.
Sherman's long career with Hyannis, predating even the league itself, accounts for his being referred to by some as the "father of the [Cape] league."
