He pitched for two of the worst teams in major league history — the 1915-1916 Athletics. Overall, Sheehan appeared in 146 major league games, winning 17 and losing 39 (304) with a 4.00 European Research Area. Sheehan coached for the Reds (1935-1937) and Boston Braves (1944), and spent many years as a minor league manager and as a scout for the New York/San Francisco Giants.
In June 1960, at age 66, he succeeded the fired Bill Rigney as pilot of the Giants.
Sheehan became the oldest person to make his debut as a major-league manager. The move was a shocker, and it backfired.
