A graduate of the
University of Illinois, he was a member of the Kappa Kappa chapter of
Sigma Chi. , Stahl,
Bill Carrigan and
Michael T. McGreevy during spring training in 1912. Stahl began his baseball career as a
catcher with the Boston Americans in 1903, before being purchased by the Washington Senators, where he moved to first base full-time, with occasional stints in the outfield. He was purchased from the Senators by the Chicago White Sox in May 1907, although he did not play that year. In October, the White Sox traded him to the New York Highlanders in a three-team trade, with
Frank LaPorte going from the Highlanders to the Americans and
Freddy Parent going from the Americans to the White Sox. In July 1908, he was purchased from the Highlanders by the Boston Red Sox. He was regarded as a good fielder and an average hitter, although he did lead all hitters in the
American League in
home runs with 10 in . He also
struck out 128 times for the year, a record that would stand until 1938. As a player-manager, he led the Senators to two seventh-place finishes in 1905 and 1906. Stahl sat out the 1911 season, instead opting to return to his native Illinois, where he took a position as a bank manager for a firm on the South side of Chicago. Stahl was offered a position as player-manager of the
Boston Red Sox for 1912 — a position which required the team and Stahl to obtain formal reinstatement by baseball's
National Commission since Stahl had been previously deemed to be in violation of "rule 33" when he failed to report in 1911. Stahl has a measure of immortality as the acknowledged
eponym of the term "jaking it", a baseball phrase for faking an injury to stay out of the lineup, or otherwise loafing. Stahl was not related to Red Sox teammate
Chick Stahl, despite contemporary accounts erroneously listing them as brothers. ==Managerial record==
