Francis Joseph "Lefty" O'Doul (March 4, 1897 – December 7, 1969) was an American professional baseball player and manager.

His final duty station was Mare Island, and according to his obituary in the San Francisco Examiner, he separated from the Navy as a Seaman First Class (E-3).

After developing a sore arm which forced him to give up pitching, he returned to the Pacific Coast League and transitioned into becoming a power-hitting outfielder.

O'Doul began his professional career as a left-handed pitcher with the minor-league San Francisco Seals of the Triple-A Pacific Coast League.

In 1927, he became the second of only four Pacific Coast League hitters to have hit 30 home runs and stolen 30 bases in a season (with the other three being Tony Lazzeri (1925), Frank Demaree (1934), and Joc Pederson (2014)).

His hit total broke the previous National League record of 250 by Rogers Hornsby of the 1922 St. Louis Cardinals.

One of his outstanding accomplishments while managing the Seals was developing the young Joe DiMaggio, who went on to a Hall of Fame career with the New York Yankees.

"[7] In addition to the Seals, O'Doul also managed the San Diego Padres (1952–1954), the Oakland Oaks, the Vancouver Mounties (1956), and the Seattle Rainiers (1957).

[8] O'Doul was instrumental in spreading baseball's popularity in Japan, serving as the sport's goodwill ambassador before and after World War II.

The popular hofbrau-style restaurant and bar he founded in 1958 operated for years after his death as Lefty O'Doul's Restaurant and Cocktail Lounge[10] on Geary Street, still serving his original recipe for Bloody Mary[11] (although one news account says it was modified in the 1960s by O'Doul's bartender Chuck Davis).

[16] Besides the ineligible Shoeless Joe Jackson, O'Doul has the highest career batting average of any player eligible for the National Baseball Hall of Fame who is not enshrined.

[17] On November 5, 2021, he was selected to the final ballot for the Baseball Hall of Fame's Early Days Committee for consideration in the Class of 2022.
