Joseph Carl Oeschger (May 24, 1892 – July 28, 1986) was an American pitcher in Major League Baseball. He played for the Philadelphia Phillies, New York Giants, Boston Braves, and Brooklyn Robins from 1914 to 1925. Oeschger is best known for holding the MLB record for the most innings pitched in a single game. In 1920, both Oeschger and Leon Cadore pitched 26 innings for their respective teams in a game that was eventually called a tie due to darkness. After his baseball career ended, Oeschger was a teacher for the San Francisco Board of Education for 27 years.
