John Joseph Martina (July 8, 1889 – March 22, 1962), known as Oyster Joe, was an American professional baseball player. A right-handed pitcher and a native and lifelong resident of New Orleans, Louisiana, he spent 22 seasons in baseball, but only one year—1924—in the Major Leagues as a member of the world champion Washington Senators. He won 349 minor league games, with 277 defeats charged against him.[1]

The 6 ft (1.8 m), 183 lb (83 kg) Martina began his career at age 20 in 1910 and by the time he hung up his spikes in 1931, he had won 20 games seven times, including a 28-win season in 1919 for the Beaumont Oilers of the Texas League. He was 34 years old when, after consecutive 20-win campaigns for his hometown New Orleans Pelicans of the Southern Association, he made the 1924 Senators' team. In Martina's only big-league season, he worked in 24 games, including 14 starts. He won six games and lost eight, posting eight complete games with no shutouts. In 1251⁄3 innings pitched he allowed 129 hits and 56 bases on balls, with 57 strikeouts. He compiled a mediocre 4.67 earned run average, well above the staff ERA (3.34).
