Alexander Nicholas Cosmidis (born September 22, 1928, at Fayetteville, North Carolina) is an American professional baseball scout. He was a minor league baseball infielder for eleven seasons, a manager for eight, and a scout since 1982.
Cosmidis grew up in Norfolk, Virginia, and went to school at Illinois Wesleyan University where he played baseball and joined Theta Chi. During this time, he was also on a semi pro team in Colerain, North Carolina. He was signed by the Chicago White Sox who assigned him to their farm team in Hot Springs, Arkansas where he earned co-MVP honors in the Cotton States League. His minor league playing career saw him in Waterloo, Iowa, Gastonia, North Carolina, and Nashville, Tennessee playing for the local nines. He spent three years with the team in Dallas and set a Texas League fielding record of sixty-six errorless games at second base. In 1957, he was awarded the Rawlings Silver Glove trophy for best minor league second baseman. He spent a campaign with Portland in the Pacific Coast League and one with Rochester in the International League at the Triple-A level but never made it to the big leagues as a player.
