Theodore O'Hara Sechrist (February 10, 1876 – April 2, 1950) was a professional baseball player. He was a pitcher who played for the New York Giants of the National League in one game, on April 28, 1899. He faced two batters and walked both of them. Because they did not score and he did not record an out, he has no official ERA from his appearance. In addition to his brief major league appearance, he played in the minor leagues from 1895 through 1904. He is buried in the Somerset City Cemetery, Somerset, Kentucky, with his wife, Gertrude.
