Ronald Richard Schueler (born April 18, 1948, in Catharine, Kansas) is a former Major League pitcher, pitching coach, general manager and scout. Schueler was called up at the start of the 1972 season, twenty-three years old. On April 16, 1972, two days before his twenty-fourth birthday, Schueler made his major league debut as a reliever in a game against the San Diego Padres at San Diego Stadium. He pitched two innings and only gave up one hit in that game, but despite his efforts, the Braves lost. Schueler went on to start thirty-eight games over two years with the Braves. After the 1973 season ended, Schueler was dealt to the Philadelphia Phillies for infielder Craig Robinson and pitcher Barry Lersch.
After a mediocre season as a starter, the Phillies converted Schueler to a relief pitcher. He pitched two more seasons in Philadelphia as a reliever and spot starter.
Schueler ended his active career to become pitching coach of the White Sox in the middle of the 1979 season, after the illness and death of Fred Martin. He remained with the ChiSox through the 1981 season. In 1982, Schueler was hired by the Oakland Athletics to be their pitching coach. Schueler worked for three seasons in Oakland. Schueler joined the Pittsburgh Pirates in 1986 after a year out of the majors.
