Sonny Siebert is born in St. Marys, Missouri.
Siebert signed with the Indians in 1958 and would go on to spend parts of six seasons in a Cleveland uniform and 12 total seasons in the Majors. He debuted in 1964 and would have back-to-back 16-8 seasons in his second and third years in the Bigs. The latter of the two would earn him his first of two All-Star appearances.
In addition to those two trips to the Midsummer Classic, Siebert also etched his name into the Indians history book on Friday, June 10, 1966, by throwing a 2-0 no-hitter against the Washington Senators. He allowed just two base runners in the contest – Dick Nen walked in the fifth inning and Paul Casanova reached on an error in the eighth inning by Chico Salmon. Siebert sat down seven Senators hitters in front of 10,469 fans at Cleveland Stadium while throwing the eleventh no-hitter in franchise history.
He spent parts of five seasons with the Boston Red Sox, nearly one full season in Texas with the Rangers, one season with the St. Louis Cardinals, and a split season in his final year in 1975 with the San Diego Padres and Oakland Athletics. He finished his career with a 140-114 record, a 3.21 ERA, 21 shutouts, and 16 saves.
