About Sonny Siebert

Born 1937. Sonny Siebert is an American baseball player and basketball player.

Wilfred Charles "Sonny" Siebert (born January 14, 1937) is an American former Major League Baseball right-handed pitcher from 1964 to 1975. He finished with a record of 140-114 and a 3.21 ERA. He threw a no-hitter on June 10, 1966, against the Washington Senators. He was drafted simultaneously by the Cleveland Indians and the St. Louis Hawks of the NBA.

Early life Siebert was born on January 14, 1937, in St. Mary, Missouri. He attended Bayless Senior High School, and the University of Missouri. At Missouri, he played basketball for three years (1956-1958), leading the team in scoring his final year. He played baseball for one year, playing first base and leading the team in home runs (1958). He played on the 1958 team, along with future major league pitcher John O'Donoghue, that lost in the College World Series (CWS) finals in 12 innings to the University of Southern California (whose roster included, among others, future major league players Don Buford and Ron Fairly, and major league Hall of Fame executive Pat Gillick ). He was first-team All-Big 8 and third-team All-American. He was selected to the CWS All- Tournament Team that year. In 2017, he was inducted into the St. Louis Sports Hall of Fame. He was also drafted by the St. Louis Hawks of the National Basketball Association. Earlier in Siebert's life, his father told Siebert not to become a pitcher. His father had been a hard throwing pitcher as a young man and injured his arm preparing for a major league tryout, losing the opportunity to audition for Rogers Hornsby and the St. Louis Cardinals years earlier.

Major leagues

Cleveland Indians Siebert made his major league debut in 1964, pitching in 41 games for Cleveland, starting in 14 games. He had a 7–9 record with a 3.23 ERA. In 1965 and 1966 he had identical 16–8 win–loss records, with 2.43 and 2.80 ERAs respectively. Not long after conferring with pitching coach Early Wynn (himself a Hall of Fame pitcher ), on June 10, 1966, Siebert pitched a no-hitter against the Washington Senators. and "Sudden" Sam McDowell, who was considered to be the most talented pitcher in baseball (though not the winningest). In 1965, McDowell and Siebert ranked 1st and 3rd in ERA for the American League (Tiant was 25th); in 1966, Siebert and McDowell ranked 7th and 8th in ERA for the American League (their teammates Steve Hargan and Gary Bell being 3rd and 14th); and in 1967, Siebert and Tiant ranked 3rd and 10th.

Boston Red Sox Although ranking third in ERA for the second time in three years, Siebert's 1967 record was 10-12. In 1968, he had a 12–10 record. This was his final full year in Cleveland. Siebert spent all or part of five seasons with the Red Sox Siebert was the most recent American League pitcher to hit two home runs in one game, until July 27, 2023, when Shohei Ohtani matched him. Siebert accomplished the feat for the Red Sox on September 2, 1971, against the Baltimore Orioles, before the introduction of the designated hitter.

Final playing years He was traded in 1973 to the Texas Rangers, and then played for the St. Louis Cardinals, San Diego Padres, and Oakland Athletics. On September 11, 1974, he was credited with the win in a 25-inning Cardinal win over the New York Mets. It is the second longest game in innings played in National League history.

He was involved in a three-team deal on November 18, 1974, in which he was dealt along with Alan Foster and Rich Folkers from the Cardinals to the Padres for Ed Brinkman who had been sent to San Diego with Bob Strampe and Dick Sharon from the Detroit Tigers for Nate Colbert. Danny Breeden went from the Padres to the Cardinals to subsequently complete the transactions. He split the 1975 season, his final year as a player, between the Padres and the Oakland Athletics,
