Silver King, born Charles Frederick Koenig, was an American Major League Baseball player who had a significant impact on the sport during his career. He was a right-handed pitcher known for his exceptional speed and control, and his career spanned over a decade, during which he played for several teams.

King began his professional career with the St. Louis Maroons in 1886. He quickly established himself as a formidable player, and in 1887, he was transferred to the Chicago White Stockings, where he played for two seasons. During his time with the White Stockings, King achieved some of his most notable career highlights, including pitching a no-hitter against the Brooklyn Bridegrooms in 1888.

In 1889, King joined the St. Louis Browns and had an extraordinary season, winning 35 games and losing only 12. He led the league in shutouts and had an earned run average (ERA) of 2.69. His most remarkable achievement that year was pitching 55 consecutive scoreless innings, a record that stood for over a decade.

King's performance in the 1890 season was equally impressive. He won 30 games and had an ERA of 2.37. He also led the league in shutouts for the second consecutive year. Despite his individual success, the Browns struggled as a team, and King was traded to the Cincinnati Reds in 1891.

King's time with the Reds was less successful, and he was traded to the Pittsburgh Pirates in 1892. He spent two seasons with the Pirates before being traded to the New York Giants in 1893. King's performance declined during his time with the Giants, and he was released from the team in 1894.

King spent the final years of his career playing for minor league teams. He retired from professional baseball in 1897. Despite the decline in his performance towards the end of his career, King's achievements during his peak years were significant. He finished his career with a record of 203 wins and 152 losses, and an ERA of 3.18. He also had 50 shutouts and 1,054 strikeouts.

King's contributions to baseball were recognized posthumously when he was inducted into the Baseball Hall of Fame in 1967. His career remains a testament to his skill and dedication to the sport.
