Silver King (January 11, 1868 – May 21, 1938), born Charles Frederick Koenig, was an American Major League Baseball player from 1886 through 1897.

Newspapers in St. Louis, Missouri, gave him the nickname Silver King, referring to his prematurely gray hair and shortening his German surname.

[1] A native of St. Louis, Koenig broke into baseball at age 18, playing for St. Joseph in the Western League.

His strong fastball enabled him to become a notable strikeout artist; he finished among the league's top 10 in that category six times.

(King lost 1–0, and pitched only eight innings in the loss, so this game is not officially recognized by MLB as a no-hitter.)
