Louis Criger (February 3, 1872 in Elkhart, Indiana – May 14, 1934 in Tucson, Arizona) was a Major League Baseball player for the Cleveland Spiders (1896-1898), St. Louis Cardinals (1899-1900), Boston Americans/Red Sox (1901-1908), St. Louis Browns (1909, 1912), and the New York Highlanders (1910). Criger became the first Opening Day catcher in Boston American League franchise's history. A catcher for most of Cy Young's 511 victories, he also caught every inning for eight games with Boston in the first-ever World Series in 1903, helping his team win the championship.
