In 1884, Guy Hecker, who played for Louisville Colonels of the American Association, also earned the Triple Crown and is the only American Association pitcher to do so during their history. He had fifty-two wins, three-hundred eighty-five strikeouts and an earned run average of 1.80!
More than one-hundred twenty-five years of baseball, thousands of great pitchers, and the Triple Crown has only been earned thirty-five times by twenty-seven different Major League pitchers.
Grover Alexander (1915 & 1916), Lefty Grove (1930 & 1931), Sandy Koufax (1965 & 1966), and Roger Clemens (1997 & 1998) each accomplished the triple crown in consecutive years.
