About Fred Merkle
Carl Frederick Rudolf Merkle (also sometimes documented as Frederick Charles Merkle; December 20, 1888 – March 2, 1956), nicknamed "Bonehead", was an American first baseman in Major League Baseball from 1907 to 1926. Although he had a lengthy career, he is best remembered for a controversial base-running mistake he made as a rookie while still a teenager. Merkle played his first Major League game at the age of 18, with the New York Giants in 1907. Merkle became the Giants' regular first baseman by 1910 and contributed in that role to three straight pennant winners from 1911 to 1913. In April 1917, the Robins sold Merkle to the Chicago Cubs, the team against which he had made his infamous play in 1908, with whom he continued as the regular first baseman through 1920.
