Willie Lee McCovey (born January 10, 1938 in Mobile, Alabama), nicknamed "Big Mac" and "Stretch", is a former Major League Baseball first baseman. He played nineteen seasons for the San Francisco Giants, and three more for the San Diego Padres and Oakland Athletics, between 1959 and 1980. He batted and threw left-handed and was inducted into the Baseball Hall of Fame in 1986.
Prior to playing for the San Francisco Giants, McCovey played for a Giants' farm club in Dallas, Texas that was part of the Class AA Southern League. In that league, he did not participate when his team played in Shreveport, Louisiana due to segregation in that city. He later played for the Pacific Coast League Phoenix Giants just prior to joining the San Francisco Giants.
In his Major League debut on July 30, 1959, McCovey went four-for-four against, hitting two triples and two singles against Hall-of-Famer Robin Roberts en route to a .354 batting average that year, in which he won National League Rookie of the Year honors while playing in just 52 games.
