Willie Lee McCovey (born January 10, 1938), nicknamed "Mac", "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.
One of the most intimidating power hitters of his era, McCovey was called "the scariest hitter in baseball" by pitcher Bob Gibson, an assessment with which Reggie Jackson concurred. McCovey's powerful swing generated 521 home runs, 231 of which he hit in Candlestick Park, the most hit there by any player, and included a home run of September 16, 1966 described as the longest ever hit in that stadium.
