Willie Lee McCovey (January 10, 1938 – October 31, 2018), nicknamed "Mac," "Big Mac," and "Stretch," was an American professional baseball first baseman. He played for the San Francisco Giants of Major League Baseball for 19 seasons, and three more in MLB 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. He was known for being a pull hitter, causing some teams to employ a shift to defend in critical situations.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 on September 16, 1966, described as the longest ever hit in that stadium.
He is also known as Willie Lee McCovey.
