Willie McCovey broke into the big leagues and made an immediate impact. Voted the NL’s Rookie of the Year in 1959, he was an All Star by ’63. That season his 44 homers led the Senior Circuit.
As pitchers dominated the 1960s, McCovey hit exactly 300 homers in the decade. In the Year of the Pitcher in 1968, he put up league-leading numbers in homers (36), RBI (105), slugging percentage (.545), and OPS (923). Stretch was even better in ’69 when earned the Most Valuable Player Award. The big first baseman hit .320 with career bests in homers with 45 and RBI with 126. Opposing pitchers intentionally walked McCovey an NL high 45 times. His OPS+ was an astounding 209.
Though his production declined as the next decade progressed, he still averaged more than 20 homers per season in the 1970s. When he retired after the 1980 campaign McCovey had 521 homers and 1,555 RBI.
