Home run milestones and 3,000th hit

During his days in Atlanta, Aaron reached several milestones; he was only the eighth player ever to hit 500 career home runs, with his 500th coming against Mike McCormick of the San Francisco Giants on July 14, 1968—exactly one year after former Milwaukee Braves teammate Eddie Mathews had hit his 500th. Aaron was, at the time, the second-youngest player to reach the milestone. On July 31, 1969, Aaron hit his 537th home run, passing Mickey Mantle 's total; this moved Aaron into third place on the career home run list, after Willie Mays and Babe Ruth. At the end of the 1969 season, Aaron again finished third in the MVP voting.

In 1970, Aaron reached two more career milestones. On May 17, Aaron collected his 3,000th hit, in a game against the Cincinnati Reds, the team against which he played in his first major-league game. Aaron established the record for most seasons with thirty or more home runs in the National League. On April 27, 1971, Aaron hit his 600th career home run, the third major league player ever to do so. On July 13, Aaron hit a home run in the All-Star Game (played at Detroit's Tiger Stadium) for the first time. He hit his 40th home run of the season against the Giants ' Jerry Johnson on August 10, which established a National League record for most seasons with 40 or more home runs (seven). At age 37, he hit a career-high 47 home runs during the season (along with a career-high.669 slugging percentage) and finished third in MVP voting for the sixth time. During the strike-shortened season of 1972, Aaron tied and then surpassed Willie Mays for second place on the career home run list. Aaron also drove in the 2,000th run of his career and hit a home run in the first All-Star game played in Atlanta. As the year came to a close, Aaron broke Stan Musial 's major-league record for total bases (6,134). He finished the season with 673 career home runs.
