Aaron is also in the top five for career hits (3,771) and runs (2,174). He is one of only four players to have at least seventeen seasons with 150 or more hits. Aaron is in second place in home runs (755) and at-bats (12,364), and in third place in games played (3,298). At the time of his retirement, Aaron held most of the game's key career power hitting records.
All Aaron's home runs have been struck for the Braves, albeit some for the Milwaukee Braves and others for the Atlanta Braves. Ruth hit his first 49 for Boston's Red Sox, his next 659 for the Yankees, his last six for the Boston Braves of the NL. Both were 40 years old when they did it. Ruth, however, quit the Braves a week after hitting 714, in a dispute with the club over his status as playing-veep.
