There are only two Major League Baseball (MLB) players who have hit 700 or more home runs in their careers: Babe Ruth and Hank Aaron.
Babe Ruth is widely considered to be one of the greatest baseball players of all time, and his 714 career home runs were a record that stood for many years. Ruth played for the Boston Red Sox, New York Yankees, and Boston Braves during his career, which spanned from 1914 to 1935. He was known for his powerful swing and his ability to hit home runs, which was a relatively rare feat in the early days of baseball. Ruth was a 12-time American League home run champion and led the league in slugging percentage 13 times. He was also a seven-time World Series champion and a two-time All-Star. Ruth was inducted into the Baseball Hall of Fame in 1936, just one year after his retirement.
Hank Aaron is another legendary baseball player who hit 700 or more home runs in his career. Aaron played for the Milwaukee and Atlanta Braves, as well as the Milwaukee Brewers, during his career, which spanned from 1954 to 1976. Aaron’s 755 career home runs were a record until Barry Bonds broke the record in 2007. Aaron was known for his consistent hitting and his ability to hit home runs in clutch situations. He was a 25-time All-Star, a three-time Gold Glove winner, and a one-time National League MVP. Aaron also won a World Series championship with the Braves in 1957. He was inducted into the Baseball Hall of Fame in 1982.
While there have been many great baseball players throughout history, only these two players have hit 700 or more home runs in their careers. This is a testament to the rarity and difficulty of achieving this feat in the game of baseball.
In summary, as of my knowledge cutoff of September 2021, only one player has hit 700 home runs in their MLB career: Barry Bonds. While there have been a handful of other players to hit 600 or more home runs, hitting 700 is an incredibly rare feat that requires a combination of incredible talent, longevity, and consistency over many years.
