The only sports achievement more impressive than hitting 500 career Home Runs is crashing through the 600 homer barrier (as Willie Mays did in racking up 660) and moving on to the rarified air of the 700 plateau. Only three players have smashed the 700 home run mark - Barry Bonds (762), Hank Aaron (755) and Babe Ruth (714). Watch as Ken Griffey, Jr. (593) and Sammy Sosa (609), who was recently quoted as saying “If they let me, I will reach 700,” continue their quest to join the 700HRC.
