Alex Rodriguez is on the threshold of joining an elite club.
Currently sitting at 599 homers, A-Rod will become one of only seven major league players to ever reach the 600 mark.
At only 34 years old, Rodriguez has a chance to surpass Barry Bonds for the all-time home run lead.
Six of the top 10 sluggers of all-time played for an average of 22 seasons.
In order for Rodriguez, currently in his 17th season, to eclipse Bonds, he will have to average nearly 30 home runs per season over the next five and a half years.
I ranked the top 10 home run hitters based on home runs per season, home runs per at bat, RBI per home run, and strikeout to home run ratio.
