Alex Rodriguez' home run production has tumbled since he hit 54 in 2007. He had 35 in 2008, 30 in 2009 and just 16 through 88 games this season. He could be headed for his lowest total since 1997, when he hit 23 in 141 games for Texas.
What does that mean for catching all-time leader Barry Bonds, who has 762? If A-Rod averages 30 a season--which might be asking a bit much as he gets older--it will take him at least five years to catch Bonds. A-Rod, who turns 35 next week, would be over 40.
Hank Aaron (755) averaged 28 homers after his 35th birthday, though he did hit 47 age age 37 and 40 when he was 39. Bonds stays out of this part of the discussion due to reports of him using performance enhancers.
