We've all read about how A-Rod's now the favorite to get Barry's career HR record. But in addition to the fact that he'll have to age as "well" as Barry did, I just looked up this interesting fact:
Over the last three seasons, A-Rod got 27 intentional walks. From 2002-2004 Barry got 249. I still think A-Rod can't get the career HR title without some serious longevity, durability, and more cooperation from the opposing pitchers than Barry got.
