Jockbeat: A-Rod's Juice Didn't Buy Him Much
We did some checking on our own.
The Seattle parks were among the league's toughest when A-Rod was there. As we all know, in 2001 he moved to the Rangers, where he played his home games in The Ballpark at Arlington. From 2001-2003 he hit 156 home runs, 31 more than during his three years with the Mariners. As this was the period during which he admitted to taking Primobolan and testosterone, this looks very much as of he did get some sort of artificial boost. The problem is that over the same period he hit 70 home runs on the road - actually four fewer than his road record with Seattle.
It may be no coincidence that over those three years the Rangers ballpark was one of the best hitters parks in the game. If steroids were inflating A-Rod's record over those three reasons, why were they only inflating them when he was playing at home? It could and probably will be argued that he might have been juicing while playing for Seattle, but if so why did the effects of the juice not show up with he was playing at home?
Rodriguez did get a bump while playing for the Rangers, but it very much appears as if it was from his home ballpark. It may or may not be relevant that in the five years he has played for the Yankee he has slightly better at home - 110 home runs at Yankee Stadium, 98 around the rest of the league.
