Jockbeat: A-Rod’s Juice Didn’t Buy Him Much


In the middle of this storm of anti-Rodriguez hype, a calm voice from sabermetrician J.C. Bradbury presents the case that the two steroids A-Rod took most likely had no impact on his performance: “It’s probably best to say that there was no observed effect. It is possible that the steroids did give Rodriguez a boost, and this may have helped him through an injury or some other factor that my estimate does not account for. It’s also likely that he had more home runs than expected through random chance.” Check out Bradbury’s reasoned argument at

We did some checking on our own.

From 1998-2000, while with the Seattle Mariners, A-Rod played about
half his games at the Kingdome and then at Safeco Field. Over those
three seasons, he hit 125 home runs, just 51 at home and 74 on the
road. As any decent baseball analyst knows, it’s road performance on
which a hitter’s real reputation should be based – a home park might
distort one’s stats, but averaged out over all other league ballparks
you get a more accurate assessment of a slugger’s real ability.

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

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.
