I am shocked, shocked to learn that A-Rod was juiced when he played for the Texas Rangers. According to Sports Illustrated he was one of 104 major league baseball players (out of 1198) who were on steroids in 2003. Taking steroids was not banned by major league baseball until 2004. I wonder how much steroids improve a player's performance? Considering Barry Bonds, who was better as he approached 40 years old on steroids than he was at 27 when he wasn't on steroids, it appears that steroids do improve performance. Here is the SI article:
