In 1999 his games played began tailing off. He had only been inured once before that. Bonds began taking steroids in 99. That's more than a bit disingenuous on several levels. First, Bonds turned 34 that year. Aging is highly correlated with injuries. Second, he played an average of 2 fewer games per season from 2000-2004 than he did from 1995-1998. (and I'm not sure you understand what I was saying, because you just restated the correlation) I am sure that there were times when steroids extended his career, and other times when it took some ABs away from him in a season. Barry played about the same number of games late in his career as he did earlier in his career, but he ABs went down significantly. He was used as a PH the times he didn't start. Bonds: "It makes me grow faster, but if you're not careful, you can blow it out." He did just that to his elbow in 99.
