I hate to give you he said, she said story, but here it is.
A friend of mine is a sports reporter in Dallas. I am not sure how, but he knows the trainer with the Astros. He said Clemens has been using for a while. He wanted to run with the story, but the trainer said, it would be obvious he talked and his career would be over.
I generally don't give things like this much credit, but he is not a liar from all the years I have known him. Always has been a straight shooter.
Heard a story in a similar fashion about Biggio. Who woulda thunk it???
