Amphetamines, better known in the post-Ball Four baseball world as greenies, are uppers. Many players in the 60s and 70s took them as a performance-enhancing drug. The following is a transcript of a Playboy interview found in James Reston Jr.'s Collision at Home Plate:
"But would you use them for anything other than dieting" [Rose] was asked.
"There might be some day when you played a doubleheader the night before, and you go to the ballpark for a Sunday game, and you just want to take a diet pill, just to mentally think you are up. You won't be up, but mentally you might think you are up."
"Does it help your game?"
"It won't help your game, but it will help you mentally. When you help yourself mentally, it might help your game."
"You keep saying you might take a greenie. Would you? Have you?"
"Yeah, I'd do it. I've done it."
They way I decipher Rose's double-talk is that he didn't believe that greenies would help the physical part of the game, but would help the mental aspect. In any case, he believed that they worked, observe the next paragraph from Reston:
He did not say, however, that he was doing it nearly every day, and that he was teaching younger players how to do it. But when federal narcotics agents came calling at Veteran Stadium, that was the understanding of [GM] Bill Giles.
The trial of Mazza eventually blew over. He was found innocent in court. However, one of his statements was that "[The prescriptions] were made at the request of the ball players and were done in good faith. Pete Rose was having trouble with his weight and he needed some help with his thirty-eight year old body." So without a doubt, Pete had a bottle of greenies in his medicine cabinet. He admitted in Playboy to prior use. It was the belief of people in the Phillies organization that he wasn't just using, he was also getting younger players involved.
So Charlie Hustle spent at least some of his career with some extra hustle coming out of a bottle. It's not too hard to believe that steroids are to power hitters what greenies are to single hitters. The evidence we have against Rose is much strong than that against Bonds. Yet somehow there isn't a huge asterisk next to 4256 in the books. It doesn't have the same taint that is being attached to Barry's accomplishments. If we discount baseball records due to chemistry, one of the first we have to roll back is Rose's.
