The lifelong baseball fan used the film to perfect his own game and took steroids to get to grips with his pitching skills.
He tells Playboy magazine: "I wanted to put a little zip on my fastball. I didn't want to look like I was lily-arming it up there. I was always a hit-the-spots, low-zone pitcher, but my character, Ricky Vaughn, is a flamethrower. With steroids I went from a modest 78 mile-per-hour to a decent 85, which on film can be made to look in the 90s."
Sheen admits he took steroids for three months during filming, but he quickly realised there was a downside to taking performance-enhancing drugs once the movie wrapped.
He adds: "I got injured a lot afterward. Steroids build your muscles, but they don't build your tendons or ligaments. Once you start altering your body's blueprint, things start falling apart."
