"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," Sheen, who plays the role of a baseball player, told Playboy magazine.
"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," he added.
