Righthander Dennis "Oil Can" Boyd admitted during an interview that he was under the influence of cocaine before "two-thirds" of his games with the Boston Red Sox.

Boyd told WBZ NewsRadio on Wednesday that his cocaine use was frequent - and that his teammates knew of it.

"Oh yeah, at every ballpark. There wasn't one ballpark that I probably didn't stay up all night, until 4 or 5 in the morning, and the same thing is still in your system. It's not like you have time to go do it while in the game, which I had done that.

"Some of the best games I've ever, ever pitched in the major leagues, I stayed up all night; I'd say two-thirds of them. If I had went to bed, I would have won 150 ballgames in the time span that I played. I feel like my career was cut short for a lot of reasons, but I wasn't doing anything that hundreds of ballplayers weren't doing at the time, because that's how I learned it."

Boyd is promoting his autobiography "They Call Me Oil Can: My Life in Baseball."

From 1982-91, Boyd posted a 78-77 career mark with a 4.04 ERA with the Montreal Expos, Texas Rangers and Red Sox.
