Pitcher Eric Gagne, the 2003 Cy Young Award-winning closer, claims that “80 percent” of his Los Angeles Dodgers teammates used performance-enhancing drugs during his time with L.A.

Gagne made the claim in his biography, “Game Over: The Story of Eric Gagne,” according to ESPN Los Angeles.

The former Dodger, Red Sox, Ranger and Brewer, who was the first relief pitcher in 11 years to win the Cy Young when he took home the award in 2003, also admitted to using performance-enhancing drugs himself.

Gagne, a Montreal native, was one of 89 baseball players named in the infamous Mitchell Report commissioned by baseball that details the use of performance enhancing drugs in the game. The report was published in 2007, a year before Gagne retired in 2008.

"I was intimately aware of the clubhouse in which I lived. I would say that 80 percent of the Dodgers players were consuming them," Gagne says in the biography, ESPN Los Angeles reported.

Gagne said he took human growth hormone over three years at the tail end of his career and sounded remorseful about his drug use in his book.

"It was sufficient to ruin my health, tarnish my reputation and throw a shadow over the extraordinary performances of my career," he said.

Controversy over whether elite players from baseball’s “Steroid Era” should be eligible for the Hall of Fame has been at the forefront of discussion ever since Mark McGwire’s name appeared on the ballot (McGwire has yet to be elected to the Hall.)

As Fox Sports reported: “It's a tricky subject and one that isn't going away any time soon. Gagne wouldn't appear on many Hall of Fame ballots when it comes time to vote, but one has to wonder if we're a few years away from the next book revealing that Cooperstown has already been infiltrated by a PED user.”
