Former Cy Young closer Eric Gagne alleges in his new biography that 80 percent of his Los Angeles Dodgers teammates were using performance-enhancing drugs.

Gagne, who set a major league record while converting 84 consecutive save chances, admits that he used human growth hormone over five cycles in a three-year period toward the end of his career.

"It was sufficient to ruin my health, tarnish my reputation and throw a shadow over the extraordinary performances of my career," Gagne says in the French-language book, titled "Game Over: The Story of Eric Gagne."

Gagne won the 2003 Cy Young while converting all 55 of his save opportunities and posting a 1.20 ERA. He had elbow surgery in 2005 and signed as a free agent with the Texas Rangers before the 2006 season. Gagne signed a minor league deal with the Dodgers in 2010, but was released during spring training and hasn't pitched in the major leagues since 2008.
