Some current and former members of the Mariners, including Phillies lefthander Jamie Moyer, are disputing the claim of former Seattle outfielder Shane Monahan that the clubhouse culture led him to use steroids and amphetamines, according to

Monahan openly admitted to that he used performance-enhancing drugs. Moyer disputed Monahan's recollections directly.

"I can tell you that I was there for 10 years and I never saw anyone take steroids," Moyer said, according to the Seattle Times.

"This will be my 20th year in the major leagues, and I don't even know what a steroid looks like. If I have to start relying on those things, after so many years in the game, then it's time to pack it in. That's the way I look at things."

Mariners president Chuck Armstrong told the newspaper that the team was unaware of the validity of any of Monahan's allegations.

"We're surprised and disappointed," Armstrong said. "As I've said all along, we fully support the commissioner's initiatives. There is now testing for amphetamines, and access to the clubhouse has been tightened a great deal since those days."

Ken Griffey Jr., the face of the Mariners franchise during his 11-season tenure in Seattle, declined comment through his agent.

Monahan never was mentioned in the Mitchell report on steroid use in baseball.The paper also reported that several Mariners players who were named in the Mitchell report did play in Seattle during Monahan's brief stay in the majors, including former Phillie Ryan Franklin, Glenallen Hill, David Segui and Todd Williams. *
