Alycia Baumgardner’s positive drug test affects more than just the fighter herself, according to her rival, Mikaela Mayer.

What irks Mayer the most is that other fighters will have to live with the public’s suspicions that “everyone is on that stuff.”

Last month, Baumgardner, the undisputed junior lightweight champion, was revealed to have tested positive for two banned performance-enhancing drugs ahead of her July 15 bout against Christina Linardatou. Baumgardner has maintained that she is innocent, saying in a statement that two test results produced immediately after her July 15 bout both came back negative.

Mayer (18-1, 5 KOs), who lost for the first time in her professional career to Baumgardner last October in their lightweight unification bout, has mostly refrained from jibing at her adversary.

But in a recent interview, ahead of her 10-round junior welterweight bout with Silvia Bortot, Baumgardner made it clear she remains highly annoyed by the impact Baumgardner’s positive test could have on fighters who play by the rules.

“She screwed up big time,” Mayer said on The Boxing with Chris Mannix Podcast. “Now everyone thinks that she needed to cheat to get there. Her credibility is shot. It’s gone. Not only that, it doesn’t matter the consequences she faces. It’ll never take back the way it has affected the 135-pound division over the last couple of years. It has affected a lot of people a lot of different ways. She can say she wasn’t on it for my fight or Terry Harper’s fight and that’s the problem with this, it’s always going to be in question, right?

“People are always going to wonder. Her credibility is gone now. So we don’t know. But everybody has to go through due process. I guess we’ll find out when they do the investigation. But I personally don’t see how she’s going to get away with it. It’s not like she tested for a diuretic, right? These were some serious hardcore PEDs, and two of them.

“I feel bad for her. I think her career is f----- now. But I feel bad for her. She needs to go handle that. It’s not my problem. It’s her problem. It’s my problem when it comes to boxing and keeping the sport pure. What pisses me off is now everyone else is now saying, ‘Oh everyone is on that stuff. Oh, everyone is on it. Everyone is juicing now.' And that’s not true. There’s plenty of us out here competing clean and honest.”

Baumgardner is the third Matchroom fighter to run afoul of anti-doping tests in recent memory. In the same month, heavyweight Dillian Whyte failed a drug test leading up to his fight with Anthony Joshua, and last year Conor Benn tested positive for a banned substance twice.
