Skip Schumaker of the Los Angeles Dodgers said Braun, the 2011 National League Most Valuable Player for the Milwaukee Brewers, let him down.
"Watching him talk right now makes me sick,'' Schumaker said. "I have an autographed Braun jersey in my baseball room that I'll be taking down. I don't want my son identifying what I've worked so hard to get to and work so hard to have I don't want him comparing Braun to me.''
Matt Kemp of the Los Angeles Dodgers, who finished second to Braun in the 2011 MVP vote, said the Milwaukee slugger should be stripped of the honor.
"We had conversations, and I considered him a friend,'' Kemp said. "I don't think anybody likes to be lied to, and I feel like a lot of people have felt betrayed.''
New York Yankees manager Joe Girardi said Braun was guilty.
"You don't accept a deal unless you're guilty,'' he said.
"It's another black eye for our game. I know this game is very resilient, and there's been a lot of scandals over the years, but you get tired of it,'' Girardi added.
He may soon facing his own problem with a teammate.
More than a dozen players have been targeted by MLB in its probe of the closed anti-aging clinic Biogenesis of America, including three-time AL MVP Alex Rodriguez of the Yankees.
The next step will be for MLB to inform the union of additional players it intends to penalize, which could happen as early as a meeting on Thursday, a person familiar with the probe said, speaking on condition of anonymity because no statements were authorized.
New York expects A-Rod could face a much harsher penalty than the one Braun agreed to, a second person familiar with the case said, also speaking on condition of anonymity because no statements were authorized.
The Yankees anticipate Rodriguez could be accused of using PEDs over multiple seasons, of recruiting other athletes for the clinic, of attempting to obstruct MLB's investigation, and of not being truthful with MLB in the past when he discussed his relationship with Dr. Anthony Galea, who pleaded guilty two years go to a U.S. federal charge of bringing unapproved drugs from Canada into the United States.
Despite Braun's suspension, Kemp has no shot at claiming the MVP trophy. The Baseball Writers' Association of America has said repeatedly that it will not revisit any of its award votes.
"The decision was already made. He won it,'' said Jack O'Connell, the BBWAA's secretary-treasurer.
