"It's a sad day," Los Angeles Angels manager Mike Scioscia said. "It's a black eye when something like this happens."
New York Yankees pitcher CC Sabathia, Braun's former teammate in Milwaukee, said he was shocked.
"I never would have thought it, but I guess you never know," Sabathia explained.
Some players were more forgiving.
"He stepped up. It's just like when you get a ticket, a speeding ticket," Tigers outfielder Torii Hunter said. "You know you were speeding. You get a ticket and you go and you do your time or pay your speeding ticket, then you're doing what you're supposed to do. That's what Braunie is doing. Everybody makes mistakes. It takes a man to forgive him. If you don't forgive him, then are you a man?"
Bay thinks Braun could have handled his situation differently.
"If you look at the guys who have done stuff and just come out and admit it, a lot of guys don't remember who those guys were," Bay said. "But the guys who run up and down and say, 'No, no,' and then it gets drug through the mud 10 times worse, it makes it tougher on themselves and the rest of us."
It appears more penalties are coming, too.
Braun was one of more than a dozen players targeted by MLB, including injured Yankees star Alex Rodriguez, following a report by Miami New Times in January that they had been connected with Biogenesis of America, a now-closed anti-aging clinic.
"The guys that are cheating or whatever are taking something away from the other players. They're lying to the fans, they're lying to their teammates, they're lying to their GMs, their owners, and they're going to get caught," Angels pitcher C.J. Wilson said.
Braun addressed his stunned Brewers teammates Monday afternoon. Second baseman Rickie Weeks described the slugger as "somber" and "embarrassed."
"I've said all along he doesn't need that stuff to perform," catcher Jonathan Lucroy said. "I don't know why he ever took it."
Lucroy acknowledged he initially felt deceived. But he said Brewers players were supportive, and he forgives Braun.
"I don't think anybody here is going to hold a grudge," Lucroy said. "He was depressed, but at the same time he felt a lot of weight come off his shoulder, come off his chest. That's a tough burden to bear, withholding the truth for so long."
