Astros whistleblower Mike Fiers said Thursday he has received death threats since he exposed Houston’s 2017 electronic sign-stealing scheme, but is not too worried. 

“Whatever, I don’t care,” Fiers, now with the Oakland Athletics, told the San Francisco Chronicle. “I’ve dealt with a lot of death threats before. It’s just another thing on my plate.” 

Fiers, a former Astros pitcher, revealed details of the sign-stealing scandal they employed during the 2017 World Series championship season in November to The Athletic, which led to an investigation by Major League Baseball. 

Despite the harsh backlash this spring from players, Fiers is not worried about his well being or think he needs extra security from MLB.

“I’m not asking for extra security,” Fiers told The Athletic on Wednesday. “I’m here to play baseball and I can defend myself, if anything. We do have National League games and I’m going to have to get into the box (to hit) just like everybody else. It’s part of the game. If they decide to throw at me, then they throw at me. There’s nothing much you can do about it.”

Fiers isn’t the only one who has received threats. Astros outfielder Josh Reddick told ESPN he has received threats via social media as well as some of his teammates.
