How do you know he didn't talk to a Player Rep first? And why are you so positive he is lying?
So far, the entire story is:
Anonymous source: Red Sox used the replay room to steal signs in 2018!! But not in 2019! And not in the postseason!
JD Martinez: Not true at all.
JD was there. Maybe he is not wild about someone screaming that the only time he won a World Series title, he was part of some elaborate cheating scandal. Right now, presumption of guilt really does mena giving more credibility to an anonymous source than to someone willing to use their name.
We don't really know anything, and that doesn't mean MLB and Manfred are creating some massive elaborate cover-up. It's actually possible that nothing will be found because there is nothing to find. Trevor Bauer has said he heard the Astros banging the trash can as far back as 2014. which is interesting inasmuch as it means they might have been cheating this way 2 years prior to hiring Alex Cora. So assuming Cora started the whole scheme in Houston and then obviously (using the completely presumptive "once a cheat, always a cheat" logic) brought it over to Boston might not be anything more than "ironclad innuendo."
That MLB launched an investigation means nothing. They had to after the Fiers bombshell. They also investigated the buzzers based on the tweets of someone claiming to be Carlos Beltran's niece, a claim that operates on two crazy assumptions: 1) Carlos Beltran shares all his nefarious activites with members of his extended family and 2) the Astros kept Beltran in the loop of new cheating techniques after he left the team and went to the Yankees. Both of which are laughable. But... there was an investigation!!!
I have no idea how rampant cheating is throughout the league. But the whole notion of "every rumor means guilt" is taking everything a bit too far. There is a chance they are actually not guilty of anything. And we really don't know anythng until this investigation is complete.
I will say the notion that the media wants to bury this is beyond preposterous. The media LIVES for these moments. Every story is more clickbait, which turns into more revenue dollars. ESPN doesn't care if the Red Sox or Astros or Yankees or Hiroshima Carp are cheating or not. But they do care if people will tune in or click a link to find out about it. Beyond it becoming a convenient excuse for not finding anything out, what possible reason would the media have for wanting to bury this story? They are in the news business, and saying "there is no news" is very bad for that particular business.
And if we learned nothing else from Deflategate, we saw how willing they are to keep a story like that alive...
