SPRINGFIELD -- For five hours on Saturday morning at Winter Weekend, Red Sox players and coaches delivered basically the same message in regards to the 2018 cheating scandal: We're not at liberty to say anything until the league finishes its investigation.

And then J.D. Martinez stepped in front of the cameras.

The slugging DH, who earlier this offseason chose to remain in Boston rather than exercise an opt-out in his contract, minced no words when asked if the Red Sox did anything wrong during their championship 2018 season.

"You know, it sucks, to be honest with you," he said of the investigation. "It does suck. But you know what? I know I'm excited for the investigation to be over with just so that they can see that there was nothing going on here."

So he believes the team is innocent of the charges that it used the replay room to steal opposing signs in real time?

"I believe that, yes," Martinez said.

And what gives Martinez this confidence, despite a report to the contrary in The Athletic claiming that the Red Sox stole signs?

"Because I was in there," he said. "I saw what was. . . . Straight up, everyone seems to forget that in 2017 and '16 this team was a really good team. This team won 93 games those two years and then we just got better."

Martinez spoke without hesitation, and also saluted departed manager Alex Cora, while offering some insight into why Cora decided to leave the team.

"Kind of heartbroken about it," he said. "I talked to him before and I understood his side of it. He didn't want to be a distraction going into the season. I know it was wearing on him and his family, so I obviously feel for him and I wish him the best. But I know he played a big, big role for our team and he was one of my favorites, if not my favorite manager that I've had. It's going to be tough."
