From MLB Trade Rumors article on the matter:
Cora again reiterated that the Red Sox haven’t made any decisions. “He’s going to work out as the third baseman. And we’re going to make decisions accordingly. Here, it’s not about Bregman or Devers or Cora,” the manager said. “It’s for the Boston Red Sox. Whatever decision we make is going to be for the benefit of the team.”
Interestingly, Cora acknowledged that the Red Sox promised Devers that he’d be their long-term third baseman at the time the sides agreed on a 10-year extension in January 2023. That agreement came under a previous front office regime, as then-chief baseball officer Chaim Bloom was fired eight months later. Craig Breslow is now running baseball operations. Cora downplayed the significance of that promise as a result, saying it was under “different leadership. That was under Chaim” (relayed by Jen McCaffrey of The Athletic). Of course, Cora was the manager at the time of the extension, so there hasn’t been a leadership change in the clubhouse.
Devers was asked whether he’d seek a trade if the Red Sox forced him to move off third base. He didn’t rule that out but said it hasn’t been a focus. “That’s a tough answer to give. I haven’t given it much thought. I’ve been here my entire career,” he said (via McCaffrey). “I haven’t asked myself that question. I’m open to listening. I’m not close to those conversations.”
