Though Carlos Beltran already is working out and focusing on next season — which could be the last of his career — the early part of this offseason has been filled with off-field situations, including the arrest on domestic violence charges of former Mets teammate Jose Reyes, as well as the aftermath of CC Sabathia’s recent stint in alcohol rehab.

“I sent a message to support [Reyes],” Beltran said. “It’s very sad news what happened. … I consider him like a brother. He’s a joyous guy, so what happened really surprised me.”

Beltran, who was with Julio Franco on Wednesday for a fundraiser for Bronx Baseball Dreams in TriBeCa, said Reyes replied.

“He knows he made a mistake and he’s gonna do everything he can to make it better,” Beltran said.

As for Sabathia, Beltran attended the pitcher’s recent charity event and said he looked good.

“Sometimes, when you finish treatment, people want to stay away from the public, but he went back to doing positive things,” Beltran said. “This shows me the character that he has.”

As for his own future and playing beyond 2016, Beltran said, “I will see how I finish. I’ve got to make sure I’m healthy, I’ve got to make sure I produce, I’ve got to make sure I can help the team win. I might play another year. I don’t know where.”

Beltran insisted he’s not paying all that much attention to what the Yankees are planning to do this offseason, but was aware of John Ryan Murphy’s trade to Minnesota in exchange for outfielder Aaron Hicks.

“It’s good for Murphy,” Beltran said. “He’s a kid who’s going to get a better opportunity. And the Yankees needed to do what they need to do..”

The arrival of Hicks could make Brett Gardner expendable, but Beltran would like to see him stay in The Bronx.

“Gardner is a plus to us,” Beltran said. “Last year he was an All-Star … but the team makes the decisions.”

As for the rest of the offseason, Beltran put his trust in general manager Brian Cashman.

“If I was retired, I’d give a better opinion, but I cannot throw anyone under the bus,” Beltran said. “Cashman has been in the GM business a long time and he knows what he needs to do.”
