"We haven't even thought about [trading Lester]," said Cherington. "Jon's focus is to go out and pitch every five days and help us win, and he's done a very good job of that this year. We're trying to support him in any way we can.
"Our position hasn't changed. We hope to have a conversation again about his contract. We'd love to find a way to keep him here. But right now we're just trying to win games and stay in this thing. I believe we will. When we do, we're going to want Jon Lester pitching for us down the stretch."
Though the All-Star break -- or thereabouts -- is particularly a time when the Red Sox talk to agents about extending their own players, Cherington didn't want to get into specifics.
"We don't have a plan, and we don't have a date," Cherington said. "I wouldn't read anything to it other than that it hasn't happened yet, and there's probably a time that makes sense for both parties, and we just haven't gotten to that."
