Mets pitcher Matt Harvey has lost his spot in the starting rotation, manager Mickey Callaway announced Saturday.

Harvey, who will be available coming out of the bullpen starting Tuesday, was not happy about the decision.

"It's the decision that they made. I have to suck it up and go out there and do everything I can to get things back in gear," he said. "I don't have to agree with it, but I have to go out there and do the best I can to get things going and do everything I can to help this team get back to where I believe I can help this team, and that's as a starter.

"On a scale of 1 to 10, obviously I'm at a 10 with being pissed off, but my performance hasn't been there, and I just have to do whatever I have to do to get back in the starting rotation. And that's right now go to the bullpen and work on some things, get some things back to where they need to be and get my s--- in order and figure it out."
