Mets starting pitcher John Maine didn't want to leave Thursday's start against the Nationals after walking the leadoff batter.

Maine angrily talked with Jerry Manuel in the dugout after the manager pulled the right-hander five pitches into the start.

"Look, I've felt pain for two years, but I'm over that," said Maine, whose velocity hasn't returned since Sept. 30, 2008 surgery to remove a bony growth from his right shoulder socket. "I don't care about that. I'm well enough to pitch. I wanted to pitch. That's the bottom line."

Manuel said: "We got into a little exchange about that, and I told him I was trying to protect his best interests, and that I know that he's a competitor. ... I don't want to be responsible for a young man's career."
