"He just didn't look right," said Manuel, reflecting on that decision.
While many speculated that there was a problem between Maine and Manuel regarding his pitching, the skipper said it was never about that.
"I was getting on John Maine for hurting John Maine," Manuel said. "When I confronted him, it was about him hurting John Maine."
Maine made nine starts for the Mets this season, compiling a 1-3 record and a 6.13 ERA in just under 40 innings.
When the Mets first placed Maine on the DL, the righty insisted that doctors had told him that he had shoulder tendinitis and that he could pitch with the ailment.
"John Maine wanted the ball regardless of how he felt," said Manuel, adding that he was more concerned with his health than with his desire.
"Even in Florida a few years ago, when I confronted him," Manuel revealed, "he said he wanted to pitch, and I said, 'No, you don't look right, and I'm not going to let you do that.'"
Maine tried to make a comeback, throwing two Minor League rehab starts, but said that he did not feel right after the second start on June 18.
Now with the surgery behind him, Maine can start preparing for the 2011 season.
Manuel reiterated his pleasure in hearing that Maine finally received the treatment he needed.
"He was always tough on John Maine," Manuel said. "That was my argument, why are you so tough on John Maine? I like John Maine."
