Perhaps he can rehab to where surgery isn’t needed, but those odds are getting long.

Yes, yes, it is his body and nobody can force surgery upon him, but reading between the lines, if it doesn’t happen, Parnell will risk not being ready for spring training and consequently pushing the envelope to the point of further injury.

Who can’t see the prospect of him slowly being worked into shape during spring training, and perhaps forcing the issue until he hears a “pop’’ and goes on the disabled list again with surgery being the only option?

If so, then say good-bye to 2014.

Parnell said if he doesn’t have surgery soon, there will come a time when the Mets will “push for it,’’ but until then it’s only about therapy now.

“My ultimate goal is to be ready for spring training so I can be here for the team next year,’’ said Parnell, whose doctors told him it is a five-month process – and, of course, you always add one – after surgery to be ready.

Backdating from mid-January, when he would begin off-season throwing, if he were to have it tomorrow there’s already a good chance he wouldn’t be ready.

Parnell, who last pitched July 30 and went on the disabled list, Aug. 6, is practicing in wishful thinking if he believes he’ll be back this year. Parnell said he’s supposed to be re-examined next week, but after that there should be serious consideration of a second opinion if he’s to have any chance of being ready for the start of next season.

Parnell isn’t the only Mets pitcher facing surgery this winter.

Jeremy Hefner as a partial tear of the MCL in his right elbow, but is considering a second opinion. Hefner was the Mets’ hottest pitching heading into the All-Star break, but fell flat at the start of the second half and was replaced in the rotation.

Jenrry Mejia, whom the Mets projected would need surgery to remove a bone spur in this right elbow at the time he was promoted, aggravated the injury twice and went on the disabled list last weekend. He’s to have surgery within the next two weeks.

Ironically, Parnell and Hefner were among the chips the Mets were considering dealing at the trade deadline.
