"Sean Avery, placed on waivers by the Rangers at noon Friday, told The Post this afternoon that he "guarantee[s]" that a club claiming him "won't ever be sorry."

"I have a lot to prove, and I have a lot of game left after not being allowed to play my game for the last four years," Avery told The Post before returning to New York from Florida, where he was given notice of the move this morning.

"I guarantee that I'll play my a-- off and give everything I have for the team that will give me the chance I wasn't getting [by coach John Tortorella]. That team will be getting a guy who has a lot to prove.

"The GM and coach willing to look past some of the things that are out there about me, I can guarantee that they won't ever be sorry, and neither would my teammates.

"I'm hungry to prove people wrong."

The winger, who opened the season with the AHL Whale after going through waivers at the end of training camp, recorded three goals with a plus-2 rating in 15 games for the Rangers following his Nov. 1 recall during which he played energetically, effectively and with discipline, taking one penalty that left the Rangers shorthanded.

But Avery was anathema to Tortorella, who simply never wanted him around. Avery averaged a total of 7:00 per game in his 15 games, but 5:44 over his last six matches during which he was given a total of 10 third-period shifts.

Avery got the least amount of ice time on the team in each of the last eight games in which he dressed, the last of which came in Buffalo on Dec. 10. He had been scratched from nine straight before getting the word by phone this morning from assistant GM Jim Schoenfeld."
