Gary Sheffield’s days with the Mets are likely numbered, but the 41-year-old is not ready to retire.

Sheffield told the Boston Globe that he hopes to sign with a team this offseason and expects to hit ‘at least 25 and maybe up to 40 home runs.’ This seems a bit far-fetched for Sheffield after hitting 10 homers in 100 games and 268 at-bats for the power-starved, injury-depleted Mets last season.

“I think I showed when I played regularly I can still play and I can still hit for power,” Sheffield told the Globe. “I’m a righthanded power hitter and I know there’s a need out there. Getting myself in this kind of shape will allow me to move better and not be a one-dimensional player.

“I’ve never worked so hard in the offseason as I have this one. I’m 100 percent dedicated to my training. When people tell me I can’t do something, I prove them wrong. Just like people thought I couldn’t play the outfield last year. I showed them I could. My shoulder came back last year so I can make the throws from the outfield.”

Sheffield, who has 2,689 hits, said his goal is to reach 3,000 before calling it quits. If Sheffield does find a team, it will likely be in a DH role and a return to the Mets is not expected.
