The Mets playoff hopes are looking far more uncertain. Plain and simple.

I know as a fan, you are kind of obligated to believe. But at 10.5 games out of the National League East and 12.5 out of the Wild Card, the Mets chances are just too remote to roll the dice by not selling at the deadline.

Not selling in hopes of remote playoff chances has bitten the Mets in the behind before; the team held on to Jose Reyes in hopes that they could possibly make a run at the Wild Card when they were 6-8 games back for most of the summer of 2011.

They didn’t do that. With this inaction, the Mets lost a chance at a top-tier prospect and failed to even keep Reyes in free agency.

The Mets should never make that mistake again.

This doesn’t mean that the Mets window is closed. This doesn’t mean that they can’t win next year. This doesn’t mean it’s time to give up hope on the rotation, the prospects, or heck even on Matt Harvey.

The team has to do everything it can to re-tool, without sacrificing long-term pieces, to be in position to contend in 2018 and beyond.

Here are five guys the Mets should look to sell:

JAY BRUCE

Jay Bruce will probably be the most talked-about Met at the deadline this year, given how well he has played and because he is a free agent at the end of the season.

Since the Mets have Michael Conforto and Yoenis Cespedes holding down outfield spots for years to come, the Amazin’s need not sign Bruce to a long-term contract.

A player who’s on pace for 43 home runs and 112 RBI should net something that’s at least palatable back in a trade.

LUCAS DUDA

The Mets have Dominic Smith waiting in the wings– the 2013 first-round pick is batting .318/.372/.464 in Triple-A this year and could be ready for the Big Leagues by 2018. If he’s not, the Mets could look for a one-year veteran stop-gap to fill the void.

Duda would probably command more than a one-year deal in free agency, so it’s tough to see how he fits in for the future assuming the Mets are planning on having Smith play first base.

A team like the Yankees could use Duda to play first; he would probably do very well with that short porch in right.

ASDRUBAL CABRERA

Asdrubal Cabrera hasn’t been as good a hitter this year as he was in 2015, but he could be appealing to a contender at $8.25 million this season, and an $8.5 million option next season with a $2 million buyout.

The Mets will probably need to make room for Amed Rosario soon, and assuming they can keep Neil Walker (which they hopefully do), they won’t really have room for Cabrera anywhere.

CURTIS GRANDERSON

Curtis Granderson has been much better recently after an awful first two months of the season.

And since he’s a free agent at the end of the year, the Mets should look to get something out of him over the long term.

Granderson could be appealing to a playoff contender in either the National League as outfield security or American League as a designated hitter or fourth outfielder.

His veteran skill set and clubhouse presence make Granderson an appealing option for a team looking to make a deep playoff run.

ADDISON REED

Every contender needs a little bit of bullpen help and affordable relief pitchers with ample closing experience don’t grow on trees.

Addison Reed has 117 saves over his career, and a 2.09 ERA during his time with the Mets.

Sandy Alderson is probably going to get a lot of calls from contenders about Reed, who is someone that could be best suited as a setup man for a team with an established closer.
