As the Mets, a team with World Series aspirations in April, drift further and further out of contention, speculation surrounding Terry Collins’ job security as manager continues to grow.

His in-game decision making has become increasingly suspect this season, and the fact that the Mets aren’t winning hasn’t masked those poor decisions as it did the past two years.

It still remains to be seen whether the Mets will actually fire him; he’s already presided over four losing seasons in six years as manager, and looks to be well on his way to a fifth in seven years.

A recent New York Post report said that Sandy Alderson is beginning to document Collins’ mistakes; it stopped short of saying he was on the hot seat, but that is not exactly a resounding vote of confidence for the Mets’ skipper.

The Mets have given Collins a longer leash than perhaps any manager in recent memory, so it’s totally plausible to think that they wouldn’t fire him this season.

If they do opt to move on, they won’t have much to chose from.

It will probably be difficult to get guys with solid managerial experience like Ron Gardenhire or Fredi Gonzalez aboard midseason, since they currently have positions on other coaching staffs.

They could all be top-tier names next year, but the Mets are probably not going to have that long of a list to chose from during this season.

With that being said, here are six guys who could possibly replace Collins if the Mets do decide to fire him, which is still a big if:

Dick Scott:

 The Mets’ bench coach would probably be the most likely person to take over in the interim should Collins get the boot.

Scott has been the Mets’ bench coach since 2016 and worked in the front office prior to that under Sandy Alderson.

His familiarity with the team and relationship with the front office makes him a prime candidate to take over if the Mets decide to move on from Collins.

Glenn Sherlock:

The Mets’ third base coach has spent over two decades on MLB coaching staffs. Prior to this season, he had been an assistant with the Diamondbacks since the team’s inception in 1998– this obviously includes their World Series championship in 2001 and four other playoff appearances outside of that. He has more coaching experience than just about anyone on the Mets’ staff.

Pedro Lopez:

Lopez has been in the Mets’ organization since 2008.

He’s currently the Las Vegas 51s manager, and was at the helm for Double-A Binghamton from 2012-2016.

He has a lifetime managerial record of 396-360, so he could also get consideration if Collins goes.

Walt Weiss:

 Weiss is out of baseball after serving as Rockies manager for the past four seasons where he went an underwhelming 283-365.

However, he has experience with Sandy Alderson: He played for the A’s while he was the GM from 1987-1992, and was a part of their last World Series championship team in 1989.

Weiss isn’t an ideal choice, but his availability and experience with Alderson could make him a speculative candidate.

Robin Ventura:

As far as available managers go, Ventura might be the best of a bad lot.

He went 375-435 as manager of the White Sox from 2012-2016, boasting an 85-77 record in 2012.

Ventura also has experience playing with the Mets, as their third baseman from 1999-2001. That experience could make him an interesting fit with this year’s team.

Bobby Valentine:

Just kidding. But he is around, if the Mets would ever consider that.

David Wright:

The odds of this happening are between slim and none. And probably lean closer to none.

But a lot of other teams have made it a trend to hire managers without any coaching experience (Mike Matheny, Craig Counsell), and Wright has been universally praised for his clubhouse presence.

With his chances of playing again growing slimmer by the day, Wright might not actually be the worst choice here.
