The Mets are about to approach a franchise crossroads.

If wins begin to commence, the idea of New York making a run at the postseason and acting as buyers in July isn’t hard to imagine.

But if a season-long malaise doesn’t clear, changes are almost sure to go down in Flushing. That could start with a change at manager, but it certainly won’t end there. A fire sale could go down before this summer’s trade deadline.

If the Mets are sellers, expect Noah Syndergaard to be in demand.

MLB.com’s Anthony Castrovince is already going down that round and projecting Syndergaard to the San Diego Padres as a “not-so-crazy” trade idea.

Remember when this was a thing last winter? It could become a thing again.

Syndergaard has pitched much better than his overall numbers (4.50 ERA, 87 ERA+) suggest. Though opponents have a .311 wOBA against him, their xwOBA, based on quality of contact, is .266, per Statcast. He’s under contractual control through 2021, which would make him a major trade asset this summer, and the Mets… well, the Mets don’t currently inspire much confidence that they’ll be in the thick of things this summer.

So this is another “stay-tuned” situation. A deal fronted by Mackenzie Gore and Francisco Mejía could have appeal for the Padres and Mets alike. But it doesn’t have to be Thor. Whichever high-impact starting arms become available this summer (Trevor Bauer, perhaps?), the Padres undoubtedly have the pieces and possibly have the incentive to get a deal done. Chris Paddack’s innings limit will rear its ugly head eventually, and a stabilizing force like a Syndergaard could go a long way toward separating San Diego in what figures to be a deep NL pack.

Gorde and Mejia would be a strong starting point for a blockbuster, and one the Mets may not be able to turn down if a sell off actually happens by general manager Brodie Van Wagenen.
