I've heard the rumor as well. Reportedly the Mets would give up 3B/1B prospect Mark Vientos.

Vientos is an interesting prospect, he's hitting .852 OPS with 18 HRs in AAA Syracuse. But here's the scary thing. If this trade goes through, does this give Chaim 'I love trading away homegrown talent' Bloom the perfect excuse to get rid of Rafael Devers next season?
In theory I don't mind giving up a 34 year old DH in Martinez, even though he's one of our best hitters. He's aging, and he's still not as important arguably as a position player. Giving up Vazquez would be a tough pill to swallow though.
He's our starting catcher and one of the better hitting catchers in the MLB.
There's no 'ready' position for Vientos unless we kick him to 1st base, which is a less valued position than 3B, or we trade away Devers to give him a place to play.
If this deal were to happen, then it's likely that Bloom deals away Devers to 'make room' for Vientos and then deals away Bogaerts next season, to 'make room' for Story.
Bloom can't deal Bogaerts now because Story just got diagnosed with a hairline wrist fracture that will put him out for at LEAST 1 month.
But I'm pretty sure Bloom will dismantle this team to remake in his own image, just seems to have that kind of ego based on his past history of dealings.
