The Mets will be in San Francisco on Friday night, just shy of the 10-year anniversary of the non-trade that helped turn their 2015 season around, the one that involved (or at least almost involved) Wilmer Flores.

Flores is now in his 13th year in the majors — and sixth with the Giants — but anyone who was around Queens during their last World Series season remembers the infielder’s role in helping get the Mets back to October.

It started on July 29, 2015, as the Mets were in the process of losing to the Padres at Citi Field and reports surfaced that Flores had been traded to the Brewers — along with Zack Wheeler — in exchange for Carlos Gomez.

With the crowd buzzing, word got to Flores that he had been traded by the team he had signed with out of Venezuela in 2007.
