The Mets’ use of a thumbs-down gesture as a jab at the fans who’ve booed them at Citi Field leaves many questions for the team. Here’s a look at some of the answers to those queries: Q&A

Q: Internally how angry are the Mets at the involved players? A: Steve Cohen isn’t happy

Q: Does this seal Baez’s fate as far as returning to the Mets next season?

Ultimately, more traditional baseball metrics will serve as the barometer regarding his future.
