A revelatory June has turned the Mets from projected sellers to projected buyers.

But now that we’re in July, exactly four weeks from the trade deadline, do the Mets know what to buy?

Yes, of course they need a relief pitcher. Or maybe relief pitchers, plural. How many should they acquire? Are there in-house options who can emerge in the second half whom the Mets can count upon?

They don’t know, which represents a complication that probably won’t be solved this month.
