The names Todd Hundley and Carlos Beltran have their place in New York Mets history. Each hit 41 home runs while employed by the Metropolitans, tying for a franchise record for the single-season record. Though it pales in comparison to the MLB record, it’s a fine enough total.
There haven’t been many challengers. Mike Piazza is the only other guy to reach 40, an achievement accomplished in 1999.
On the current Mets roster, the likeliest candidate to set a new standard might be Michael Conforto. We saw the kid hit 27 home runs in 2017 with only 440 plate appearances.
