DeGrom’s 2.14 regular-season ERA at Citi Field is the second-lowest for a pitcher since 1920 throwing at least 500 innings at a ballpark, trailing only Sandy Koufax’s 1.37 at Dodger Stadium.

deGrom earned all of it with seven tidy innings in an 8-3 victory that showed why the Rangers have mounted an unlikely playoff push while the Mets might be blowing their chance.

As if that wasn’t painful enough, Jacob deGrom made his return to Citi Field and largely shut his former down over the course of seven innings.
