 The Mets promoted deGrom to the major leagues on May 12 , 2014 , after Gonzalez <unk> was placed on the disabled list . The Mets planned to use deGrom in relief , but an injury to Dillon <unk> required the Mets to insert him into their starting rotation . DeGrom made his major league debut on May 15 against cross @-@ town rival New York Yankees in <unk> Field . He faced fellow rookie Chase <unk> , also making his MLB debut . He pitched seven innings , allowing only one run and striking out six , but the Yankees shut out the Mets and won 1 – 0 . DeGrom also collected his first MLB hit in the game in his first career at bat . It was the first hit by a Mets pitcher in the 2014 season ending an 0 @-@ for @-@ 64 <unk> streak , the worst collective mark by a pitching staff to begin a season in MLB history .
