The Mets selected Lucchesi's contract from Triple-A Syracuse on Monday, Mike Puma of the New York Post reports.
With the Mets having already clinched a playoff spot in winning the first game over Atlanta on Monday, they will turn to Lucchesi in the second contest and save Luis Severino for the wild-card series. Lucchesi has made one start for the Mets this season, allowing five runs over 4.1 frames.
