Mets Prospect Grant Hartwig Has an Unusual Background and an East-West Arsenal

Grant Hartwig is one of the most promising under-the-radar prospects in the New York Mets system. Moreover, he has one of the more unusual profiles in professional baseball. Signed as an undrafted free agent in 2021, the 25-year-old right-hander has a degree in microbiology and premedical studies from Oxford, Ohio’s Miami University, and he has worked as a medical assistant in a Detroit-area cardiovascular clinic.

Hartwig discussed his Craig Breslow-like background, as well as the movement profiles of his primary pitches, late last season.
