Through the first dozen starts of 2021, Jacob deGrom drove in more runs at the plate than he allowed on the mound, a statistical impossibility not seen since the dead ball era. This deep dive traces the unorthodox rise of a light-hitting college shortstop who aggressively avoided pitching, then mutated into one of the most terrifying arms of his generation.

From a stoic backyard upbringing to quitting a summer team rather than pitch, we follow how thousands of infield reps gave him elite mechanics before he ever threw a bullpen. We examine the Tommy John setbacks that became incubation chambers for new weapons, a Cy Young that broke the win stat, and a comeback that defied sports science.
