The New York Yankees' worst-kept secret is that their biggest player development success ... maybe ever ... ascribes a good deal of his growth to a hitting coach that isn't on the team's payroll. Aaron Judge is a devotee of Richard Schenck, aka Teacherman, an entity that is almost impossible to accurately describe.
Judge is a massive believer in the quirky mercenary, prone to occasional brash and abrasive outbursts, and will often call upon him in times of woe to help him rebuild his offensive portfolio. Schenck will fly into road cities to meet Judge in the dark of night; as of 2024, the two convened "every two weeks," a fact that became publicly known when Schenck called the Yankees' player development "terrible" on the offensive side.
