On July 26, 1879, McCormick, the Syracuse Stars' starting pitcher, hit a first-inning homer ^[2] to beat Tommy Bond and the Boston Red Stockings, 1–0. This is the first and, most likely, will be the only occurrence in major league history that a pitcher will record a 1–0 victory with his own first inning round-tripper being the game's lone run.
