If I was to come to you on a given day and say “today, the Yankees’ starting pitcher is going to throw a one-hitter,” you’re going to feel very, very good about their chances. Add in the fact that said pitcher also allowed no walks, and you’re probably wondering just how close to history did we get, because that’s not that far away from a perfect game, in theory.
However, “in theory” is still just an implication. In one such 1906 game, not only did the Yankees’ pitcher not come super close to a no-hitter/perfect game, not only did he not hold the opponents scoreless, but the Yankees lost the game.
