One player hitting three home runs in one game is rightly seen as an impressive accomplishment. Reggie Jackson hitting three home runs in Game Six of the 1977 World Series is one of the most replayed moments in Yankees' history.
On May 15, 1923, Wally Schang "accomplished" a feat that is arguably more amazing than hitting three home runs in a game. It's not more amazing in terms of player performance. Schang didn't have the biggest hand in his performance at the plate that day. I mean in turns of pure amazement, what happened to him that day is arguably more ridiculous than if he had hit three home runs.
