Baseball is famously finicky. A terrible team might defeat an elite one on any given night. Screaming line drives are caught for outs all the time, and lazy bloops go for base hits on the regular. Some might even say that the game is difficult to predict. Most observers certainly wouldn't have predicted the Yankees would have owned the league's best record thirty games in (and second-best record today).
Of course, over time, we've gotten a little better at predicting the game, and we've also improved at accounting for the lucky bounces of the ball that can occur.
