Baseball is an unpredictable game. Randomness can and will come into play if we analyze it in small samples. Any given player can go on a 10-for-25 hot streak while hitting mostly bloop singles and perfectly placed weak liners, and any superstar can go 0-for-the-series while scalding balls right at defenders.
That’s why we like large sample sizes, to eliminate some of the randomness and get a better idea of a hitter or pitcher’s real skill level. All of this means that both batters and hurlers can get lucky or unlucky for an extended period of time. The Yankees, as a team, are no exception.
