In April, the Orioles lost 2 to Boston, followed by 2 to Detroit, starting the season 1-4.
In May, the Orioles lost two games to Milwaukee, followed by two losses to Houston.
In August, they were swept by the Cubs (after sweeping the White Sox).
In September, they lost 3 straight to the Blue Jays/Yankees combo.
I don't remember people saying "Well, that's surprising. How did that happen?" It's baseball, it happens. While I don't think anyone picked the O's to sweep, most people wouldn't predict three heads if you flipped a coin 3 times, either.
