That kind of throw is called a breaking pitch.

这种投掷被称为突破投球。

Breaking pitches take advantage of what’s known as the Magnus effect, where the ball’s spin interferes with the air around it in a way that changes its direction.

突破投球利用了所谓的马格纳斯效应，即球的旋转会以改变其方向的方式干扰周围的空气。

And there are lots of different types of breaking pitches, but one of the most popular ones is the curveball, where the ball curves directly downward faster than normal.

有很多不同类型的突破投球， 但最受欢迎的一种是曲线球，球直接向下弯曲的速度比正常情况更快。
