Definition & Meaning of "upcast"in English

What is an "upcast"?

In bowling, an upcast refers to a type of throw where the player releases the ball with a high, upward motion. This technique causes the ball to rise slightly as it leaves the player's hand before it drops and rolls down the lane. The upcast is often used to help control the ball's path or to avoid obstacles on the lane. While not a common throw, it may be employed in specific situations where a different approach is needed for accuracy or pin action.
