An underhanded throw is a type of throwing motion used in sports such as baseball, softball, and cricket. It involves the player throwing the ball with their palm facing downwards, rather than up. This type of throw is often used to deceive the opposing team, as it is difficult to predict where the ball will go. The two most common terms for an underhanded throw are 'TOSS' (4 letters) and 'LOB' (3 letters).
