Ball Cannon

A lot of sports involve striking a ball that is moving at high speed. To allow people to practice, many of these sports have machines designed to launch balls at a player: bowling machines for cricket, pitching machines for baseball and softball, tennis ball servers for tennis, etc.

Given these machines are essentially miniature cannons, designed to launch projectiles, it is not surprising that, in fiction at least, these devices have been turned to lethal intent. This trope is for when a ball launching machine is used to kill someone.
