A catcher is a person who catches something or someone, usually in sports. In most cases, it's about grabbing hold of a ball that's coming your way.
In many sports like baseball and softball, a catcher wears special gear to protect themselves when they're crouched behind home plate, waiting for the pitcher to throw them a ball. The main job of the catcher is to catch the pitches so the other team can't hit it. They also have to communicate with the pitcher about what kind of pitch to throw next and help their teammates stay safe on the field.
Someone or something that catches.
