What does a mat girl do in wrestling?

Answer 1

My assumption is you are referring to real Wrestling and not prefessional performances. A mat girl or mat maid can also be referred to (and possibly more politically correct now days) as a team manager. They typically handle items such as keeping individual/team score books, carrying/filling water bottles, responsible for the coaches equipment bag and may possibly act as a student trainer applying tape, bandages, and ice to injuries. They are vital to a coach and team when there for more than the socializing.
