Ball boy

In professional tournaments, every court will have a trained squad of ball boys/girls with positionings and movements designed for maximum efficiency, while also not interfering with active play.

In 2006, the IFAB Laws of the Game of association football were changed to allow multiple balls to be used under the direction of a referee.

As ball kids are stationed on the field, albeit in foul territory, they can occasionally interfere with play; such events are governed by Rule 6.01(d), the main point of which is that if the interference is unintentional, any live ball remains alive and in play.

The blonde beauty unfortunately snagged a ball that was fair and live in a Tampa Bay Rays game, throwing it to the fans.

[11] Since 1992, the San Francisco Giants have employed older men as "balldudes", instead of the traditional youths.
