I could do that when I was her age. What’s the big deal? But why is a ball girl running out on the field in the place?

EDITED:
According to loyal reader ThatCarmen, this video is a successful viral ad for Gatorade.

At this time the creative team from Element 79 responsible for creating the “Ball Girl,” ad and concept was not givent he green light to talk about the project. The “Ball Girl” video was shot on location during and after an actual game between the Fresno Grizzlies and Tacoma Rainiers. The footage was shot on HD and later edited to look like a Grizzlies batter had hit the ball a out past the left field foul line. The shot and catch was completely choreographed with the ball girl played by stuntwoman Phoenix Brown having marks to hit, and the ball being added later in post. The ball girl was attached to wires was pulled up the wall by 2 stuntmen off to the side.
“It was so low-tech,” Smith said of the stunt. “We had her run, and she would jump, and they just gave her a little extra oomph. It was really very, very simple.”
