It is my ball!

A woman in a white shirt and white pants stands up from a stadium seat, turns, and walks away from the camera, moving up a set of stairs. She is initially seated next to a young girl in a white shirt and a boy in a red cap, and the girl follows her, walking up the stairs after her. The scene takes place in a stadium with a large yellow 'N' on the floor and a lower third graphic reading "MINUTE MAID PARK - HOUSTON FRIDAY".
