f/2.8 at a short distance = shallow depth of field.

Suggests you are shooting down at them. Try getting down on their level.
Use the SB600 with a diffuser or bounced, ISO 800, f/5.6, 1/125. This should get you in focus with a reasonable DOF and frozen action.

Moving targets should be shot in af-continuous. That way the camera keeps focusing as the subject moves.

AF-C Dynamic group or single-point Lock-on (a5) set to short or off Highly recommend the af-on button.
