Nice, Rick! You are certainly shooting fast enough at 1/4000 sec. If you use the auto ISO feature you don't need to worry (as much) about your camera speed. If you have questions about how to set up your camera for these kinds of shots, go to YouTube. Once you have the hang of it you can switch between auto ISO mode and other modes pretty quickly. Based on your EXIF info you could afford to go to a higher f-stop and still maintain a relatively low ISO number and a quick shutter speed.
