You want to be shooting 1/800 or faster for action. Outdoors, you have plenty of light for this. No need to shoot at ISO 200, raise it to 400.

flash freezes action
those also look a bit overexposed
might be worth learning how to uses flashes and get an external one with a remote trigger
With the exception of the overexposed comment, disregard this post. Flash freezes action only in the absence of ambient light in your exposure which is not the case when shooting during the day. Off camera flash only changes your light angle and with the exception of some of the new TTL capable triggers, still locks you into 1/250 or less shutter speeds because of sync limitations.
There is really no situation that using flashes in a daylight environment will fix the issue you are trying to improve. HSS can give you options for improving fill lighting but that is about all you will gain with a flash.
Fast shutter speed, DOF control, even lighting and proper exposure are the answer.
