If I was a betting man (I'm not), my best estimate is it's a focus accuracy issue. In the first image, looking at the grass, the focus plane appears to me to be just beyond the ball and just in front of the child on the right. In the second image, it looks like optimum focus is between the two girls. In the third, I estimate the best focus to be just beyond the two girls.
If I'm right, then this can be either a hardware issue or an operator issue. I suggest a focus test with the camera mounted on a tripod to remove camera shake from the test, and a shutter speed quite high, 1/2000 or faster to take shutter speed out of the test (use high ISO as needed - your aren't testing the noise level in your images, so don't worry about noise level). Careful aim will be essential, as well as knowing exactly where the aim was when the shot was captured. You should use a complex subject with lots of detailed objects to allow you to evaluate the accuracy of focus. Take several shots without moving the camera or changing camera settings, except defocus the lens after each shot and force the autofocus system to refocus each shot. Examination of the images should tell you if the spot you aimed at is the best focus in the resulting image. Looking at the several shots should show you how consistent the autofocus is.
If the test shows the focus accuracy is off, then the camera and/or lens needs attention. I don't know if your model camera allows for focus tuning, but if it does, that would be your next step.
If the accuracy in the test is satisfactory, then getting your aim better will be the solution. If this is the case, you should try the various focus modes your camera offers (team practices are good for this), and based on your results, then practice, practice, practice. Shooting subjects that are in motion is skill that is separate from shooting stationary subjects. There are tutorials online that can help (Google can be your friend).
