Baseball and softball are difficult to shoot at times, generally not games with a lot of good action and when it does happen you almost have to be ahead of it, anticipate what's going to happen. Just keep at it. Try and keep the backgrounds in mind when shooting and avoid clutter and in the case of the shot posted, everything. When people start shooting they are usually so fixed on the subject they fail to look past what is going on. Try looking past the subject when you are looking through the camera, and see if you can move a bit to find a cleaner background. It makes a huge difference.
