rafking, you described two all-too-common common plays in girls' FP. I see them several times a week. They come in standing up when a slide would get them there quicker, and they collide with a fielder at a level below that of "crash." Often they even slow down—increasing their chances to be out—and collide at the "bump" level. (Your plays described the fielder being knocked down, so the contact was evidently more significant.)

I'll bet that in the first play you describe, the fielder stood upright with both feet planted directly on the base, not with one foot on the bag and her arms and body stretched out to catch the throw.

In my experience, although the runners often don't do what they should, the fielders practically invite a collision.
