Interesting Color Change - Thoughts?

I was taking high ISO (6400) shots the other night at my son's baseball game, and was just now going through them. I found the following sequence of two consecutive shots interesting. No parameters were changed, and at most these are 1/3 of a second from one another, but notice how much different they look. All pertinent info shown in the screen capture.
