Oh, I do have my share of similar pictures (not as crisp and sharp as yours, mind you). I guess it's in their education: They're told, "That's why we're call 'ducks'. When you see a camera pointed your way, duck..."
Not to bad...looks like a split fingered fast ball in the works here. I bet you had a blast. Being at a major league game is an experience all in itself.
It was great! Went with my nieces, so hot dogs, popcorn and cotton candy all around!
