Flash photography at a baseball park results in a nice photo of the back of the heads of the people sitting right in front of that photographer.

That is true if you are using a cheap camera.

It’d have to be a damn powerful flash to provide any light on Barry Bonds, the ball, or the pitcher.

Turn out all the lights in the stadium. Complete darkness. You think that any of that flash (even on a professional camera) is going to reach from the stands (let alone the upper decks in the outfield) to home plate?

You can open your aperture up as much as you’d like, it's not going to help.
