No offense intended but this is a textbook example of a mediocre shot that could be very good with a blurred backround since the bacrkound doesn´t (in my humble opinion) add anything positve to the shot, only draws attention from the pitcher. On the plus side I like the composition although I would have preferred if you had taken a couple of steps to the left to get that building behind the pitcher out of the frame and you stopped the motion at a very interesting time. Gave it a 5 since it´s neiter bad nor good.
Great uniforms! What I don't care for in this image is are the background elements. If the DOF was more shallow, maybe they would have gone out of focus, lessening thier impact. 6
