Oh, galant try! You nearly got that ball in focus. You sure did a good job on getting detail on the kid. Good placement in the frame and great expression on the boy.
It's a bit 'hot' so you might try a little adjusting with "levels" and "curves" in Photoshop Elements or whatever editing program you prefer. Because this image can pop with just a little tinkering.
As a candid, it's okay to have all that background, and hey, you got the shot, but it's a good idea to position yourself so that the good shots come with a nice tidy background. (Just a thought) Another thought: think about blurring that background out a little, now that your image is out of competition. Because it's a keeper.
Meanwhile, I see you are new to DPC; this is your fourth Challenge. Welcome, and I hope to see lots more of your images.
Strike! Good composition and excellent timing, but the people in back are distracting, though it's very hard to eliminate that. Maybe if you could reduce DOF.
