I guess from a personal standpoint you can Photoshop to your hearts content. If you ever want to shoot as a photojournalist, however, you will quickly find yourself out of work and blackballed if you Photoshop balls or other things into or out of place like you've done here.
And that takes me to my personal take on these things. This is a photography forum. We're all photographers to some degree...hobbyists, semi-pros, full-time pros...the whole gamut. I'd say post your best photography work here and if you want to make Photoshopping photos your thing, post those on other forums. To some degree, I can't help but think with images like the one here where you've moved the ball...what's the point? If it's a great sports image it will stand on its own without needing Photoshop.
Finally, I didn't really see the dodging/sharpening issues of the first pitcher image you posted, but they're glaringly obvious in the re-post. It's just way overdone. Again, let your photography speak for itself and stand on its own merit. Anyone can click a filter or feature in Photoshop. Not everyone can capture great sports action.
Hope that gives you something to think about. Good luck.
