Tim, here is another I worked on. I used DPP and brought the exposure up almost 2 stops, used the landscape picture style (one of my favs), pushed the shadow slider up a bit, strengthened the sharpening and set the WB as best I could.
I then edited in Photoshop for composition, noise reduction, and more USM. Here is your before and my after.
I think I would give the same advice. I would go to ISO 6400 and maybe 1/800th. The image wouldn't be quite as underexposed, and the motion will stop a bit better. I would also shoot a custom WB there at the game (unless you don't use DPP at all).
This makes me considered go back to DPP and GIMP (I know is not Photoshop, I am cheap
) combination... I been using DxO OpticPro 10 to clean high ISO and process my pictures for the last two years, or so...
