Thanks for the comments

, Yes it is quite a difficult sport to shoot.
Also seems pretty dangerous, within the first 10 mins of the game two people were hit with a ball to the face.
stepheno I did up the ISO I think most of these were shot at ISO 800, so I could stop down to get more dof, although looking at them now I think I would of done better using lower ISO and larger apeture. Shutter speeds were around 1\400 - 1\500 and aperture between f/9-f/11.
They do seem a bit light whilst I am at work

, they seemed alright when I was editing them last night (could just be the dodgy lcd panel I have at work, never liked them for looking at pictures with).
