My little brother scored 59 this weekend; by the time he was out his team was only on 69. There was no way I was going to go round to the other side of the oval each over but I still got some good shots even from behind him.
Both taken in shutter priority at 300mm for 1/1000s with ISO 800 then run through Neat Image.

F9.5 - I wish it had shallower DOF but the light was changing a lot so I stuck on ISO 800 which closed the aperture a bit.
EDIT: Have a look a bit lower down for a fixed up version with shallower DOF

F8 - just right :)
