High School Softball

I went and shot a softball game last week at the high school where I teach.....I shot all these images from behind the fence with my 30d and a 70-200L 2.8is This was my first time shooting a sporting event and I really enjoyed myself.....can I please get a critique on these three images?

I think your pictures capture the emotion of the moment but imho I think you need to up your shutter speed quite a bit. If you are shooting at 2.8 and still have blur you should consider upping your ISO. I would also try to find a different angle to shoot the batter from as the door is distracting.
