four times the light... so if you have a shutter speed of 1/100 with f/5.6 you could have 1/400 at f/2.8... with sports thats the difference between getting a reasonable shot and getting a blurry mess.

As Jay said, it's hard to be specific about the problem you've had (can you upload the full sized versions unedited?), although it looks like a combination of:
High Iso - thus a grainy, low detail, low contrast image.
low shutter speed
poor focus
poor lens optics
Again, because I don't know the settings I can only offer some basic guidelines for sports:
Use a single point focus, rather than allowing the camera to choose where the camera focuses.
Use a continuous/tracking focus
follow the subject as you take a photo rather than holding the camera still i.e. panning.
This might be a bit too much but...With static images, most people use a rule of thumb regarding
minimum
shutter speed in order to get a sharp image.
The guide is:
shutter speed = 1/(chosen focal length * 1.6)
so if you have chosen a 100mm lens, then your shutter speed is:
shutter speed = 1/(
100 * 1.6) = 1/160
that 1/160 is the
minimum you should be shooting at... so if you're particularly shakey, then you might want 200, 250, 320 even.
Now depending on your chosen subjects and sports, you will need shutter speeds even higher 400, 500, 640 range minimum, to capture the image.
