Express Action Sports

I started doing sports photography for the first time yesterday. I’m usually a landscape and architecture photographer, shooting things that generally don’t move a lot, so this was a real challenge to me.
The photos I took can be found here…

Can anyone offer me any constructive criticism or advice on things I could have done differently or better, so I can improve next week?
Thanks.

These are good for working with a point and shoot. I notice you were using aperture priority, try using shutter priority, also I notice you were using an iso of 100, for sports you want to use an iso that is a bit faster. I would start at iso 400. and set the camera on shutter priority and start at 1/250. For sports you really need an slr and a telephoto lens. You can get so much closer with a telephoto lens-This was taken from midway up in the stands.
