Hey there,
I have a fairly new camera so I am still learning all the bells and whistles, so please bear with me..
However, I have been taking some pictures at my son's baseball games.
The still shots of him on the field look great. I am having trouble with action shots. When he is swinging the bat, the bat comes out very blurry.
Also, I took some of him jumping up to catch a ball and he is blurred.
I had the camera on Sports mode which is what the manual said to use for action shots. Any suggestions? he has a big game tonight and I would like to get this figured out.

My camera is a Canon EOS 40D and I am using a Canon 70-300 lens.
Thanks for the help.
