Finger Stretches!

To all pianist:

It is hard for me to reach intervals that are lager then a 9th, so I was wondering if they are exercises that i could practice to alleviate this.

I can't imagine that you're going to be able to pull this off, as the limitation is largely due to the span of the skeletal structure of your hand.  I mean, can you expand your hand to where your thumb and pinky are in a parallel line with each other?  And is this distance wide enough to plink out a 9th?  If not, there's nothing that's going to change that.
