needing help making a wrist joint more round rather than oval shaped...

Hello everyone.  I need help with something.  So i am working on making a doll with ball joints.  I am having trouble with the wrists, because they are more oval-like, which makes for a giant ball socket when trying to make the ball and socket joint for the wrist.  I really need to try to scale the wrist more so it is round rather than oval-shaped.  Any suggestions?  I've been beating my head against the wall on this one for days now.

thanks!
