Resizing a group to clip an object symetrically

I have a group that contains a single round graphic object. The group is narrower than the graphic so that only a segment of the disc is displayed. I now want to animate a reduction in the height of the group so that the disc is clipped symetrically at the top and the bottom. Setting the height or the rect of the group doesn't seem to work as the group only gets resized from the bottom. What am I missing?
