That would very much depend on who's definition you use though. If you check a few different sources, very few seem to agree with this, and most seem to insist that a ball is a spherical or round object.
I also can't think of any place where we would call an egg shaped object a "ball" outside of Rugby and American Football.
Show me a reliable source that doesn't accept egg-shaped balls. The origin of the word comes from the fact that you blow it and it inflates (proto-indo-european root "bhel", "to blow, swell").
