Coriolis force.

So which way does a baseball rotate when it hits and leaves the bat? Does it rotate differently in each hemisphere?
And what about other batted (cricket) and thrown objects...does the Coriolus affect them in any way, or is it simply the centrifugal spin of contact? I know the spin of thrown objects is almost wholly influenced by the style of release, but are there any hemispheric factors at work in this?

And what about a boomerang...will it come back in an oppsite arc in the Northern hemisphere?
