She Knows How To Play Baseball

That's softball, actually.
And hitting homeruns in softball is pretty easy for anyone of reasonable fitness and basic hand/eye coordination.

In fact, even in relatively casual softball tournaments, teams regularly have to designate one or two "home run" hitters; they are the only ones that can hit home runs that score. Anyone else hitting a home run is OUT. And this is with pitchers deliberately trying to make them miss (unlike this video).
