Out of curiosity, how much do you Brits know about (to be somewhat equivalent) baseball?

I'm vaguely familiar with the rules (which AFAICT are much simpler than those of cricket), but, even armed with that knowledge, reports of baseball matches are completely impenetrable. Sports writing (sport squared, in Eco's term) seems to generate jargons entirely its own, above and beyond the jargons of actually playing the sports in question.
