I wish Crunchroll would stream it, but at least I got them to put up a page on it in their library for discussion etc. :) http://www.crunchyroll.com/library/Cross_Game
So far Adachi's only officially English translated works have been two volumes of his short-story manga anthology, "Short Program." I have a bunch of his manga in Japanese, and would gladly buy it in English too. His characters are likable and pretty realistic, though his character design is pretty far from realistic. :)
Happy Friday.
