Southpaw from the Far East

The Sox are going to announce officially this afternoon that they've signed Hideki Okajima. Reports are for a two or three year deal, probably at somewhere around $3 million a year. I haven't seen any translations or projections of how his very good strikeout numbers might be against MLB hitters, but I'm confident that this is far more than just a move to find a best friend and sake-drinking buddy for Matsuzaka...Do we have any numbers of how Matsui did against him back in Japan? That's a research project for me this weekend.
