Zuffa has gone on a tear this week of picking up top Japanese talent, now with their third major signing, longtime ZST (for those wondering, it's "zest") standout Shunichi Shimizu. ZST is something of a strange, "hybrid" organization formerly holding tag-team, shoot, modified grappling, and alternate rules MMA bouts, however Shimizu has long been one of their most legitimate fighting talents. MMA in Asia announced his signing Friday. No debut date or potential opponent has been announced.
