It seems Brent Leach's run with the Yokohama Bay Stars has come to an end. Leach returned to the US after the earthquakes and doesn't seem to be interested in returning to Japan at this point. It seems the Bay Stars may have already been prepared to lose Leach since pitching coach Atsushi Yoshida was quoted as saying, "I can't really say exactly, but he wasn't in our plans." The actual Japanese could be taken two ways: that the team knew from the start they weren't going to use him right away, or that the team knew he wasn't planning on returning. Either way, it seems he won't be returning.
Yokohama is planning on giving Takayuki Makka one last look on the 2nd (vs Hanshin Tigers @ Yokohama Stadium) to see if he can fill the spot left open by Leach.
UPDATE @ 9:51pm - Leach became the first ever Seigen Senshu (制限選手) today, which basically means a player with limited status (or a player on the restricted list). And that means he won't be able to sign with any teams unless he gets clearance from the NPB commissioner's office.
According to the Bay Stars, Leach seems to want to play in the Japan, but his family is apparently against him returning to Japan. The front office will leave the lines of communication open with Leach to see if something can be worked out.
And for those wondering about what the Bay Stars will owe him in terms of a salary, according to Section 60.2, the team can subtract 1/300th of his yearly salary for each day he misses.
UPDATE 4/2 @ 11:55pm - Nikkan Sports adds that Leach contacted the Bay Stars on the 31st to inform them that he couldn't return to Japan against his families' wishes and as such, couldn't set a firm return date. And Yokohama filed the Seigen Senshu paperwork because they feel he's worth protecting.
