Japan Rumors: Nishioka, Kobayashi

The Chiba Lotte Marines will not decide whether to post shortstop Tsuyoshi Nishioka until after Saturday's championship game, tweets Jason Coskrey of the Japan Times.  Nishioka would prefer to play for the Dodgers if he's posted, reports Dylan Hernandez of the L.A. Times.  Otherwise, he hopes to land with the Giants, Padres, or Diamondbacks.  Of course, Nishioka can't control which team wins the bidding for the right to negotiate with him.  The 26-year-old switch-hitter batted .346/.423/.482 this year, and was described as a Chone Figgins/Ryan Theriot type by Patrick Newman of FanGraphs.  Hernandez says he'll be represented by Beverly Hills Sports Council if posted.

One Marines player is definitely heading to MLB, tweets Coskrey: free agent reliever Hiroyuki Kobayashi.  The 32-year-old righty reliever posted a 2.21 ERA, 7.82 K/9, 2.07 BB/9, and 0.30 HR/9 in 61 innings this year.  Kobayashi moved to the bullpen in 2010, reported Newman, so he brings versatility.  He will be represented by Octagon, MLBTR has learned.
