TUESDAY, 7:55pm: NPB Tracker's Patrick Newman tweets that we should know the high bidder by the 22nd or 23rd.
MONDAY, 8:26pm: The Chiba Lotte Marines are set to announce that they will post infielder Tsuyoshi Nishioka within the hour, reports FoxSports.com's Ken Rosenthal and Yahoo! Sports' Jeff Passan (Twitter links). Rosenthal notes that Nishioka will be represented by the Beverly Hills Sports Council while Passan speculates that the bidding could approach $15-20MM in a thin shortstop market.
Both the Giants and Dodgers have expressed interest in the 26-year-old switch-hitter, who hit .346 with 22 steals in 2010. ESPN's Keith Law (Insider req'd) described Nishioka as "valuable as an everyday guy on a second-division club," though he mentions that he struggles with good fastballs and doesn't offer much in the power department. NPB Tracker's Patrick Newman offered up his thoughts at FanGraphs recently, saying he sees Nishioka as a Ryan Theriot/Chone Figgins type.
