6:22pm: The Nationals have interest in Darvish, writes Adam Kilgore of the Washington Post. GM Mike Rizzo didn't divulge whether the Nats plan to bid, but his refusal to comment suggests to Kilgore that they will.
4:50pm: Now that Darvish has been posted, teams will have until 4:00pm CST on December 14th (four business days) to submit bids, tweets Buster Olney.
12:40pm: The Yankees are unsure about whether they'll bid on Darvish, tweets Buster Olney. He considers their interest lukewarm. I think everyone's playing coy at this stage; we'll see where the bids were when the dust settles. By the way, Tigers GM Dave Dombrowski said this week he will not be bidding on Darvish, according to Jason Beck.
11:07am: The Dodgers won't be bidding on Darvish, tweets Dylan Hernandez of the L.A. Times, but A's assistant GM David Forst wouldn't rule it out in talking to Susan Slusser of the San Francisco Chronicle. Evan Grant of the Dallas Morning News hears the Rangers aren't willing to gamble $100MM on Darvish. The Red Sox will discuss Darvish but feel pretty good about the front end of their rotation already, GM Ben Cherington told reporters.
4:56am: Following the announcement last night that the Nippon-Ham Fighters will post ace Yu Darvish, Ken Rosenthal and Jon Paul Morosi of FOX Sports write that the Rangers, Blue Jays, and Yankees are all expected to bid on the Japanese righty. ESPN's Buster Olney also tweets that rival executives are expecting both the Rangers and Blue Jays to bid big Darvish, with the Rangers fueled by the expected loss of C.J. Wilson to the Angels or Marlins.
Rosenthal and Morosi write that the Red Sox could be a wild card for a big Darvish bid, as new manager Bobby Valentine, who saw Darvish first-hand many times as manager of the Chiba Lotte Marines from 2004-2009, is said to "love" the 25-year old. FOX's duo also note that both Blue Jays GM Alex Anthopoulos and Rangers GM Jon Daniels saw Darvish pitch in Japan last season.
The posting period will last four days, and the winning team will have a 30-day exclusive negotation period with Darvish and his representatives Don Nomura and Arn Tellem. If a contract agreement cannot be reached between Darvish and the winning team, that team will be refunded the total of the posting fee.
