Per Dylan Hernandez of the LA Times, the Dodgers cannot offer Manny Ramirez arbitration when he files for free agency, either after 2009 or 2010. This means the Dodgers will not receive draft pick compensation should Ramirez sign elsewhere. This is an unfortunate but expected side effect of Manny Fever.
Also, thanks to the Associated Press, we learn the date that Manny must decide whether or not to opt out of his 2010 salary is November 10, or the fifth day after the last game of the World Series, whichever is later. Game 7 of the 2009 World Series is scheduled for November 5.
