What they did not know - and what the Diamondbacks believe they had no way of knowing, according to sources - was that Abreu and the Dodgers were nearing a settlement on a grievance filed in 2007 that would award him extra days of service time and could make him arbitration eligible in 2011 instead of 2012. ....................................... It's unclear what action the Diamondbacks will take at this point, as Garland already has pitched for the Dodgers. Teams can file grievances with Major League Baseball over disputed trades. The sides agreed to a list of possible players to complete the deal, and the Diamondbacks could ask the Dodgers to amend the list in order to receive a player other than Abreu. Or the Diamondbacks could ask for cash to compensate for the difference in salary Abreu will earn during his arbitration seasons.
