The Reds have filed a grievance against the Nationals over the trade that brought sore-shouldered reliever Gary Majewski to Cincinnati last season.

The Reds contend that Nationals GM Jim Bowden failed to inform them of Majewski's shoulder problems when they got the right-hander as part of an eight-player deal last July 13. Majewski has struggled since joining the Reds, and is in the minors this season.

MLB spokesman Patrick Courtney confirmed the grievance on Saturday. Baseball officials will gather information about the disputed deal, and could decide to let it stand or force the teams to amend it.
