The Reds have filed a grievance against the Washington Nationals over the trade that brought sore-shouldered reliever
to Cincinnati last season.
The Reds contend that Nationals general manager Jim Bowden failed to inform them of Majewski's shoulder problems when they got the righthander as part of an eight-player deal last July 13.
Bowden, a former Cincinnati GM, has said the Reds received all the information that they requested.
Reds rookie Josh Hamilton was treated at a hospital for a stomach problem and later released.
