The Reds confirmed they filed the grievance with Major League Baseball over the Gary Majewski trade.
Wayne Krivsky would not comment on it.
The crux of the case will come down to whether the Reds can prove that they were misled on Majewski's condition before the July 13 trade. The parties involved were deposed by the Reds lawyers.
Nationals GM Jim Bowden wouldn't comment on it either when asked about it by the Washington Post.
There's no deadline for a ruling. If the Reds win, it would put Bowden in a tough spot with the new ownership in Washington.
