After the sixth straight loss to the Mariners on Saturday the Reds sent Jumbo Diaz and Keyvius Sampson back to Louisville. They also designated Steve Delabar for assignment.
Diaz and Sampson just arrived from Louisville on Wednesday. Sampson pitched three innings on Thursday.
Delabar pitched a scoreless inning in his first appearance since walking four batters with the bases loaded on Tuesday.
Their replacements weren't announced.
"We have to make changes to be competitive. The bell tolls and we have to bring in guys who historically throw the ball over the plate and get ground balls. Diaz came off a nice run in Louisville but he came up here and had three appearances with multiple walks or multiple home runs. It's unfortunate that we are struggling to define roles and we don't have time to do that," Price said.
