The moves were largely necessitated by Moscot's injury Monday night. The right-hander separated his left shoulder in the first inning, forcing the Reds to rely on relievers Pedro Villarreal, Nate Adcock and Burke Badenhop for the remaining 7 1/3 innings.
The Reds simply needed to replenish their pitching depth.
"We're just a little beat up," manager Bryan Price said.
Price said Tuesday that the club will know the extent of Moscot's injury within the next 48 hours. Depending on the amount of damage to his shoulder, the rookie's season could be over.
