Pruitt (undisclosed) returned from the injured list at Triple-A Durham, allowing two runs on two hits and a walk while striking out one batter in one inning Wednesday.
His first appearance in 11 days was not pretty. Pruitt's ERA at Durham is now back over 6.00, and if he doesn't impress in subsequent outings, Pruitt could end up being a 40-man casualty around the trade deadline.
