The Pittsburgh Pirates announced the signing of Kevin Correia today, a week after they agreed to terms with the free agent right hander. The delay between the agreement and the signing was expected, due to Correia’s wife having a baby last week. Before Correia is added to the 40-man roster, a spot needs to be opened up, since the 40-man roster is currently full.
Jennifer Langosch mentions that a spot could be cleared either tonight or Monday, when the Correia signing becomes MLB official. If the Pirates are going to designate someone for assignment, my guess is that it would be Chris Leroux. Since they don’t have to remove anyone until Monday, it could be possible that they use the extra days to try and trade Ryan Doumit, which would also clear a roster spot (assuming they didn’t receive any 40-man roster additions in return).
