Pirates Prospects reports that both Kyle McPherson and Justin Wilson will be with the Pirates in San Diego. It's not clear who will start tonight, but it might actually be Kevin Correia, in which case McPherson and/or Wilson might be needed to eat innings in the middle of the game, since Correia pitched two innings last night. It's also not yet clear how the Pirates will clear roster space.
Neither McPherson nor Wilson have pitched in the big leagues before.
UPDATE from David: We are expecting a bunch of moves to be announced by the Pirates in the next few hours and will use this post to keep things updated.
According to mlb.com transactions, Chad Qualls has been officially reinstated from the bereavement list. Jordy Mercer is not currently on the Pirates 25-man roster on their website, but I don't think his paternity leave has been officially announced.
UPDATE from Charlie: The Pirates have designated Juan Cruz for assignment and promoted McPherson and Wilson. Jordy Mercer has been placed on paternity leave. I believe the Bucs will have to make one more move to clear space before the game tonight. Kevin Correia will start tonight.
UPDATE from David: While the Qualls transaction is listed on mlb.com transactions, they Pirates have not yet announced it. I expect more moves and imagine they are testing Travis Snider to see if he needs to go on the DL.
UPDATE from David: I just heard from the Pirates that Chad Qualls will not be activated for tonight's game.
