The Pirates just announced a series of roster moves that shake up the bullpen a bit. Tony Watson has been placed on the paternity list and Rob Scahill was recalled to replace him. Arquimedes Caminero was placed on the 15-day DL with a left quadriceps strain, and Kyle Lobstein was called up from Indianapolis.
The Watson move is obviously only a short-term deal, and I'm guessing that Scahill goes back down when Watson returns, since the Pirates grouped the moves in that order. Also, Lobstein gives them a second left-hander once again.
I'll have more thoughts on the moves shortly.
