The Pirates were shut down on consecutive nights by Josh Johnson and Ricky Nolasco, mustering almost no offense in their past two games.
The Marlins' starter will be Chris Volstad, an enormous 6-foot-8 hurler who nonetheless isn't a power pitcher - his average fastball this year has been a little under 90 MPH. He allowed five runs in his last start, against the Braves, and has four strikeouts and six walks in two starts this season so far.
Andrew McCutchen, who missed Wednesday night's game because his father had been hospitalized, will rejoin the Pirates' lineup Thursday.
The Pirates will return home to begin a series against the Washington Nationals on Friday.
