The Pirates have acquired lefty Steven Brault from the Orioles, the Pirates announced. He will serve as the player to be named later from this January’s Travis Snider deal, joining another young lefty — Stephen Tarpley — to make up the final package for Pittsburgh.

Brault, 22, was floated as a possible name to change hands at the time of the deal, and will indeed be on the move. The southpaw has worked primarily as a starter, reaching the High-A level at the tail end of 2014. He spent most of the year in the Sally League, compiling a 3.05 ERA with 8.0 K/9 against 1.9 BB/9.

Prospect watchers generally saw Brault as something like the twentieth-best prospect in the O’s system. Kiley McDaniel of Fangraphs explains that the southpaw will need to find consistent arm speed to reach the bigs as a back-of-the-rotation starter
