Pirates acquired INF John McDonald from the Diamondbacks for a player to be named later. FOX Sports' Ken Rosenthal first reported the deal while CBS Sports' Jon Heyman passed along word about the player to be named later. McDonald, 38, batted .249/.295/.386 with six home runs in 213 plate appearances last season while making appearances at shortstop, second base and the hot corner. Known as a solid defender, he should be a useful bench player for Pittsburgh.
