First baseman Pedro Alvarez and second baseman Neil Walker are both out of the Pirates' Sunday lineup.
Alvarez is replaced by Sean Rodriguez, who gets his second start of the year at first base. Rodriguez will hit sixth.
Walker's absence requires shifts at all other infield positions. Josh Harrison moves over from third place to replace Walker at second. Jung Ho Kang moves to third from shortstop, and Jordy Mercer returns to the lineup at short, for just the second time in eight games.
