Expect Evan Longoria and Mac Williamson to return to the Giants' lineup for Saturday's 9:05 a.m. PT rematch with the Nationals. Manager Bruce Bochy figured that infusing the lineup with fresh personnel would be a good idea, with a day game following a night game. Right-hander Dereck Rodriguez is scheduled to make his third big league appearance and second start. The Nationals will counter with left-hander Gio Gonzalez, who's 5-5 with a 3.12 ERA.
