Matt Adams, whose solo home run provided all the offensive output in Friday’s victory, followed it up a night later. He sent the fifth pitch of the seventh inning over the fence in right field to give the Cardinals a one-run lead. Two insurance runs followed in the inning, and combined with another quality start from Shelby Miller, the Cards beat the Nationals, 4-1, on Saturday in front of 44,785 at Busch Stadium.
