Without a drop of rain, the Cardinals cruised to an 8-0 victory against the visiting Giants in the first game of today’s doubleheader. Shelby Miller got the win for the Cardinals, going seven innings, giving up six hits and striking out seven against the defending champs, who led the NL in hitting with a .270 average coming in to the game. On the offensive side, the Cardinals’ feasted off of Giants’ ace Matt Cain. This is nothing new. Before today’s start, Cain had a career 2-4 record and 6.18 ERA against St. Louis, and added to those abysmal numbers in the third inning. The Cardinals exploded for seven runs on seven singles and two doubles in the inning. Tony Cruz, who got the start behind the plate, highlighted the inning with a double that scored two, and Daniel Descalso and Pete Kozma both had two hits in the inning. The birds added one more run in the eighth inning, after a Matt Adams walk, Cruz double, and Descalso sacrifice fly that scored Adams pushed the lead to 8-0. To close out the game, Keith Butler, who was called up yesterday from AA Springfield, made his major league debut in the ninth. He walked his first batter, struck out one, and gave up one hit.
