The Cardinals are placing right-hander Jack Flaherty back on the 10-day injured list, manager Mike Shildt announced to reporters during today’s pregame session (Twitter link via Jeff Jones of the Belleville News-Democrat). Flaherty, who only just returned from a two-month absence due to a severe oblique strain, has now been diagnosed with a strain in his right shoulder. Shildt indicated that imaging was “mostly negative,” suggesting that there’s no major structural issue in the shoulder.
