Zimmermann expected to miss at least 1 start for Tigers (Yahoo Sports)

Jordan Zimmermann is expected to miss at least one start for Detroit, but Tigers manager Brad Ausmus says he's more optimistic now than he was Sunday, when the right-hander left his start in the sixth inning with a right groin strain. Ausmus said Monday that Zimmermann has a Grade 1 strain, which is the lowest level. Detroit has an off day Thursday, so the Tigers can skip Zimmermann's next turn without needing to add anybody to the rotation.
