Athletics' Robbie Grossman: On bench for afternoon game

Grossman is not starting the first of Saturday's two games against Seattle.

As usual, Grossman hits the bench with a lefty (Justus Sheffield) on the mound for the opposition. He'll presumably return to the lineup for the nightcap, with righty Justin Dunn scheduled to pitch for the Mariners. Mark Canha will be the left fielder in his absence.
