Robles isn't in the Mariners' lineup for Wednesday's game against the Dodgers due to a hip issue, Ryan Divish of The Seattle Times reports.
The Mariners haven't offered any information regarding the nature of Robles' injury or how long they expect the outfielder to be sidelined, though he'll have the benefit of an additional day off Thursday before Seattle's next series against the Giants. Luke Raley will start in center field Wednesday while Justin Turner covers first base.
