Trumbo (back) is out of the lineup Monday against the Giants, Shannon Drayer of ESPN 710 AM in Seattle reports. Trumbo was a late scratch from Sunday's lineup due to back spasms, and he may still be bothered by the issue Monday, though the team is yet to provide an update. With no DH in San Francisco, Trumbo will have to play the field if he's going to return during the team's current series.
