Valdez is out of the lineup for Monday's game against the Orioles, Gabrielle Starr of the Boston Herald reports.
Valdez had started in three of the last four games but will take a seat against a left-hander. Romy Gonzalez draws the start at second base Monday. There had been speculation that Ceddanne Rafaela would move to the keystone with Trevor Story's return from the 60-day injured list Sunday, but that has not developed yet. It could, but early on with Story taking back over as the Red Sox's everyday shortstop, second base has been covered by Valdez against righties and Gonzalez against lefties.
