CHICAGO -- Shortstop Hanley Ramirez returned to the Los Angeles Dodgers' lineup Thursday after sitting out two games because of a strained right elbow, but the team's pitching plans remain unsettled for later this weekend.Pitcher Hyun-Jin Ryu, whose flight to Chicago was delayed, is scheduled to begin what the team is calling a "sub-maximal throwing program" on Friday. Veteran Dan Haren is scheduled to start Sunday against the Chicago Cubs, but the Dodgers could instead hold Haren back for Monday and use a combination of relievers to pitch Sunday's game, manager Don Mattingly reiterated.
