The slumping Los Angeles Dodgers are poised to get a big boost in the lineup. The defending National League champions, just 16-22 entering Saturday, are expected to see the return of third baseman Justin Turner and infielder Logan Forsythe from the disabled list Tuesday, manager Dave Roberts told reporters Saturday. Turner, 33, suffered a small non-displaced fracture of his left wrist when hit by a pitch in a spring training game and has not played yet this season.
