Los Angeles Dodgers manager Dave Roberts could do little to counteract Houston Astros left-handers Bennett Sousa and Bryan King in the seventh and eighth innings of Sunday's 5-1 loss. Three of Roberts' four right-handed hitting reserves — Teoscar Hernández, Kiké Hernández and switch-hitter Tommy Edman — were unavailable because of minor injuries, which could force the Dodgers to make a roster move to bolster their bench depth before Monday night's series opener at Milwaukee.
