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.

The Astros finished off a sweep of the Dodgers with a 5-1 win at Chavez Ravine on Sunday afternoon. It was Houston’s first series sweep at Dodger Stadium since 2008.
