Downs was recalled by the Red Sox on Saturday.
Downs made his big-league debut in late June but went 0-for-4 with three strikeouts in his lone game. He'll get another chance with Christian Arroyo (groin) landing on the 10-day injured list. Downs struggled early in the season for Triple-A Worcester but has been excellent in July, grabbing 13 hits in seven games while adding four homers and five steals.
