Robinson went 0-for-3 with a walk and two strikeouts in Thursday's 5-1 loss to the Astros.
Robinson saw his at-bats pick up earlier in August when both Joey Gallo (concussion) and Carlos Gomez (back) were on the disabled list, but now that both players are healthy again, the rookie's window to regular starts has closed. It's still likely that Robinson, who can be deployed just about everywhere except pitcher and catcher, will pick up a start or two per week in September thanks to his versatility alone.
