Guzman is out of the lineup for Sunday's game against the Rangers.
Vaughn Grissom will draw the start at third base in place of Guzman, who covered the hot corner in the first two contests of the series. Despite handling a near-everyday role, the 22-year-old rookie hasn't provided much reason to get excited about his fantasy prospects with a .216/.245/.333 slash line to go with one home run, no steals, seven RBI and six runs through his first 19 games of August.
