Cortes is out of the lineup for Sunday's game against the Astros.
Though he will hit the bench against southpaw Colton Gordon, Cortes could hold down the strong side of a platoon in right field until the Athletics get Denzel Clarke (adductor) back from the injured list. With Lawrence Butler shifting over to cover Clarke in center, Cortes started against right-handed pitchers in each of the first three games of the series in Houston, going 4-for-11 with three runs and one RBI.
