Aranda was optioned to Triple-A Durham on Tuesday, Tricia Whitaker of Bally Sports Sun reports.
He was up with the Rays for two days while Josh Lowe was on the family medical emergency list, but he'll now head back to Durham with Lowe back in the fold. Aranda has crushed Triple-A pitching again this season, but it hasn't led to much of an opportunity in the majors.
