Rubio and Arroyo, back together for a second time as a couple, bested six-seed Tello and Ruiz in three sets, the latter player being from the region of Malaga.
After reaching the final on home soil in 2022, Ruiz is left stranded in the second round in the current season while Rubio and Arroyo advance to the quarter-finals.
