The final of the women's Arroyo de la Encomienda Challenger 2018 was finally upon us. The favourites Carolina Navarro and Cecilia Reiter took on first time finalists Delfina Brea and Ana Catarina Nogueira. Brea and Nogueira didn't take long to pose problems for their opponents and a spectacular start saw them claim two breaks to open up a 4-0 lead. Reiter and Navarro set about turning the set around and got it back for 4-2 but it was just a minor spark. The set ended 6-2 with a world class drop shot from Delfina Brea. Cecilia Reiter required a medical timeout in the first set for a niggling injury and she never managed to shake it off. The Argentine decided to call it a day at the end of the set and conceded the final to Delfina Brea and Ana Catarina Nogueira. Their first title as a pairing and young Brea's first as a professional.
