The second match of the morning at Príncipe Felipe was the most eagerly awaited moment for the local fans. It was the debut on centre court for Zaragoza's favourite twins, Majo and Mapi Sánchez Alayeto. They were up against one of the tour's legendary pairings: Carolina Navarro and Cecilia Reiter. It was the third time in three tournaments this seasons that they clashed. Just like in Alicante, the number ones started off strongly by breaking Carol and Ceci in the opening game. A warning of things to come as the players coached by Jorge Martínez took a 4-1 lead. Their brute power ripped through their opponents and helped them grab the first set 6-1 in 38 minutes.
The players coached by Vanesa Zamora tried to recover in the second set but the twins' total domination wasn't going to cease. They showed no cracks in their game as they went 3-0 up. They put in one of their best performances in a very long time to reach the semifinals of the Estrella Damm Zaragoza Open 2018 by winning 6-1 in just over an hour and 20 minutes.
