Fernandez faced 2017 US Open champion Sloane Stephens in the second round of the Abierto GNP Seguros. The in-form teenager was coming off a runner-up appearance in Acapulco, where she did not drop a set until the final.
Fernandez faced stiff opposition in Stephens, as the fifth-seeded American displayed some aggressive tennis to win the first set in a tiebreak. However, it was all Fernandez from that point onwards, who dominated the American to win the match 6-7(4) 6-3 6-3.
After this two hour encounter, Fernandez could face an even tougher test in World No.7 Elina Svitolina. The top seed battles Belarusian Olga Govortsova for a spot in the quarterfinals.
Sixth seed Rebecca Peterson defeated former Top-10 player Kateryna Bondarenko 7-6(2) 7-5 in just over two hours, while eighth seed Yafan Wang battled past Australian Astra Sharma 7-6(5) 4-6 6-3 to advance to the last eight.
Czech Marie Bouzkova made quick work of Anna Karolina Schmiedlova, who upset Venus Williams in the opening round. However, the ninth-seeded Czech was too much for Schmiedlova, breezing through 6-4 6-1 in just an hour and 22 minutes.
