Elise Mertens reached the fourth round of the Miami Open with a 6-2, 0-6, 6-2 win over 22nd seed Anett Kontaveit on Sunday. The 16th-seeded Belgian will play second seed Naomi Osaka for a place in the quarter-finals.
Earlier, Osaka advanced to the last-eight after receiving a walkover from her third-round opponent, Serbia’s Nina Stojanovic. Stojanovic was forced to withdraw from both singles and doubles with an injury to her right thigh. In a statement announcing her withdrawal, Stojanovic said, “I’m sorry I can’t continue my participation at the Miami Open due to my recent injury during my singles match.”
Meanwhile, 29th seed Jessica Pegula upset sixth seed Karolina Pliskova 6-1, 4-6, 6-4. In their third meeting this year, Pegula cruised to a 6-1 4-1 lead before Pliskova found her bearings and won the next five games in a row to take the second set and send the match into the decider. It was also the first time that the Czech had taken a set off the American, who had won their previous two encounters in a ruthlessly straightforward manner. However, in the deciding set, Pegula once again asserted herself as she clinched the win after two hours and nine minutes of play.
In the pre-quarter-finals, Pegula will face 23rd Maria Sakkari, who dropped just one game en route to a 67-minute win over Russian qualifier Liudmila Samsonova.
Miami Open: Garbine Muguruza’s unrelenting stride
Two Spaniards completed the round-of-16 line-up in the bottom half of the Miami Open.
Sara Sorribes Tormo upset 30th seed Elena Rybakina 6-1, 3-6, 6-2 in their third-round match. She will play 27th seed Ons Jabeur for a place in the quarters. The Tunisian upset fourth seed Sofia Kenin 6-4, 4-6, 6-4.
Garbine Muguruza, seeded 12th in the Miami Open draw, will look for a place in the last-eight after taking a hard-fought win over Anna Kalinskaya. Muguruza went down a set to the Russian wildcard and was also down 0-3 in the deciding set before claiming a 4-6, 6-3, 6-4 victory after two hours and 41 minutes of play. In the fourth round, Muguruza will play Bianca Andreescu. The eighth-seeded Canadian defeated 28th seed Amanda Anisimova 7-6(4), 6-7(2), 6-4 in the third round.
