Caroline Garcia is now three wins away from her first title of 2023 after defeating Nuria Parrizas-Diaz 6-3 6-2 in Thursday's second round of the Monterrey Open.

France's Garcia, the world number five and top overall seed, needed just 63 minutes to see off her Spanish challenger. She controlled the contest with her serve, taking the ace count eight to two while winning 75 per cent of her total service points (33-of-44).

She will now face Egypt's Mayar Sherif in the quarter-final after the seventh seed survived a tough 3-6 7-6 (8-6) 6-4 test from China's Wang Xinyu.

Fourth seed Elise Mertens emerged the 6-3 3-6 6-2 victor against Romania's Elena-Gabriela Ruse, while rising 22-year-old Italian Elisabetta Cocciaretto prevailed 7-6 (7-5) 7-6 (7-3) against Germany's Tatjana Maria.

North of the border in Austin's ATX Open, Danielle Collins ripped off a 67-minute 6-1 6-1 drubbing of Caty McNally to advance to the quarter-final.

Collins will meet Russia's Anna Kalinskaya next after the 24-year-old's convincing 6-3 6-1 victory over veteran CoCo Vandeweghe.

Eighth seed Marta Kostyuk is one of only three seeded competitors remaining after storming home in a 6-3 3-6 6-0 battle with Madison Brengle, and Germany's Anna-Lena Friedsam won the longest match of the day in a 7-5 6-7 (2-7) 7-6 (10-8) three-hour war of attrition against 18-year-old Russian Erika Andreeva.
