China's Olympic champion Zheng reaches Miami Open quarterfinals for first time

China's Zheng Qinwen reached the last eight of the Miami Open for first time with a 6-2, 7-6(3) victory over American Ashlyn Krueger on Monday.

Ninth-seed Zheng hit five aces and won 81 percent of her first-serve points as she took the match in an hour and 29 minutes. Krueger struggled for rhythm on serve, committing four double faults, while winning only 27% of total points on return.

Zheng's quarterfinal opponent in the WTA 1000 event will be top seed and World No. 1 Aryna Sabalenka, who advanced by beating defending champion Danielle Collins 6-4, 6-4 in their fourth round duel. Zheng, the reigning Olympic women's singles champion, is aiming for her sixth career title.

Meanwhile, third-seed Coco Gauff's bid ended with a 6-4, 6-4 loss to Poland's Magda Linette. Italy's Jasmine Paolini enjoyed a 3-6, 6-4, 6-4 comeback win over Naomi Osaka in 2 hours and 15 minutes.

Emma Raducanu continued her impressive form in Miami, cruising to a 6-1, 6-3 win in 69 minutes over American Amanda Anisimova, who had eliminated Indian Wells winner Mirra Andreeva on Sunday. It is the first time Raducanu has won four straight WTA Tour main draw matches since her US Open triumph in 2021.

Alexandra Eala, the 19-year-old from the Philippines who upset Australian Open champion Madison Keys on Sunday, was handed a place in the quarter-finals after her fourth round opponent, Spain's Paula Badosa, pulled out with a lower back injury.
