Bianca Andreescu was left screaming in agony and had to be taken off court in a wheelchair after suffering a leg injury at the Miami Open. The 2019 US Open champion fell to the court, clutching her lower left leg while moving across the baseline during the third game of the second set of her fourth-round match against Ekaterina Alexandrova. Andreescu was left in tears, crying out “I've never felt this kind of pain before”, as she received medical treatment. The Canadian was eventually helped to her feet and shared a hug with Russian Alexandrova before leaving Hard Rock Stadium in a wheelchair to a standing ovation from the crowd. “I'm just really sorry that it happened,” said Alexandrova, who will now take on Petra Kvitova in the last eight. “Seeing her on the court in so much pain, it's just painful to watch. “You cannot help, you just can do nothing, which is terrible. And I think she's going to be fine soon, and I'm wishing for her speedy recovery.” Andreescu had dropped the first set 7-6 and was mounting a comeback, winning the first two games of the second set when she was forced to retire, allowing Alexandrova to advance.

To be in a quarter-final is great and hopefully I'm going to play better,” she said. World No 2 Aryna Sabalenka looked in ominous form as she powered past Barbora Krejcikova in straight sets. Krejcikova had ended Sabalenka's 13-match win streak in February in Dubai but Sabalenka defeated the Czech two weeks ago at Indian Wells. This time Sabalenka took just 65 minutes to take care of business, going unbroken in the match and facing just one break point on her way to a 6-3, 6-2 win.

Super happy with the level, especially against a player like Barbora, always tough matches against her.” Jessica Pegula looked comfortable and in command of her game as she beat Poland's Magda Linette 6-1, 7-5. The American goes on to face Russian Anastasia Potapova, who beat China's Qinwen Zheng 6-4, 7-6.
