But the Kent teenager has been plagued by injuries ever since – including blistering at the Australian Open. And she said after her latest injury worry: “It’s just one of those weird days where you feel a bit like nothing.” Raducanu first stopped her training with Russia’s Ekaterina Alexandrova after about 40 minutes. The 19-year-old was comforted by her trainer Dmitry Tursunov and her doctor Will Herbert. She was visibly in discomfort and was looking away from the small crowd that had gathered to watch her perform. Tursunov, who is being tested as Radukanou’s last coach, then sparred with Alexandrova until the world No 11 got back into the game. Five minutes later Raducanu ran off the pitch into the dressing room, followed by Herbert and her agent Chris Helliar. Raducanu’s compatriot, Britain’s Andy Murray, is backing her title defence. The two-time Wimbledon champion said: “I think she played really well last week. I watched a few of her matches. “I saw most of the match with Serena [Williams] and then her against Jessica Pegula,” Murray said. “Even though she lost that one, she’s playing a lot better. “The balls they use here help a lot, they’re a lot lighter, the women’s ball. That allows her to hit more shots, on her serves, she looks like she was enjoying the conditions last week. I imagine with It’s fast here in New York she’ll enjoy it. I expect him to play well next week.”
