Sun, a New Zealander, defeated Raducanu in three sets on Center Court, winning 6-2, 5-7, 6-2.
The third-ranked player from Britain was hoping to make it to the Wimbledon women’s singles quarterfinals for the first time. She had to take a medical time-out early in the decisive set after tripping on the grass.
Due to wrist pain, the 21-year-old withdrew from her mixed doubles match against Sir Andy Murray on Saturday, denying him the opportunity to play another match at his farewell Wimbledon.
Many criticized the former US Open champion, with Judy Murray calling the choice “astonishing” before stating it.
Raducanu dismissed the intervention with a dismissive “I’m sure she didn’t mean it.”
She stated that accepting the offer was not a mistake, stating: “I was feeling good until I woke up stiff yesterday morning. My priorities need to be my body, my single status, and myself.
“I believe that was the appropriate choice. I maintain my position on the choice. It’s evident that choosing to pursue this goal has been difficult for me, though.
