Townsend had played doubles earlier and was receiving a massage when a message came in informing her that she was also going to play singles.

“It was crazy because I was in the trainer’s room getting a massage. I felt good and relaxed. I had already taken a shower and changed my clothes,” Townsend said. “You never know what might happen. It’s about always being ready. »
