"I think every loss is somewhat in my control because I do feel like I'm a good player, but today she just played better," Gauff, seeded seventh, told reporters.
"I think it's because I worked really hard and I felt really good coming into the tournament and I still feel good," Gauff said.
"But when you play a player like her and she plays really well, it's like there's nothing you can do.
"I think doubles has taught me how to play after losing, how to play with frustration," Gauff added.
I hope I can help her and I hope that she continues well in the (singles) tournament now that I'm out.
