Things were not going well for Coco Gauff against Emma Navarro at Centre Court, not well at all, and she kept looking at her guest box for help from her coaches. One, Brad Gilbert, would stand up and gesture, and they would talk back and forth, but a fix did not arrive.

Gauff has yet to make it past the fourth round at Wimbledon, and she exited at that stage again Sunday, eliminated by Navarro 6-4, 6-3 in an all-American matchup.
