There are few knowns in the life of Ons Jabeur—even without the coronavirus mixing it up. The 26-year-old Tunisian tennis player went into England’s grass-court season earlier this summer unsure of how she might perform after months of tournament bubbles. She could hardly have predicted that she would emerge from the Viking Classic Birmingham with her first W.T.A. singles title and from Wimbledon Centre Court with a win over tennis icon Venus Williams.

But Jabeur had dreamed of—and practiced for—one definite: her post-match interview. She had been rehearsing it in her head for years, over dozens of grueling hours spent on the largely unnoticed backcourts of Grand Slams.
