Coco Gauff has survived a huge scare to launch her US Open title quest with a titanic three-set victory over giant-killing Australian Ajla Tomljanovic.
Three years after ending Serena Williams' storied career under New York's bright lights, Tomljanovic threatened to pull off another major shock on Arthur Ashe Stadium after snatching the second set in a tiebreaker.
The three-time grand slam quarter-finalist had Gauff under immense pressure after breaking back for 5-5 in the deciding set, before the third-seeded 2023 champion responded.
