MELBOURNE, Australia — There’s a young woman who looks a lot like Coco Gauff at Melbourne Park for the Australian Open. She has the same fiery, competitive eyes, the same tendency to break out in a giggle in the middle of a sentence and the same number of titles.

America's biggest tennis star had a bad summer in 2024. After she double faulted 19 times in an early exit in the U.S. Open, Gauff said she didn't want to lose a match like that again, then brought on a new coach and adopted a new grip to ensure it.
