Naomi Osaka and Coco Gauff are two of the brightest young stars in tennis today, and the evidence backs them up. All eyes were on the both of them when they faced off for the first time at the US Open in 2019, where Osaka beat Gauff in straight sets (6-3, 6-0). At this time Osaka had already made a name for herself having won the US Open in 2018, but Osaka decided to show the ultimate level of respect and invite Gauff to join her for the encore interview. The friendly rivalry continued next year as Gauff would face Osaka again, this time at the 2020 Australian Open where Gauff would get her revenge beating the defending Australian Open Champ in straight sets (6-3, 6-4), setting the tennis world off into “Cocomania”. This time around, Gauff would extend the kind gesture by giving Osaka a hug at midcourt after. The rivalry between these two will only continue to grow as they get older and inevitably win more titles and achieve more success, both these young stars are just getting started.
