Coco Gauff and Naomi Osaka face off Monday afternoon at 1:10 p.m. ET in the fourth round of the US Open, and their roles have decisively reversed since their last meeting in Queens.
Gauff’s first professional matchup with Osaka came at the 2019 US Open, when Gauff was a first-time participant at age 15 while Osaka was the reigning champion. The results were predictable. Osaka breezed past Gauff in straight sets, advancing to the fourth round.
However, just a few months later Gauff knocked off Osaka at the Australian Open, punching her ticket to the fourth round of a grand slam event for the first time in her young career. It was a sign of what was to come.
This time, Gauff has the target on her back. Now a two-time grand slam champion — including a US Open victory in 2023 –Gauff is the No. 3 seed in Flushing while Osaka is trying to climb her way back to prominence in the sport she once dominated.
