Japan's Naomi Osaka celebrates after winning against Slovakia's Anna Karolina Schmiedlova at the end of their women's singles first round match on day three of The Roland Garros 2019 French Open tennis tournament in Paris on May 28, 2019.
She was suffering with a hand injury coming into the tournament and looked like she was struggling throughout.
24-year-old Schmiedlova, ranked 90 in the world, by contrast looked in total control and she was dominant in the opening set.
