People.com Entertainment Sports Defending Champ Naomi Osaka, 21, Defeats Coco Gauff, 15, in U.S. Open Showdown Coco Gauff previously practiced with Naomi Osaka two years ago at the Miami Open By Karen Mizoguchi Published on August 31, 2019 08:25 PM Share Tweet Pin Email Photo: Tim Clayton/Getty Images; KENA BETANCUR/Getty Images Two tennis prodigies faced off in a tournament for the first time in a historic match. Naomi Osaka defeated Coco Gauff 6-3, 6-0 at the Arthur Ashe Stadium during the third round of the U.S. Open on Saturday evening. "I just want to say, 'You guys raised an amazing player. I remember seeing you guys training in the same place. I think Coco you're amazing,' " Osaka tearfully said to Gauff's parents in the stands. Osaka's stardom rose after defeating Serena Williams in last year's Open final. Meanwhile, Gauff, who became the youngest female to advance to the third round in the Open since Anna Kournikova in 1996, first burst onto the scene at Wimbledon when she defeated Venus Williams. Gauff previously practiced with Osaka two years ago at the Miami Open. "Obviously she's an amazing player. She's defending champion. She's won two slams. She's No. 1. She's only 21. We're both pretty young. But I'm a little bit newer to the game," Gauff said, according to ESPN. "I just want to enjoy it, have fun, enjoy the battle. We'll see how it goes." Tennis Star Coco Gauff, 15, Doesn't Feel Like She's 'Missing Out' on Being a Regular Teen The match was also on the radar of Williams, whom both Gauff and Osaka have looked up to. "I think it's super exciting tennis," she told Forbes. "Coco is obviously much, much younger than Naomi, if you could say that, because Naomi is incredibly young. But it's shocking to say that Coco is about six years younger." Williams, 37, added, "I definitely think it's the future of women's tennis. And I'm really excited to just be a fangirl and kind of watch."
