Earlier in the year, the two faced off in the first round of Miami Open, where Osaka thrashed Serena 6-3, 6-2.Of course, Saturday was a completely different prospect with Serena’s fitness and power much better than March, when she was still feeding her daughter Alexis Olympia Ohanian.advertisementThis was an inter-generational battle where the 16-year age gap between Osaka and Serena was the second biggest in a major final in the Open era, topped only by the United States Open in 1991, where the 17-year-old Monica Seles defeated 34-year-old Martina Navratilova.After her semi-final victory over Madison Keys that made her the first Japanese woman in Open era to reach a Grand Slam final, Osaka had said ‘I love you’ when she was asked for a message for her idol. Everyone on the court had chuckled at her genuinity and Osaka had buried her face in her palms in embarrassment.On Saturday, however, Osaka showed no such naivity. She was up to the task and banged her powerful groundstrokes at Serena to completely unsettle the biggest female tennis star.Many experts have said that Osaka’s powerful groundstrokes is reminiscent of Serena and perhaps it was a taste of her own medicine for the 23-time Grand Slam champion, who was looking to equal Margaret Court’s 24-slam record in tennis history.The Pride of [email protected]_Osaka_ defeats Serena Williams 6-2, 6-4 to become the first Japanese player to win a Grand Slam singles title!#USOpen pic.twitter.com/sNilrZOaNUUS Open Tennis (@usopen) September 8, 2018Osaka took control of the match right from the start and in just the third game, she broke Serena to take a 3-1 lead in the first set.
