The victory at the Australian Open seemed to have established the definite role of Naomi Osaka, as the new WTA Tour dominator. After the success at the US Open 2018, against Serena Williams, the passing of the baton could be the definitive one.
Then the Australian triumph was the certification of an assured winning career. Winning two Majors by the age of 21 brought the world no. 1 deserved success, and some notoriety. Her steel nature and her winning mentality were a business card that could have intimidated all her opponents.
After Melbourne, however, it was Osaka's performances that were intimidated. Objectively, she disappointed during winter-time, especially at Indian Wells and Miami. Despite tournaments on clay-courts are played on a surface on which she expresses her worst tennis, Osaka made the quarter-finals in Madrid and Rome, and semi-finals in Stuttgart.
At Roland Garros, it was worse, with the elimination in the third round. Her tennis seems to have lost its biting after Melbourne, especially from a physical and mental point of view, which were her two winning weapons, so far.
Managing fame and pressure at her age and after such important successes will not have been very simple. The grass swing can help Osaka find herself again. A surface to which her game can adapt but on which, she still has to prove everything.
However, she will have a great chance to be able to return to express her best tennis. Everything, in the end, will depend on the management of expectations and pressure, as the last two years of the WTA Tour have shown. In any case, she will start a very important time, on a playing surface on which she could be able to find confidence, determination and victories, despite the defeat in Birmingham second round against Yulia Putintseva.
