Naomi Osaka advanced to the quarterfinals of Wimbledon after defeating world No. 1 Aryna Sabalenka in straight sets, 6:2, 7:6(2). This result follows a wave of upsets at the tournament, which saw top contenders Iga Świątek, Jelena Rybakina, and Amanda Anisimova exit the competition earlier in the week. Osaka’s victory marks a resurgence in her grass-court performance, which she credits to her coaching team, specifically Tomasz Wiktorowski.
How Naomi Osaka’s Coaching Change Impacted Her Grass-Court Performance
Following her victory over Sabalenka, Osaka publicly acknowledged the influence of her current coaching staff. When asked about her recent improvements on grass, Osaka credited “that big Polish guy,” referring to coach Tomasz Wiktorowski. According to reports from SportoweFakty, Wiktorowski responded to the praise by standing up and waving to both his player and the crowd.
The transition in Osaka’s form highlights the significance of team dynamics in elite tennis. Osaka described her team as the “best in the world,” emphasizing that the learning process and collaborative environment have been vital to her recent success on the court. Her ability to dismantle the world No. 1 suggests that this coaching partnership is yielding immediate tactical benefits in high-pressure situations.
Naomi Osaka’s win over Aryna Sabalenka is one of several high-profile upsets at this year’s Wimbledon, signaling a shift in the tournament’s hierarchy as top-ranked players exited early.
What Is Next for Naomi Osaka in the Tournament?
With the departure of several top seeds, Osaka has emerged as a primary contender for the title. Her path to the semifinals requires a victory over Karolina Muchova. Muchova secured her spot in the quarterfinals after a demanding three-set match against Barbora Krejcikova.

Comparing the current bracket to the start of the tournament shows a significant shift. While Sabalenka entered as the world No. 1 and a heavy favorite, the field has opened up following the exits of Świątek and Rybakina. Osaka’s performance against Sabalenka—specifically her ability to close out the second set in a tiebreak—demonstrates a level of composure that will be necessary to navigate the remaining rounds.
