Naomi Osaka's performance at the 2025 Miami Open has been a captivating blend of triumph and tribulation. While she's advanced to the Round of 16, showcasing a renewed fighting spirit and improved fitness, her journey hasn't been without its challenges. The four-time Grand Slam champion has openly admitted to feeling 'embarrassed' by her repeated racket-throwing incidents during her matches, revealing a vulnerability rarely seen from such a high-profile athlete. Osaka's run started with a hard-fought victory over Yuliia Starodubtseva, followed by dominant wins against Liudmila Samsonova and Hailey Baptiste. The match against Baptiste was particularly grueling, a three-set battle that pushed Osaka to her limits. It was this match that prompted her confession about her frustration, expressed in the form of several racket throws. While admitting this was not her best behavior, she also explained that her nerves were a significant factor, and that throwing her racket served as an outlet for releasing that tension. Despite this emotional outburst, Osaka's performance has been largely positive. Her movement on the court has been praised, and she's demonstrated a resilience and fighting spirit that has earned her a reputation as a tough opponent to overcome. She proudly notes that opponents now have to fight harder than ever to defeat her, a testament to her improved tenacity and determination. This improved fighting spirit and on-court resilience is directly linked to Osaka's remarkable fitness journey. Following a period hampered by injury and illness, including a retirement from the ASB Classic final and early exits at the Australian Open and Indian Wells, Osaka's comeback in Miami is a symbol of her dedication to physical conditioning. She states that her fitness level is currently the best it's been in years, exceeding even her 2021 form, a significant accomplishment given the setbacks she faced during the pandemic. The Miami Open has presented a crucial test of Osaka's fitness and mental fortitude. The length of her matches, particularly against Baptiste, has showcased her improved stamina and ability to persevere through challenging situations.
