While Naomi Osaka boasts one of the hardest serves in women’s tennis her success relies a lot on her mental game and her ability to cut down on her unforced errors and hit more accurately.  Although Osaka can serve with speeds up to 125 mph and return at speeds up to 100 mph she often uses a more patient, positive approach in each match to achieve her results. Osaka’s brand of choice for racquets has always been Yonex and more recently she has relied on the Yonex EZONE 98. This racquet accommodates Osaka’s game perfectly allowing a generous access to power, large sweet spot, and great feel. While using Yonex racquets Osaka has accumulated 264 total career singles victories and four grand slam titles. She captured her fourth consecutive grand slam title in the 2021 Australian Open defeating Jennifer Brady in the final. Osaka’s win in the 2021 Australian Open made her only the 3rd person in the Open era to win all of her first four Grand Slam finals along with Monica Seles and Roger Federer.

Osaka has autographed this Yonex EZONE 98 tennis racket the exact model she uses in silver paint pen. Her signature is deemed authentic by virtue of Upper Deck Authenticated's Five-Step Process.
