Born in Osaka, Japan, Naomi Osaka has made a name for herself in the tennis world largely due to her powerful serves.  In the 2016 US Open she delivered a serve at a whopping 125 mph, a speed which has been eclipsed by only 9 other women in WTA history.  While Osaka can hit serves at almost record speed it’s her concentration and focus which has made her one of the best in the game.  As she has gotten older, Osaka has shied away from the hardest serves stating “I only try and do those shots if I’m 100% sure it’ll go in”. It’s the art of the serve, the ability not just to hit the fastest serve but a serve that’s a little slower and more accurate that has led Naomi Osaka to tennis fame. The 24 year old four time grand slam Phenom knows the path to success isn’t just about power but also focus. Osaka’s has autographed this ‘Art of the Swing’ 36” x 15” image in black paint pen.
