Naomi Osaka

Naomi Osaka was born in Osaka to a Haitian father and a Japanese mother, raised in the United States from age three, and turned professional in 2013 without ever playing a junior tournament. She announced herself at 16, beating former US Open champion Samantha Stosur in her tour debut, and inside five years had grown into the most marketable name in the sport — and, for a stretch, the highest-paid female athlete in the world.

The game is built on first-strike tennis. One of the biggest serves in the women's draw sets up a flat, early-struck forehand engineered to end points in two or three shots, before a rally can take shape. It's high-risk, high-reward power that flattens opponents on a quick hard court and can wobble on slower clay, where the margins shrink and she has less natural time. When the serve is firing and the unforced-error count stays in check, few players on tour generate cheaper points.

Her résumé is hard-court royalty: four majors, all on the surface, split evenly between New York and Melbourne. She won the US Open in 2018 and 2020 and the Australian Open in 2019 and 2021, reaching world No. 1 along the way. The slam credentials are why every draw she enters carries a different gravity than her ranking alone suggests, and why a meeting with the likes of Coco Gauff or Iga Swiatek reads as marquee regardless of seeding.

Now ranked 15, Osaka is several seasons into a comeback after stepping away from the tour and returning from maternity leave, rebuilding her ranking and chasing the deep major runs that defined her peak. The serve-forehand blueprint remains intact; the project is stacking the consistent results that turn a dangerous floater back into a seed nobody wants to draw.
