Can you think of another player whose first 2 career titles were of this caliber? I can't think of another of the top of my head. Osaka had never even won an ITF title in her career.So the 4 grand slam champions this year have been Wozniacki, Halep, Kerber and Osaka. I'm pretty neutral towards those first 3 players, but I was very happy to see Wozniacki and Halep finally crossing the finishing line and winning their first majors (this year's women's AO tournament was incredible), and for Kerber to win another major at a 3rd different venue no less to show that 2016 wasn't a flash in the pan.
And I've become an Osaka fan since I saw her play Venus at Wimbledon and beat Kerber at the US Open last year, so I'm delighted with her success. She my favourite WTA player alongside Caroline Garcia. She was cool and calm under pressure, served very well and expertly transitioned between attack and defence from the baseline. She beat the in-form Sabalenka in the 4th round before her convincing victories over Keys and Serena in the semis and final; an impressive way to win a first grand slam title.
