Miami:Japan's Naomi Osaka delivered a composed and controlled performance to defeat Astra Sharma of Australia 6-3, 6-4 in the first round of the Miami Open, advancing in 1 hour and 20 minutes on Wednesday.
It was Osaka's 50th career WTA 1000 win, and sets up a second-round clash against another former World No.1, No.13 seed Angelique Kerber. Osaka claimed her first career Top 10 win over Kerber at the 2017 US Open, ending the German's title defence in the first round, but has lost all four of their subsequent matches.
Two weeks ago, Osaka had departed Indian Wells in tears after being rattled by a heckler during her 6-0, 6-4 second-round loss to Veronika Kudermetova. After her win over Sharma, she said she was keen to put that behind her.

"I didn't want to let anything bother me, no matter what happened," Osaka said. "The last match I played was not the greatest memory for me. I wanted to prove that I could come back out here and compete, and no matter if I won or lost, to just know that I had the best attitude I could."
