Novak Djokovic is on his worst losing streak since 2007.

“I always knew that she can produce a great game,” Svitolina said regarding Osaka. “All the times we played, we played quite a bit now…I think I was playing pretty solid today, serving good. This was the key for today. Making it physical, as well.”

Roge Federer credits his switch to a bigger racquet for his run of success the last few years.

Seeds including Novak Djokovic and Juan Martin del Potro begin play Friday in Miami.

“I cannot tell you much about this match, because I don’t really know how it is,” said Halep, who trailed by a set and 2-4 down. “I felt just that I played bad, but it’s a good day at the office and I’ll take it. You have these days, and when you don’t give up, it’s the most important thing.”
