The 21-year-old German looked to be on the brink of another disappointing early exit from a Grand Slam, with 26th seed Dzumhur serving for the match at 5-4 in the fourth set.

Buzarnescu, seeded 31, has capped a remarkable rise from an injury-bedeviled ranking of World number 377 just 12 months ago.
“I didn’t know much about her because she raised really quickly,” Svitolina told reporters.
“I watched little bit video of her playing, so I knew a little bit what to expect. But today I was off and couldn’t find my rhythm, my game today, and was really struggling.
“On the other hand, she was playing great tennis. She was really, really on the ball today. I couldn’t do much today to get a win.”

“I mean, unfortunately I have to continually stop here, I mean, the same time. Paris has always been, I guess, great to me, but I just could never turn it around out here.”

“Clay is growing on me. It’s not my favourite still but being in the round of 16 for a second time definitely makes it a little bit better.”
