Canada's Bianca Andreescu has not tasted defeat in a long time.

The world No. 6 beat Elise Mertens of Belgium 6-3, 7-6 (5) today in a second-round match at the China Open in Beijing, running her unbeaten streak to 16 matches.

"Today was more of a battle mentally with myself than anything," said the 19-year-old from Mississauga, Ont. "I felt like I was getting very down on myself. I expect a lot from myself in general, but I have to realize not everything is going to go the way I want it to."

Andreescu fought back from a 4-1 deficit in the second set and then fended off a set point to beat Mertens in a rematch of a U.S. Open quarter-final. The Canadian also won in New York last month en route to her first career Grand Slam title.

"I can improve on a lot of things, but I think the main thing right now is definitely keeping a more positive approach to things," Andreescu said. "Even if there are 100 positives in something, if there is one negative thing that happens, that triggers something in me and I then I totally forget about all the positives.

"I just want to think of the positive as much as I can and just work with what I have."

There was some confusion about how many matches Andreescu had won in a row prior to Wednesday.

The WTA Tour clarified afterward her win streak stands at 16 matches because a walkover win for Sofia Kenin in the second round at the French Open does not count as a defeat for Andreescu.

Therefore, her last official defeat was in late March when she retired in the round of 16 at the Miami Open while trailing 6-1, 2-0 against Anett Kontaveit.

Jennifer Brady next for Andreescu

Andreescu will face world No. 66 Jennifer Brady of the U.S. on Thursday in the round of 16 at the $8.285 million US WTA Tour Premier-Mandatory event.

Andreescu has won three of four matches against Brady, all played at smaller tournaments.

"I'm not expecting anything easy because every time I did play her, it was a tough battle," Andreescu said.

Andreescu said she also needs to improve on her serve. She had seven double faults against Mertens and put just 53 per cent of her first serves in.

The Canadian saved eight of 12 break-point chances for Mertens to limit the problems caused by her serve. Andreescu also converted on five of her six break-point opportunities.

In women's doubles on Wednesday, the fourth-seeded team of Gabriela Dabrowski of Ottawa and Yifan Xu of China lost 7-5, 6-3 to Czech twin sisters Karolina and Kristyna Pliskova.

On the men's side, Andy Murray won consecutive singles matches for the first time since undergoing hip surgery in January.

The 32-year-old Murray beat British countryman Cameron Norrie 7-6 (6), 6-7 (4), 6-1 to make the singles quarter-finals at a tournament for the first time in 12 months.
