Swiss second seed Belinda Bencic and American Coco Gauff shrugged off disappointing Australian Open showings by advancing into the Adelaide International quarter-finals on Wednesday.
Bencic, who exited Melbourne in the third round,defeated Japanese lucky loser Misaki Doi 6-1, 6-3 in 74 minutes.
Teenaged qualifier Gauff made up for her second-round exit earlier this month by earning a 5-7, 6-3, 6-4 comeback over Croat sixth seed Petra Martic after two hours.
“I think I’ve just been taking it one match at a time, to be honest,” Gauff. aged 16, said. “I go into every tournament thinking that I can win.
“I try not to think far ahead in the match because you have to get through that before you can get to the finals.”
Gauff moved on to a quarter-final against compatriot Shelby Rogers, who knocked out Brit Johanna Konta in the previous round.
The 12th-ranked Bencic, who once reached fourth in the world, broke No. 86 Doi six times
“Misaki’s a very tricky opponent,” the winner said. “I had a good game plan, and I was trying to play really aggressive, stepping up with my game, not having fear, and definitely trying to build up my confidence here.”
Bencic was joined by Fed Cup teammate Jil Teichmann, a winner over China’s eighth seed Wang Qiang 3-6, 6-3, 6-3.
