Coco Gauff's five-week stay in Australia has been extended with a second-round win on Wednesday at the Adelaide International.

The 16-year-old American beat sixth-seeded Petra Martic 5-7, 6-3, 6-4 to advance to the quarterfinals of the hardcourt tournament at Memorial Drive.

Gauff lost to fifth-seeded Elina Svitolina in straight sets at the Australian Open. In 2020 during her Australian Open debut, she lost to eventual champion Sofia Kenin in three sets in the fourth round.

This year, Gauff also spent two weeks in COVID-19-forced quarantine ahead of the delayed Australian Open. She'll face fellow American Shelby Rogers on Thursday in the Adelaide quarterfinals.

In other matches on Wednesday, second-seeded Belinda Bencic also advanced with a 6-1, 6-3 win over Misaki Doi. Storm Sanders upset seventh-seeded Yulia Putintseva 6-4, 5-7, 6-1, Jil Teichmann beat eighth-seeded Wang Qiang 3-6, 6-3, 6-3 and Anastasija Sevastova defeated Christina McHale 6-4, 6-1.

The 23-year-old Bencic lost in the quarterfinals at Memorial Drive last year. She won six consecutive games from early in the first set to take control of the match.

"I really like this court, it’s only my second time here in Adelaide but I love this tournament, I feel very comfortable here," Bencic said in an on-court interview.

Top-ranked Ash Barty, who lost in the Australian Open quarterfinals, is the Adelaide defending champion. The Australian received a wild-card entry and plays American Danielle Collins in a second-round match later on Wednesday.
