Teen stars Iga Swiatek and Coco Gauff earned Adelaide International victories on Tuesday, but third seed Johanna Konta is out.
French Open champion Swiatek secured a 6-3 6-4 triumph over Madison Brengle to set up a last-16 tie against home favourite Maddison Inglis, who beat veteran Sam Stosur in a three-set epic.
"Inside I'm the same person, but I realise that everybody's kind of treating me differently," Swiatek said after the win, as she reflected on the attention she now receives as a grand slam champion.
"So it's something you have to adjust to, and also keep yourself down to earth and the same as you were.
"We did a great job last year and hopefully this season will also be successful.
"Tennis-wise it also changes - I’m not an underdog anymore, so I start my matches with a different attitude, and that’s the kind of thing you have to learn to do.
"Madison is the kind of player who uses her opponent's power, so I had to stay cool.
"I tried to calm myself down, stay low in the legs, and sometimes play longer rallies to get in the rhythm, because the first round is always tough at any tournament."
Gauff also progressed, saving eight of the 11 break points she faced to defeat Jasmine Paolini 6-4 6-7 (4-7) 6-2 in a match lasting over two-and-a-half hours.
A tough test against Petra Matric is up next for Gauff in the last 16 after the Croatian sixth seed recovered from a set down to win against qualifier Ludmilla Samsonova.
Gauff's fellow American Shelby Rogers is the first player to reach the quarter-finals.
Konta had a bye in the opening round and had no answers for Rogers as she played her first match of the WTA 500 tournament.
Rogers won 6-2 6-2 in just 76 minutes, never dropping serve in the contest.
Rybakina moves past Mertens and into French Open fourth round
Elena Rybakina is through to the second week at the French Open, following another straight-sets victory over Elise Mertens.
The fourth seed wrapped up a 6-4 6-2 win in 67 minutes on Court Philippe-Chatrier, to book a last-16 clash with either Elina Svitolina or Ana Bogdan.
Rybakina was forced to withdraw injured on the eve of her third-round showdown with Sara Sorribes Tormo at Roland-Garros 12 months ago.
A tight opening set ensued with four successive games from 2-2 going against the serve, but a crucial break to love in the 10th saw the former Wimbledon champion draw first blood.
She then broke to 15 in game four of the second set to take control of the match, before another in the eighth saw her into the fourth round in Paris for a second time.
Rybakina is joined in the last 16 by home favourite Varvara Gracheva, who continued her groundbreaking run with a straight-sets win over Irina-Camelia Begu.
The Moscow-born 23-year-old, who obtained French nationality last June, is into round four for the first time at a major.
Extending her stay into the second week, having stunned sixth seed Maria Sakkari in the opening round, Gracheva was serenaded with Les Marseillais by the crowd following her victory on Court Suzanne-Lenglen.
Data Debrief: Rybakina matches Swiatek and Jabeur
Rybakina becomes only the third player to reach the fourth round at multiple majors on clay and grass since the start of the 2020 season.
The 2022 Wimbledon champion joins an exclusive group of players to achieve the feat, along with Iga Swiatek and Ons Jabeur.
Andy Murray revealed he may play alongside brother Jamie in the men's doubles at Wimbledon, with the pair to make a decision "in the next few days".
Murray and Dan Evans fell at the first hurdle of the men's doubles at the French Open on Friday, as the British duo were defeated 7-6 (8-6) and 7-6 (7-3) by Thiago Seyboth Wild and Sebastian Baez.
It was expected to be the three-time grand slam singles champion's final appearance at Roland-Garros, after he revealed in February that he does not "plan on playing much past this summer".
Murray, who was beaten by Stan Wawrinka in the opening round of the men's singles, now turns his attention to the grass-court season, which "may" include a familiar partnership at Wimbledon with brother Jamie - a two-time mixed doubles champion at SW19.
The brothers have also played together at two Olympics - in 2008 and 2016 - while their prolific partnership helped inspire Great Britain to Davis Cup glory in 2015.
"My brother doesn't have a partner for Wimbledon currently," said the 37-year-old, who last played in the men's doubles at SW19 five years ago alongside Pierre-Hugues Herbert.
"We have spoken a little bit about it. So I may do that, but not 100 per cent sure yet. [We will decide] ahead of time. Obviously, Jamie could also get a good partner, as well. We'll see what happens, but we'll probably decide in the next few days."
Murray also reflected on his and Evans' first-round exit at Roland-Garros, where he felt his progress was hampered by an ongoing back problem.
"It's been frustrating for everyone," he added. "I felt like we had a good chance to do well, and we agreed if we were going to play, we would play to try and win the tournament.
"I have been struggling a little bit with my back the last couple of weeks, so I probably needed a few lighter days anyway."
Mexico 1-0 Bolivia: Experimental El Tri boost Copa America preparations with narrow win
A youthful Mexico stepped up their Copa America preparations with a narrow 1-0 victory over Bolivia in Chicago.
Efrain Alvarez's second-half strike proved enough for El Tri, who fielded eight debutants at Soldier Field.
Two of those debutants went close early on; Ricardo Monreal heading against the bar and Ettson Ayon testing Bolivia goalkeeper Carlos Lampe, while Ramiro Vaca fired over for the visitors later in the half.
However, the hosts did find the breakthrough within two minutes of the restart, as Monreal squared for Alvarez to control and finish.
El Tri, who will face Ecuador, Jamaica and Venezuela in Group B at the Copa America, will play Uruguay and Brazil before the tournament begins on June 20.
Data Debrief: Mexico maintain Bolivia dominance
Mexico are now unbeaten in each of their last 10 meetings with Bolivia, winning nine and conceding just two goals during that span.
A 3-1 reverse at the 1997 Copa America represents El Tri's only defeat in this fixture.
