Aryna Sabalenka rolled over an inexperienced opponent with her 6-0, 6-3 defeat of Maria Camila Osorio Serrano, first Colombian woman to reach third round here since 1973.
The second-seeded winner from Belarus added just five aces to her running total of 16 for the week and more than 200 on the season.
Wimbledon is only the second tournament on grass for Osoria Serrano, ranked a career-high 94th.
“It was a tough, tough first set,” the winner said. “The second set also.
“It was not an easy match against her, I’m happy to win and I’m looking forward to next week.”
Seventh-seeded former Roland Garros champion Iga Swiatek continued to make quick progress on the unfamiliar grass, crushing Romanian Irina Begu with the loss of just game.
The 57-minute rout featured seven double-faults from Begu while 2020 Paris winner Swiatek added to her grass total after winning just one match on the surface prior to this week.
The hammering denied Begu any chance at a Top 10 win since her last in 2018.
“I don’t want to put any expectation on myself. I’m just playing step by step, match by match, and not really focusing on what’s gonna happen,’ 2018 junior champion Swiatek said.
“It’s the good attitude towards the whole tournament.
“I’m playing better and better every match, and actually getting more confidence. I’m practising a lot during my free days.
“My grass skills are just better and it’s easier to adjust to any surface when you’re just a better tennis player. I grew up, so also mentally I can handle all the challenges.”
Eighth seed Karolina Pliskova beat Czech compatriot Tereza Martinkova 6-3, 6-3 over a player who had advanced past the second round of a major for only the second time.
“She had nothing to lose and she played a great match,” the winner said. “But I did well at the important moments.
“In close situations I played really good shots. I was super solid, serving well, and playing quite the game I wanted to play.”
Pliskova will next face surprise Berlin winner Liudmila Samsonova , who dispatched Sloane Stephens 6-2, 2-6, 6-4, reaching the second week of a Slam for the first time.
Victory was the 10th in a row for Italy based Russian Samsonova, ranked 65th and making her Wimbledon debut.
