World number one Iga Swiatek overwhelmed another opponent with a rapid win as she cruised into the French Open third round.
Poland's Swiatek, 20, needed 61 minutes to win 6-0 6-2 against American Alison Riske at Roland Garros.
Swiatek, who beat Ukraine's Lesia Tsurenko in 54 minutes on Tuesday, has now won her past 30 matches and is aiming for a sixth successive title.
The 2020 Roland Garros champion will play Montenegro's Danka Kovinic next.
"I'm pretty happy. I'm playing solid tennis," said Swiatek, who has already won titles in Doha, Indian Wells, Miami, Stuttgart and Rome this year.
"I'm a perfectionist so I can still work on lots of things."
Swiatek has come into the clay-court Grand Slam as the biggest favourite for a women's major title in recent times following a stunning run in which she has dominated the WTA Tour.
The power and accuracy of her groundstrokes, particularly from the forehand, have proved difficult for anyone recently to cope with.
Riske, ranked 43rd, was the latest opponent to have few answers.
One of the hallmarks of Swiatek's success has been her ruthlessness and a 20-minute first set was the 15th bagel - a tour high - she had inflicted this year.
Seven points were all she allowed Riske and the dominance continued at the start of the second set.
After another ball flew past, the American simply shrugged at her box as if to say 'What can I do?'.
The unstoppable winners from Swiatek continued, although she showed she was human - hitting a volley into the net - to enable Riske to finally get on the board after 42 minutes.
A broad smile broke across Riske's face as the crowd on Court Suzanne Lenglen showed their support with a hearty round of applause.
That was about as fun as it got for Riske, with Swiatek going on to clinch a straightforward win which means she is only the fourth WTA player this century to win 30 matches in a row.
