Serena Williams joined sister Venus in the fourth round of the Australian Open after defeating compatriot Nicole Gibbs in the third round.
The world number two, chasing a 23rd Grand Slam singles title, won 6-1 6-3 in 63 minutes on Rod Laver Arena.
This is the 14th time in her 17 Australian Opens that the former world No 1 has made at least the last 16, and sets her up with a clash against 16th-seeded Czech Barbora Strycova, who beat French 21st seed Caroline Garcia, 6-2 7-5.
“She’s human, and she is beatable,” Strycova said of facing Williams in the last 16.
“This is a Grand Slam, and we are talking that she already won, but I don’t like these talks.”
Williams’ victory today marked the 35th time that both she and sister Venus have made the last 16 at Grand Slam level.
