Belinda Bencic became the first player to book her spot in the fourth round of the Australian Open when she beat Kateryna Bondarenko 4-6, 6-2, 6-4.
Playing first up on the Rod Laver Arena, Bencic struggled to find her feet early on, but recovered from a set down to claim the victory in 110 minutes.
Bencic started well, breaking Bondarenko in the third game, but she soon found herself on the ropes when the Ukrainian broke back twice to take the opener 6-4.
The Swiss responded by securing a break in the opening game of the second set, and while the players then traded breaks, Bencic grabbed the decisive third break to go 5-2 up before serving out the set.
The decider was a much tighter affair, but Bencic claimed a break in the third game and was able to stave off the challenge of Bondarenko to book a fourth round encounter with Maria Sharapova.
Meanwhile, US Open runner-up Roberta Vinci became the latest seed to be knocked out after the Italian was beaten 0-6, 6-4, 6-4 by unheralded German Anna-Lena Friedsam.
The 13th-seeded swept her 21-year-old opponent aside in the first set – winning it to love inside 30 minutes.
The second set, though, proved to be a completely different affair. Friedsam raced to a 4-0 lead, two breaks of serve to the good. Vinci was able to pull one back but was unable to level and the match was sent into a decider.
The third set was the most evenly contested of the three, with both players losing serve twice in their first three service games.
Ultimately it was Friedsam who got the decisive break in the seventh game – when she broke the 32-year-old to love – and was able to serve out the remainder of the match to reach her maiden grand slam fourth round.
She will take on the winner of the match between Agnieszka Radwanska and Monica Puig for a place in the quarter-finals.
