Top seed Iga Swiatek reached the US Open fourth round for the second time in her career after reeling off the final five games to beat Lauren Davis on Saturday.

The two-time French Open champion, who enjoyed a 37-match winning streak earlier this year, defeated Davis 6-3 6-4 in one hour and 57 minutes.

Swiatek had trailed 3-0 in the second lap but fought back emphatically to seal her passage into the last 16 where she will face either Jule Niemeier or Zheng Qinwen.

The attention in the women's singles has firmly turned to Swiatek, with Serena Williams eliminated along with the second, third and fourth seeds.

The Pole did not disappoint, hitting 25 winners and six aces, albeit with 38 unforced errors and an apparent lack of rhythm.

Swiatek wrapped up the first set in 59 minutes but world number 105 Davis offered a tougher test in the second after breaking in the second game.

The highly favoured Swiatek had to work out to avoid a 4-0 deficit, holding her serve in a 16-point game, but she showed she was back breaking Davis to love to make it 3-4.

Swiatek won 21 of the last 25 points of the match to book her spot in the second week in New York for the second straight year.

Data Slam: Swiatek finding her hard-court groove

The win improved Swiatek's 2022 tally to 53 matches but it also moved her a step closer to becoming the first player since Serena Williams in 2014 to win seven titles in a single year.

Swiatek has not quite reached the same dizzying levels lately since her 37-match winning streak, which was halted in the third round at Wimbledon, with this victory being only her fifth from eight during the hard-court season.
