Iga Swiatek

Iga Swiatek, who turned 21 on Tuesday, is on the longest unbeaten run in the women's tour since Serena Williams bagged 34 victories in succession in 2013.

The Polish player, gunning for a second title in three years at Roland Garros, appeared a tad shaky in the initial games before marching past the 11th seed to set up a meeting with Russian Daria Kasatkina for a place in Sunday's final.

The 2020 champion is bidding to become the fourth player since 2000 to lift the Suzanne Lenglen Cup multiple times after Justine Henin, Serena Williams and Maria Sharapova.

The Australian needed three match points before winning 6-1 7-5 on Arthur Ashe Stadium to pick up her 50th Grand Slam match victory.

The top seed raced through the first set but was unable to convert a match point at 5-3 in the second.

She was broken but responded to eventually serve out the match.

Barty will face American Shelby Rogers or Romanian Sorana Cirstea in the third round.

Swiatek, who had dropped only 23 games en route to the final, produced another audacious display as she became the first Polish player to win a Grand Slam singles title.

Only briefly in the first set did Swiatek show any weakness, letting slip a 3-0 lead, but having edged a tightly-contested opening set she romped to victory, although fourth seed Kenin's challenge appeared to be hampered by a thigh injury.
