World number one Iga Swiatek of Poland has crushed American Coco Gauff 6-1 6-3 to win the French Open women's singles title.

It was the second Grand Slam title for the 21-year-old Swiatek, who also triumphed at Roland Garros in 2020.

The victory on Court Philippe Chatrier against the 18-year-old Gauff — who was playing her first Grand Slam final — extended Swiatek's winning run to 35 matches.

Swiatek — seen as an overwhelming favourite before the start of the clay court major — broke Gauff's service five times over the two sets and sealed the contest on her first match point in an hour and eight minutes.

Swiatek's unbeaten run equals that of Venus Williams in 2000 as the longest this century.

Swiatek has now won her past six tournaments with a 42-3 record this year.

She has emerged as a dominant figure in tennis, with 23-time Grand Slam champion Serena Williams out of action for nearly a year and three-time major champ Ash Barty announcing in March she would retire at age 25 and relinquish the No 1 ranking.

That allowed Swiatek to move up to the top of the WTA rankings.

Her last loss came in February to 2017 Roland Garros champion Jelena Ostapenko.

Swiatek has a game that works on all surfaces, but her greatest triumphs have come on red clay.

Her 2020 victory in Paris made her the first player from Poland to win a Grand Slam singles title.

Rafael Nadal will face Casper Ruud in the men's final on Sunday.
