The reigning 19-year-old Roland Garros champion lost just 13 points in the entire match and will climb into the world top 10 for the first time after her landslide victory.
This is only the fourth time since 2000 that a WTA final has ended in a double bagel and is the shortest WTA final completed since Istanbul in 2009 when Vera Dushevina defeated Lucie Hradecka 6-0 6-1 in 41 minutes.
The ninth seed Pliskova, winner of the tournament in 2019, failed to win a match in a game that ended for the second time in his career. The 29-year-old Czech was playing her third straight final in Rome after retiring from last year’s final with a leg injury as she edged Simona Halep 6-0 2-1.
Swiatek, who saved two match points against Barbora Krejcikova in the third round, made just five unforced errors against Pliskova and struck 17 winners.
In contrast, Pliskova served two double faults in each of her first two service games and didn’t strike a winner until she was tune after 19 minutes.
Swiatek, who lost four points in the first set and nine in the second, faced just four match points against her as she recorded her third career title and first at a WTA 1000 event.
After winning the French Open at Roland Garros last fall, Swiatek also triumphed in Adelaide in February. PA Media
