World No. 1 Iga Swiatek swept to a 6-2 7-6 (7-5) victory over Tunisia's Ons Jabeur in the U.S. Open final on Saturday to clinch her maiden trophy at Flushing Meadows and third Grand Slam crown.

Poland's Swiatek fell on her back and covered her face with her hands after prevailing in the tight second-set tiebreak, having sealed the win when fifth seed Jabeur's shot sailed long.

It was two-time French Open champion Swiatek's first Grand Slam title on a hard court as the 21-year-old became the first Polish woman to win the U.S. Open.
