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.
