19-year-old Bianca Andreescu has shocked the tennis world by defeating Serena Williams 6-3, 7-5 in the 2019 US Open Final, MySportDab reports.

Andreescu has become the first woman from Canada to win a Grand Slam after producing a stunning performance to beat Serena Williams in the US Open final.

Andreescu, playing in her first Major final, was gifted the ideal start after Williams double-faulted to drop serve and the 19-year-old was nerveless as she stayed in control and won the opening set 6-3.

In the second set, Andreescu’s level elevated even higher as she ruthlessly took advantage of a poor Williams serving day and served for the match at 5-2.

Williams hit back in stunning fashion to level the set at 5-5 but when serving to stay in the match, Andreescu found her form again and on her third championship, she cracked a forehand return for a winner to create history on Arthur Ashe Stadium.
