2019 US Open Women's Singles Final Bianca Andreescu beats Serena Williams to win title Saturday Sep 07,2019

Teenager Bianca Andreescu stunned Serena Williams in a gripping US Open final to claim a first Grand Slam title and deny the American a 24th major.

Williams, 37, did not cope with the 19-year-old's quality in a 6-3 7-5 loss.

Canadian 15th seed Andreescu, in the main draw here for the first time, blew a double break in the second set before taking her third match point and falling to the ground in disbelief.

"This year has been a dream come true," Andreescu told the crowd.

"I am beyond grateful and truly blessed. I've worked really hard for this moment. To play on this stage against Serena - a true legend of the sport - is amazing."

Serena Williams seeded eighth, looked edgy throughout as she aimed to match Australian Margaret Court's tally of all-time major wins, handing over the first three of Andreescu's five breaks of serve with double faults.

By contrast, Andreescu played with the confidence which has marked her out as a star in a stunning breakthrough year.

She is the first Canadian to win a tennis major and the first teenager to win a Grand Slam since Maria Sharapova claimed the 2006 title at Flushing Meadows.

She is the first teenager to win their maiden Slam since Russian Sharapova at Wimbledon in 2004.
