Bianca Andreescu has shocked Serena Williams to win the US Open.
The 19-year-old Canadian won 6-3, 7-5 to deny the American a record-equalling 24th major title.
It's Andreescu's first ever Grand Slam win.
She also becomes the first Canadian to win a tennis major and the first teenager to win a Grand Slam since Maria Sharapova claimed the US Open in 2006.
