Canadian Bianca Andreescu made history in the Women’s Singles Finals of the US Open when she stopped Serena Williams from winning a record of seventh US Open Championship.

Bianca who was only having her fourth slam appearance won the US Open on Saturday against all odds when she beat six-time champion Serena Williams.

The Canadian stunned Serena Williams—and the packed crowd inside Arthur Ashe Stadium—with a 6-3, 7-5 upset of Serena Williams in the women’s singles final. Andreescu becomes the first Canadian to win a Slam singles title in the Open era.

Williams was chasing history at the US Open, trying to become the match-wins leader and the player with the most Open-era singles titles in Flushing Meadows (she is tied with Chris Evert for both, at 101 and six, respectively); and chasing that elusive 24th Slam singles title.

“I’m sure I’m not the only person that’s looked up to her. She’s an inspiration to many, many people, not only athletes. What she’s done off the court, too. She’s truly a champion.

“Above all, she’s very kind-hearted. She came up to me in the locker room, she said some really nice things, which I’ll cherish for a really, really long time.

“But, yeah, I’ve really strived to be like her. Who knows? Maybe I can be even better.” — Bianca Andreescu, on Serena Williams
