Bianca Andreescu made Canadian tennis history on Saturday, defeating Serena Williams to win the 2019 US Open title.

The 19-year old entered 2019 ranked 152nd in the world but she ended it as a Grand Slam champion and will be ranked in the top 10 when the new rankings come out on Monday. Andreescu became the first Canadian to win a major singles championship with a 6-3, 7-5 victory over Williams.

In that moment the Twitter hashtag #SheTheNorth changed to #SheTheChamp.

In the process of capturing the US Open championship, Andreescu denied Williams of another opportunity to claim a record-tying 24th Grand Slam title. The 37-year old now has lost in each of her last four appearances in a majors final.

Andreescu played one hell of a match, hitting with accuracy and power while handling her nerves in front of a raucous crowd that was pro-Williams. She converted six break points while being aggressive from the first serve of the match, right until the final point.

On the other hand, Williams didn’t seem to be her usual self on the court. She committed eight double-faults, including one that ended the first set. She would only make 44% of her first serves.

With Williams trailing 5-1 in the second set, she took some energy from the partisan crowd, saving championship point and won four consecutive games. However, Andreescu made sure the American got no closer.

Following the match, during the on-court interviews, Andreescu had a very Canadian moment when the Mississauga, Ontario was asked “As things tightened in that second set Bianca, what did you have to overcome to get across the finish line?”

With a chuckle she acknowledged that the crowd was the major thing to overcome and went on to say “I know you guys wanted Serena to win so I'm so sorry. Obviously, it was expected for Serena to fight back. She's done that so many times in the past, that's why she's a true champion on and off the court, but I just tried my best to block everything out.”

She continued, "The last game wasn't easy. She started serving way, way better too; balls were going all over the place. So, I'm just glad with how I managed, really."

As US Open champion, the Canadian took home a cheque for $3.85 million.
