Sunday was historic for Canadian Bianca Andreescu.  Not only was she facing Serena Williams in the Final in Toronto, but she had a chance to become the first Canadian to win the tournament in 50 years.

The match started out great for the Canadian as she went up 3-1 on the legendary Williams, but then something nobody saw coming happened, Williams retired from the match due to injury.

Andreescu won the match and the tournament in shocking fashion, but a win is a win and it was a historic one at that.  Once the match was over, many took to social media to congratulate the 19-year-old on her incredible accomplishment.
