The Canadian champion beat Serena Williams 6-3 and 7-5 on Sept. 7. I’ve dreamt of this moment for a really long time but I never thought it would come this soon...It’s definitely been one of my dreams to play her and so it was just a really good opportunity for me, Bianca Andreescu, to ABC News. Williams, who was favored to win, holds 23 Grand Slams titles, only one title short of the all time record. Despite her loss, the superstar had only positive things to say, praising Andreescu for an “unbelievable match.”. I'm just so proud that I'm still out here and competing at this level because it's not easy to be in this particular sport for 20 years, Serena Williams, to ABC News.
