Williams continued to weep as she addressed the crowd in Toronto after the match. "It's been a tough year but I'm going to keep going".
After Williams' retirement, the former world No. 1 player began to cry on her bench. The 23 time Grand Slam champion explained this was not the first time she had experienced a similar issue with her back. "You've dealt with so much in your career, this is just a minor setback for a major comeback, I'm sure". "I thought it maybe would have changed my perspective completely on things, but I'm sitting here disappointed, which I think is probably a good thing, and if I want to get back to playing at a high level, if I was sort of just happy to be back on the court and not really anxious about the outcome, then I'd be a bit maybe concerned about that".
In fact, many will argue Andreescu, a two-time junior doubles champion having won in Melbourne and Paris in 2017, possesses a far more diverse and complex game than the aforementioned Canucks. Williams will look to recover in time for the U.S. Open at the end of the month.
Williams, 37, said she would make the trip to Cincinnati before deciding whether she would play.
"So that´s a little bit frustrating for me because I know that I could play. I'll have to wait and see".
Andreescu, meanwhile, said she was "speechless" and branded the victory a "dream come true".
"This wasn't the way I expected to win".
"I'm not a crier, but, thank you, guys. You are truly a champion on and off the court".
The 74-year-old grew up in west Windsor and in 1969 became the last Canadian female tennis player until Sunday to win what was then called the Canadian Open and later became the Rogers Cup.
"This week has not been easy".
Bianca Andreescu (L) tries to console Serena Williams (R) after she withdrew from the championship match during the Rogers Cup tennis tournament at Aviva Centre in Toronto, Canda, on August 11, 2019. She withdrew from the Miami Open in March because of a knee injury.
And while Williams was keeping her Cincinnati options open, Andreescu was taking no chances, announcing later Sunday that she would skip the OH event.
