Il Nuovo Postiglione - Serena says goodbye to Canada after defeat by Bencic

The second-round defeat by Switzerland's reigning Olympic gold medallist was hardly unexpected, with the 40-year-old Williams competing in only her third match of 2022.

Bencic fired eight aces and broke Williams twice in the first set and once in the second, advancing on her first match point after 78 minutes.

But as Bencic herself said in the post-match interview on court: "tonight is about her."

Williams's farewell on-court interview was threaded with emotion.

"I love playing here, I've always loved playing here," she said, choking up as fans who cheered her throughout the match called out their appreciation.

"I wish I could have played better tonight, but Belinda was playing so well."

Williams, who turns 41 next month, had beaten Spain's Nuria Parrizas Diaz on Monday for her first singles victory since the 2021 French Open, 14 months ago.

But it sent shockwaves through the sport when she revealed in an essay in Vogue magazine and an Instagram post on Tuesday that "the countdown has begun" to her retirement from the sport.

Williams didn't specify an actual retirement date but is expected to compete next week in Cincinnati before travelling to the US Open, which starts on August 29.

She has lifted the US Open title six times, including her first Grand Slam triumph at the age of 17 in 1999.

"It's been a pretty interesting 24 hours," said Williams, who remains one shy of the all-time record of 24 Grand Slam singles titles won by Margaret Court.

"Like I said in my article, I'm terrible at goodbyes," she said, her voice breaking.

"But, goodbye," she said, then adding with a laugh "Toronto."

- 'A joy playing here' -

"I've always had an amazing time here on and off the court," Williams said. "I've had some really good matches and some really cool wins.

"It's been a joy playing here all of those years."

Williams's match was preceded by a video tribute played for fans. Before she left the court she was presented with jerseys from the NBA's Toronto Raptors and NHL's Toronto Maple Leafs -- and with a child's version of the same for daughter Olympia.

In explaining that she was "evolving away" from tennis in the Vogue article, Williams said she wanted to focus on family life and new business ventures.

Her appearance highlighted a day that saw US teenager Coco Gauff -- who says Williams was "the reason why I play tennis" -- overcome 13 double-faults to battle past Wimbledon champion Elena Rybakina and into the third round.

Gauff beat Rybakina 6-4, 6-7 (8/10), 7-6 (7/3) while world number one Iga Swiatek -- who beat Gauff in the French Open final this year -- sailed past Australian Ajla Tomljanovic 6-1, 6-2 in 55 minutes.

Gauff lost out on four chances to close out a straight-sets victory as a quartet of match points came and went.

Kazakhstan's Rybakina, aided by Gauff's service struggles, had looked as if she might pull off another marathon victory after squeezing past Marie Bouzkova in the first round only for Gauff to finally prevail.

Swiatek, in contrast, needed just 55 minutes to advance. The top-seeded Pole, with six titles this season, saved six of the nine break points she faced.

"From the first practice I played here I felt really good," Swiatek said.

Defending champion Camila Giorgi made it to the third round with a 6-3, 7-5 defeat of Belgian Elise Mertens. Spanish fourth seed Paula Badosa lasted for just 13 games before retiring as she trailed 7-5, 1-0 against Kazakh Yulia Putintseva.
