Serena Williams and Emma Raducanu will prepare for the US Open with a WTA 1000 tournament in Toronto.

Both Williams and Raducanu have signed up for the Canadian Open, which will take place from August 6th to 14th.

In total, 41 of the 43 highest-ranked players on the WTA Tour will compete, including world number one and two-time Grand Slam winner Iga ÅšwiÄ…tek.

Naomi Osaka, Coco Gauff and home favourite Bianca Andreescu are also on the start list.

“When you read over that star-studded list, it’s hard not to get excited about the WTA Tour making its return to Sobeys Stadium,” said Karl Hale, Canadian Open tournament director.

“Not only is this one of the strongest, if not the strongest, player list we’ve ever submitted, but it’s also the first time in three years that the National Bank Open returns to a full capacity.

“We’re thrilled that these players will have a chance to play in front of a packed house, and we’re even happier for our fans who will get to watch tennis’ very best at the 2022 edition of the National Bank Open.”

Williams’s inclusion means her participation at the US Open, scheduled for August 29th to September 11th, is even more likely.

The 40-year-old made her return to tennis after a year-long absence at Wimbledon, although she was defeated by Harmony Tan in the first round. Despite the loss, Williams revealed her motivation to play at next month’s Grand Slam.

"When you're at home, especially in New York, and the US Open, that being the first place I've won a Grand Slam, is something that's always super special," she said. "Your first time is always special.

"There's definitely lots of motivation to get better and to play at home."

Williams is still chasing a record-equalling 24th Grand Slam – her last came at the Australian Open in 2017.

Eyes will also be on Raducanu, who will arrive at Flushing Meadows next month as the defending champion.

The 19-year-old has struggled to find her feet on the WTA Tour since her historic victory at the US Open, but still entered the world top 10 earlier this week.

She became the fifth British woman to break into the top 10 since the WTA Rankings computer system was introduced, joining Virginia Wade, Sue Barker, Jo Durie and Johanna Konta.
