The WTA is returning to Cincinnati this week for one final tuneup before the U.S. Open.

The lineup features five major champions among the top eight, including world No. 1 Ash Barty and world No. 2 Naomi Osaka.

On Saturday, Osaka announced she would be donating all of her prize money to relief in Haiti after a 7.2 magnitude earthquake hit the country.

Coco Gauff is the youngest player in the draw at 17 years old. She could meet Osaka in the second round. It would be the first meeting between the two since Gauff defeated Osaka at the 2020 Australian Open.

Meanwhile, Victoria Azarenka returns as the defending champion and could meet Barty in the third round.

Tokyo gold medalist Belinda Bencic is set for a rematch with her Olympic finals opponent Marketa Vondrousova in the first round.

The main draw begins Monday, Aug. 16 with the singles final set to be played Sunday, Aug. 22.
