Key storylines

Caroline Wozniacki's comeback continues: At Montreal, The Dane won her first match in three years, where she came out of retirement to defeat Kimberly Birrell in straight sets. She bowed out in the next round to reigning Wimbledon champion Marketa Vondrousova. She's been granted a main-draw wild card in Cincinnati. Her best result at the tournament came in 2014 when she made the semifinals before losing to Serena Williams. 

Ons Jabeur returns to competition: The Wimbledon finalist skipped Montreal with a knee injury. She is still entered in Cincinnati, which will be her only hard-court tournament before the US Open where she made the final last year. 

Iga Swiatek continues to hold off Aryna Sabalenka: The World No.1 ensured she would leave Montreal with the No.1 ranking after defeating Karolina Muchova to make the quarterfinals. Depending on the results in Canada, her top spot could be under threat again in Cincinnati. Last year, Swiatek made the Round of 16, while Sabalenka was a semifinalist. 

Jessica Pegula and Coco Gauff continue to build steam: The spotlight will be bright for the two top-ranked Americans in New York and they've both enjoyed solid summer hard-court seasons so far. Pegula made the semifinals in Washington D.C., while Gauff walked away with the biggest title of her career there. They continue to look sharp in Montreal in both singles and doubles.
