Last week, the WTA Tour hosted a WTA 1000 tournament in Cincinnati, in addition to a WTA 125 series event in Chicago. While the World No.1 Ashleigh Barty emerged victorious at the Western & Southern Open, a pair of teenagers, Clara Tauson and Emma Raducanu, battled in the final in Chicago.

Barty reaches 90 weeks at top

Barty’s reign atop the WTA Rankings continues. She enters her 83rd consecutive week and 90th overall atop the rankings, the ninth most all time. Barty will need to protect her No.1 ranking for another eight weeks to equal Lindsay Davenport’s 98 weeks at No.1 in order to move into eighth place.
