World number one Ashleigh Barty reached her sixth final of the season on Saturday as the Australian defeated Angelique Kerber 6-2, 7-5 at the ATP and WTA Cincinnati Masters.

The 25-year-old top seed has led the ranking table for the past 82 weeks. Barty needed just an hour and a quarter to move into Sunday's title match, surpassing her semi-final showing from 2019.

Barty will play for the trophy against Swiss wild card Jil Teichmann who shocked Naomi Osaka, Olympic gold medalist Belinda Benci, and Czech fifth seed Karolina Pliskova in this tournament. 

Against Kerber, Barty increased her lead in the series between multiple Grand Slam winners to 4-2 as she duplicated a Wimbledon semi-final victory from last month.

On the men's side, Tokyo Olympics gold medalist Alexander Zverev came from two breaks down in the third set to beat Stefanos Tsitsipas 6-4, 3-6, 7-6 (7/4), setting up Sunday's final against Andrey Rublev. 

The German, who briefly left the court to vomit in the final set as he stepped up his fightback in front of a full crowd, will take a 4-0 record into the final.

Fourth-seeded Rublev surprised world number two compatriot Daniil Medvedev 2-6, 6-3, 6-3 in the semi-final.

Also on Saturday, China's Zhang Shuai and Australian Sam Stosur claimed the women's doubles title, defeating sixth-seeded Gabriela Dabrowski of Canada and Luisa Stefani of Brazil 7-5, 6-3.
