World number ones Jannik Sinner and Iga Swiatek both turned around losing situations on Saturday to move into the semi-finals of the ATP and WTA Cincinnati Open. Sinner prevented rival Andrey Rublev from repeating a triumph from last Saturday in Montreal as he defeated the sixth seed in a 4-6, 7-5, 6-4 fightback. Swiatek did the same in the women's draw as she worked to overcome teen Mirra Andreeva 4-6, 6-3, 7-5. Sinner will square off in the semis against third-ranked 2021 champion Alexander Zverev, who got past rain interruptions in the final set to defeat Ben Shelton 3-6, 7-6 (7/3), 7-5.
