No.1s Jannik Sinner, Iga Swiatek Stage Cincy Fightbacks As Alexander Zverev Escapes

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.

Top seed Sinner took to the court for only his second match of the week after a first-round bye and a walkover on Friday.

Zverev has won four of five matches against Sinner -- three at Grand Slams, including last year's US Open.

Sinner -- whose fitness has been compromised in recent months by a hip niggle, illness and the tonsillitis which forced him to miss the Olympics -- stormed back to win the second set and break Rublev to start the third.

He clinched victory in a set where five of the 10 games were breaks of serve. His match point ball was caught by a gust of wind and put out of the reach of his opponent.

"There was a lot of mental strength required today," Sinner said. "It was tough conditions, very, very windy.

"In the first set I didn't play my best tennis. In the second I improved and was able to wait for
