Britain’s Arthur Fery beat Australia’s James Duckworth at the Cincinnati Open, in his first match since making a shock run to the Wimbledon semi-finals last month.

Elsewhere, Novak Djokovic revealed he has an ongoing health condition as the 24-time Grand Slam champion struggled with the hot and humid conditions during a shock defeat by Argentina’s Thiago Tirante.

Fery, who had jumped to a career-high world ranking of 36 following his Wimbledon success, won 6-4 2-6 7-6 (7-4) in two hours and 34 minutes against Duckworth in Ohio as he warms up for the US Open later this month.

The 24-year-old was given a wildcard into his home Grand Slam, having been ranked 114th in the world before the start of the tournament and having never been beyond the second round of a Grand Slam, and defied all expectations to reach the semi-finals where he lost to Alexander Zverev.

Following Wimbledon he took some time off and then went into a training block at the National Tennis Centre in Roehampton.

Seeded 32nd in Cincinnati in what is just his second Masters 1,000 event, he will play Australian fifth seed Alex de Minaur in the next round.

Fellow Brit Cameron Norrie is out, losing 3-6 6-3 6-3 to Germany’s top seed Zverev.
