Cincinnati, United States, 12 August 2019 | tennis.com.au / AAP

Alex de Minaur won through to the second round of the Cincinnati Masters with a come-from-behind victory over Marco Cecchinato.

The Italian won the opening set before De Minaur charged away with a 6-7(5) 6-1 6-2 win to set up a meeting with either 12th seed Borna Coric or American wildcard Reilly Opelka.

“These wins are often the ones that count the most,” De Minaur told reporters. “To be able to come back from not playing my best tennis and turn it around, I’m really happy to get the win.”

De Minaur extended Cecchinato’s losing streak to 10 matches; he also defeated the 26-year-old in the opening round of Wimbledon last month.
