Jack Draper advanced to the quarter-finals of the Cincinnati Open after a controversial win over Félix Auger-Aliassime, which ended in a disputed match point. Draper claimed a 5-7, 6-4, 6-4 victory, but Auger-Aliassime argued that Draper's final shot was illegitimate, having deflected off his racket frame. Despite the Canadian's protests, the chair umpire upheld the call, and Draper moved on to face Holger Rune next. This victory came after Draper had already beaten Stefanos Tsitsipas in a hard-fought three-set match and survived a tough first-round match against Jaume Munar. Meanwhile, in the women's event, defending champion Coco Gauff was defeated in the opening round by Yulia Putintseva.
