Vit Kopriva vs Quentin Halys — R128 — Cincinnati Open

Conversion on return decided a match with few openings: Halys took three of his four break points while Kopriva managed two of five. Twelve aces to two kept the qualifier ahead of the serving exchange, and his break in game 9 for 5-4 shut the second set, 1 hour and 41 minutes in. That extends to six the streak that began with the Kitzbühel title over Bublik — carried now into a Cincinnati main draw he had to qualify for.
