Alex De Minaur faces Reilly Opelka in round two of the Cincinnati Open this morning, fresh off a title run at the DC Open last month.
The Australian has established himself as one of the hardest hitters and most consistent defenders during the North American hard-court swing, following his feat in Washington by defeating Frances Tiafoe in the Round of 16 in Toronto, where he fell to the ascendant Ben Shelton in the quarterfinals.
Despite that loss, the momentum is clear, with de Minaur climbing up the rankings. He’s presently ranked No. 8 — close to his career high.
His hallmark speed, defensive grit, and ability to absorb pressure make him a consistent contender on hard courts.
Opelka, ranked No. 73, counters with a significant, albeit singular, weapon — his serve. The towering 6’11” American has reached the final in Brisbane earlier this year and remains dangerous when his serve is firing, having already beaten Novak Djokovic, Holger Rune, and Daniil Medvedev in 2025.
However, his consistency and court movement still fall short of elite standards. With a largely one-dimensional game, this match will hinge on his serve: if it’s clicking and the aces are flowing, he can trouble de Minaur.
If not, the advantage will swing decisively to the Australian — as it has in all their previous meetings.
De Minaur–Opelka Head-to-Head
De Minaur holds a dominant 5–0 lead in their H2H.
His ability to blunt Opelka’s biggest weapon was clear in Basel in 2019, where, even after being out-aced 26–14, he held Opelka to just 76% of first-serve points won while winning 85% on his own, showing both defensive skill on return and superior serving efficiency.
Prediction
De Minaur in 2 straight sets. His defensive resilience and counterpunching should prevail over Opelka’s serve-dominated game.
