Second round action at the ATP 250 in Brisbane features four intriguing matches on Wednesday, with top seed Daniil Medvedev taking center stage. Who will reach the quarterfinals?
ATP Brisbane Day 4 Predictions
Sebastian Korda vs Jiri Lehecka
Head-to-head: Lehecka 2-0 Korda
Jiri Lehecka has played some of his best tennis on Australian soil, winning his two ATP titles on this continent. The defending champion upstaged countryman Tomas Machac in a tough opener. Korda, for all the early promise and hype in his career, has yet to convert it into tangible success. So, this could be a big season for the American because confidence in tennis can quickly slip and never be regained. Lehecka owns this matchup, but if Korda can put the physical problems behind him, he’s got the higher upside.
Prediction: Korda in 3
Alex Michelsen vs Learner Tien
Head-to-head: Michelsen 2-1 Tien
The praise that Learner Tien has garnered in the past year has been fully merited. He’s coming off one of the best seasons by an American Next Gen star. And Tien graduated from that group by winning the Next Gen title last month. However, beating Michelsen at the Tour level remains an obstacle. Tien lost both meetings in straight sets when they played last season. But Tien’s game is much more refined right now. He’s also less reactive under pressure and can construct points efficiently.
Prediction: Tien in 3
Reilly Opelka vs Kamil Majchrzak
Head-to-head: Opelka 1-0 Majchrzak
Reilly Opelka’s career appeared to take off when he beat Novak Djokovic en route to making the Brisbane final last year, until injury cruelly forced him to retire in the title match. But he recovered to enjoy a respectable season, making multiple other quarterfinals. Opelka’s serve still dictates a lot of free points, and Majchrzak’s return weight is not consistent enough to neutralize that.
Prediction: Opelka in 2Â
Daniil Medvedev vs Frances Tiafoe
Head-to-head: Medvedev 5-2 Tiafoe
Medvedev is the top seed in Brisbane, but the Russian has lost the favorite tag in the last couple of years, even as the highest-ranked player in the tournament. That said, he is not resigned to that reality and admitted he aims to challenge for top honors this season. There are glimpses of improvement since he changed his coaching team, and he started the tournament with a clinical straight-sets win. Tiafoe endured a broadly inconsistent season in 2025, and he is another player hoping for better results this year. Medvedev has dominated this matchup primarily due to his baseline stubbornness and ability to slow the pace. His core strengths remain intact, so he will likely retain the edge again.
Prediction: Medvedev in 3
