The second round of the 2025 US Open continues on Day 5 with many scintillating matchups. No. 1 seed Jannik Sinner squares off against the always-fiesty Alexei Popyrin. Elsewhere across the grounds, we have previews and predictions for Stefanos Tsitsipas vs Daniel Altmaier<\/a>, Alexander Zverev vs Jacob Fearnley<\/a>, and Tommy Paul vs Nuno Borges<\/a>. Offering their insights are Ateet Shrivastava, Damian Kust, and Nurein Ahmed. But who will advance?<\/p>\n

US Open Day 5 Men’s Predictions<\/h2>\n

Gabriel Diallo vs Jaume Munar<\/h4>\n

Ateet<\/strong>
\nGabriel Diallo hit 17 aces against Damir Dzumhur to get back-to-back first-round wins at the US Open. It was a tight match lasting well over 3 hours, and Diallo played a great fourth set to close it out. Jaume Munar has played at a high level on hard courts this season, and his first-round win against Jaime Faria was a testament to that. I expect a battle in this one, but going with the Canadian.
\nPrediction: Diallo in 5<\/em><\/p>\n

Damian<\/strong>
\nThe new and improved hard-court Munar is a proper threat this year, and this should be closer than their meeting at the US Open 12 months ago. Diallo has improved a lot since, but his weaponry will have to be on point against a grinder with a slightly more offensive mindset these days.
\nPrediction: Diallo in 5<\/em><\/p>\n

Nurein<\/strong>
\nThis is the best we\u2019ve seen Munar perform outside clay. He\u2019s recorded a string of good results on hard courts this season, which he can fancy his chances of reaching the third round of the US Open for the first time. Ultimately, Diallo\u2019s shot tolerance and his massive serve will give him the edge if he can rack up cheap points from the baseline.
\nPrediction: Diallo in 4<\/em><\/p>\n

Adam Walton vs Coleman Wong<\/h4>\n

Ateet<\/strong>
\nAdam Walton played one of his best matches at a Grand Slam to get his first US Open win. He was more solid than Ugo Humbert and got broken just once in the entire match. Coleman Wong continued his impressive run from qualifying to get a straight-sets win in the first round. Both players are in good form and played a close match when they met earlier this season. I\u2019ll give a slight edge to Walton.
\nPrediction: Walton in 5<\/em><\/p>\n

Damian<\/strong>
\nWong posted a big win over Shelton in Miami and then lost to Walton. Maybe history will repeat itself here. But it would be nice for him if it doesn\u2019t, he\u2019s flying the flag for Hong Kong as the first man representing the country in a Grand Slam main draw in the Open Era. He\u2019s got the higher upside and needs to try not to crumble against the solid game of Walton.
\nPrediction: Wong in 5<\/em><\/p>\n

Nurein<\/strong>
\nTo say the draw has been kind to Walton and Wong is an overstatement. Both players earned it. Walton took out a seed in his opening, and Wong battled three rounds of qualifying and then knocked out a Top 100 player to reach the second round. This will probably be scrappy, but Walton\u2019s low-margin game and superior ground strokes might tilt this in his favor.
\nPrediction: Walton in 5<\/em><\/p>\n
