Denis Shapovalov vs Daniel Altmaier Preview

Denis Shapovalov is ranked 26th in the ATP rankings and is the seventh seed in Tokyo this week. This will be Shapovalov’s fourth main draw appearance in Japan’s capital. He is a two-time semifinalist, but last played this event in 2022, where he lost to Taylor Fritz in three sets in the last four.

Shapovalov has secured his Top 30 return this season with a series of good performances and results. He added to his trophy cabinet by winning two titles. Shapovalov was in inspired form back in February, where he defeated multiple top 10 opponents to win the Dallas title. He won his second ATP title in late July at the Los Cabos Open in Mexico. It’s the first time he’s won two titles in the same season, doubling his career tally.

Daniel Altmaier is ranked 49th in the ATP rankings and is unseeded at the Tokyo Open. This will be his second appearance at the event. Altmaier was knocked out in the first round during his only visit two years ago against Tommy Paul in three sets.

Altmaier has compiled 28 wins and 29 losses this term. His best results have been on clay, where he holds a 13-8 record in 2025, but he reached the third round of the US Open against the odds, with victories over Hamada Medjedovic and Stefanos Tsitsipas in five sets.

Shapovalov needed five sets to beat Altmaier in their only meeting at the 2024 Wimbledon Championships.

Denis Shapovalov vs Daniel Altmaier Prediction

Shapovalov arrives in Tokyo fresh from tying the knot with retired WTA player Mirjam Bjorklund. He’s played some of his best tennis in this tournament, reaching two semifinals in the past. Altmaier doesn’t quite have a great track on hard courts, where the quickness of the surface reduces his reaction time. A player like Shapovalov, who blends power with athleticism, will look to dictate and should do so easily.
