German tennis player Daniel Altmaier fell short of an upset in the quarterfinals of the ATP tournament in Lyon, dropping a straight-set decision to American Taylor Fritz 6-7 (5-7), 2-6. The 28-year-old from Kempen, ranked No. 65 in the world, put up a fierce fight in the opening set against the 2024 US Open finalist before fading against the heavy serve of his opponent.
The loss halted Altmaier’s momentum in a tournament where he had displayed flashes of his best tennis. Facing the current world No. 14, Altmaier managed to push the first set to a tiebreak through tenacious baseline defense, but he failed to carve out a single break point across the entire match against Fritz’s dominant service games. In the second set, the American favorite seized control early and managed the match safely to the finish line.

Altmaier Beat Fritz at 2025 French Open
The quarterfinal clash offered a stark contrast to their only previous meeting on the ATP Tour. At the 2025 French Open, Altmaier secured one of the biggest victories of his career by knocking off Fritz—who was then the world No. 4—in a four-set first-round battle on the Parisian clay.
Entering the Lyon draw, the trajectories of both players pointed to a difficult test for the German underdog. While Fritz anchored his status, Altmaier arrived looking to build upon a productive summer grass-court swing. Most notably in mid-June, Altmaier advanced past the round of 16 at the grass-court tournament in Halle, Westphalia, pushing all the way to the semifinals before exiting.
Fritz Dominates with Superior Serving Performance
Fritz’s serving performance proved to be the decisive factor on the court. By neutralizing Altmaier’s return game, the American kept pressure on the German’s service games throughout the two-set encounter. Altmaier fought through long rallies in the first set, extending points and forcing Fritz into mistakes during the tiebreak, where the score remained close at 5-7.
However, the inability to generate break chances ultimately starved Altmaier of opportunities to shift the momentum. Once Fritz broke early in the second set, the American utilized his superior service speed and court coverage to close out the contest in straight sets.
