Halle Open ATP Semi-finals Round-up | Taylor Fritz ends Zverev run, as Frances Tiafoe reaches final in dominant fashion

The Halle Open semi-finals produced contrasting narratives, with Taylor Fritz ending Alexander Zverev’s 10-match winning streak in a tightly contested three-set battle, while Frances Tiafoe delivered a more controlled straight-sets victory over Daniel Altmaier. Fritz’s 7-6, 4-6, 7-5 win was defined by serve-heavy exchanges and a decisive late break in the final set, whereas Tiafoe imposed sustained return pressure to take the victory 6-1, 6-3.

The results set up a final between two of the tour’s most efficient grass-court servers, with Fritz extending his strong post-injury form after missing the clay swing and Tiafoe advancing through a low-variance performance built on early breaks and consistent service holds. Zverev exits despite pushing Fritz deep into a decider, while Altmaier was unable to generate sustained resistance against Tiafoe’s return dominance across both sets.

Zverev began the match with early structural control, establishing a 3-1 lead while holding comfortably behind serve in the opening stages. Fritz initially struggled to generate return pressure, with Zverev dictating shorter baseline exchanges and maintaining a higher first-serve rhythm before Fritz stabilised through extended holds.

The first set shifted into a serve-dominant pattern before reaching a tiebreak. Zverev held momentum through consistent service games and closed the breaker efficiently, dropping only one point after reaching 3-2 in the mini-break sequence. Fritz, however, adjusted in the second set by improving return depth and forcing longer service games, eventually breaking late in the set to level the match and halt Zverev’s control phase.

The decider remained on serve through a sequence of holds from 1-1 to 5-5, with neither player generating sustained break pressure in neutral rallies. At 5-5, Fritz applied late return pressure as Zverev’s first-serve percentage dropped, earning a decisive break before serving out the match. The American completed a 2-hour-44-minute victory, ending Zverev’s 10-match winning streak and reaching the final through superior late-stage execution on return points.

Tiafoe established immediate control of the semi-final through aggressive return positioning and a high first-serve conversion rate behind his own delivery. The American broke early and quickly moved into a double-break lead in the opening set, consistently targeting Altmaier’s second serve and preventing any sustained baseline rhythm from developing.

The first set became one-way from the middle phase onwards, with Tiafoe winning five consecutive games to close it out 6-1 without facing a break point. His ability to convert both break opportunities while maintaining a secure service pattern ensured Altmaier never gained scoreboard traction, with the German repeatedly forced into defensive positions on return games.

The second set began with more stability on serve, as both players held early games before Tiafoe increased return pressure to secure the first break for 3-2. From there, he maintained control of the set through efficient service holds, keeping Altmaier at arm’s length and limiting any chance of a momentum swing. At 5-3, Tiafoe closed the match with a late break, finishing the contest in straight sets and advancing without having to face a significant break-point threat across the match.
