ATP Miami Open Quarterfinals Round-Up | Jannik Sinner and Alexander Zverev deliver dominant straight-sets wins to set up semi-final meeting
ATP
The Miami Open quarter-finals concluded with two one-sided contests, as Jannik Sinner and Alexander Zverev advanced with straight-sets victories to complete the semi-final lineup. Both matches followed a similar script, with early breaks defining the trajectory and little fluctuation in momentum. The Miami Open continues to reward first-strike tennis, particularly from players able to combine efficient serving with sustained return pressure.
Sinner arrived as the highest-ranked player remaining in the draw and confirmed that status with another controlled performance, while Zverev produced one of his cleanest matches of the tournament. With both players progressing from the quarter-finals without significant resistance, the second Masters 1000 of the Sunshine Double now sets up a semi-final meeting between two of the most consistent performers in the field.
Sinner neutralises Tiafoe through return efficiency
Jannik Sinner def. Frances Tiafoe 6-2, 6-2
Jannik Sinner advanced to the Miami Open semi-finals with a structured victory over Frances Tiafoe, controlling the match from the opening game. The Italian broke immediately and quickly extended to a double-break lead, shaping a first set that lasted under 35 minutes. Tiafoe struggled to establish service patterns, while Sinner maintained short, efficient service holds throughout.
The central tactical dynamic came on second-serve exchanges. Sinner consistently stepped forward on return, reducing reaction time and forcing Tiafoe into defensive positions from the first shot. Attempts by the American to increase aggression resulted in a higher error rate, particularly when trying to shorten rallies without stable court positioning.
From a statistical standpoint, Sinner’s advantage was built on serve reliability and return depth. He won 82% of first-serve points and 67% behind his second serve, while also capturing 49% of return points on Tiafoe’s first delivery. Tiafoe, by contrast, won just 51% of first-serve points and held only four of eight service games, limiting his ability to apply scoreboard pressure.
The result continues Sinner’s consistent trajectory through the Miami Open, where he has avoided extended matches and preserved physical margin. He now moves into the semi-finals to face Alexander Zverev, in a matchup that will likely hinge on first-serve patterns and baseline tolerance rather than short-point execution alone.

Zverev exposes baseline imbalance to dismantle Cerundolo
Alexander Zverev def. Francisco Cerundolo 6-1, 6-2
Alexander Zverev reached the Miami Open semi-finals with a dominant performance over Francisco Cerundolo, establishing control from the opening service games. The German secured an early break and extended quickly to 4-0, capitalising on Cerundolo’s difficulty in finding rhythm off the ground. The first set was effectively decided within the opening 20 minutes.
The match developed around Zverev’s targeted pressure to Cerundolo’s backhand wing. By sustaining depth and directing rallies into that side, Zverev forced repeated neutral-ball errors, preventing the Argentine from constructing offensive patterns. Cerundolo attempted to accelerate exchanges, but this led to further inconsistency rather than disrupting Zverev’s structure.
Serving efficiency further separated the players. Zverev landed 76% of first serves and won 84% of those points, while also securing 70% behind his second serve. In contrast, Cerundolo won just 35% of second-serve points and held only three service games across the match, limiting his capacity to reset between return games.
This performance positions Zverev as one of the most stable contenders remaining in the Miami Open draw, particularly given his service reliability under minimal pressure. He advances to face Jannik Sinner in the semi-finals, with both players arriving without significant physical or tactical disruption through the quarter-final stage
