ATP Miami Open Round-Up Day Two | Grigor Dimitrov exits early, Fonseca and Tsitsipas headline winners

The delayed start to the Miami Open finally gave way to a full slate of first-round action, with several notable names progressing alongside one of the standout upsets of the day. Joao Fonseca and Stefanos Tsitsipas advanced in contrasting fashion, while Matteo Berrettini delivered a controlled win to continue his steady form. In one of the biggest surprises, Grigor Dimitrov was eliminated in a deciding-set tiebreak by Raphaël Collignon.

The results carry immediate implications across the draw. Dimitrov’s early exit is set to cost him heavily in the rankings following his semifinal run last year, while Fonseca continues to build momentum with a high-profile clash against Carlos Alcaraz next. Tsitsipas, meanwhile, opens his campaign with a solid win as he looks to re-establish consistency at Masters 1000 level, and Berrettini’s performance signals growing confidence after his return to form.

Joao Fonseca defeated Fábián Marozsán 6-4, 3-6, 6-2 to secure his place in the second round, delivering a composed performance in key moments to close out a competitive match. The Brazilian made a strong start, breaking early in the opening set and maintaining control behind his serve, landing 76% of first serves and winning 75% of those points. Marozsán remained close but was unable to convert his late opportunities on return.

The momentum shifted in the second set as Marozsán raised his level under pressure. A crucial hold from 0-40 in the opening game allowed the Hungarian to stabilise, and he later secured a break in the fourth game to take control. Fonseca struggled to make inroads on return during this stretch, as Marozsán served more effectively and shortened points to avoid extended rallies.

In the decider, Fonseca quickly regained control. He broke early by attacking second serves and dictating from the baseline, then consolidated for a 3-0 lead. The Brazilian finished with 12 aces and just one double fault, maintaining consistency on serve even in tight moments. He closed out the match after sustained pressure forced an error from Marozsán, sealing a second-round meeting with Carlos Alcaraz in one of the standout matches to come.

Stefanos Tsitsipas advanced with a 6-1, 7-6 victory over Arthur Fery, producing a strong opening set before being tested late in the match. The Greek dominated early, racing to a 5-0 lead with two breaks of serve and controlling play from the baseline. He dictated rallies with his forehand and remained solid behind serve, allowing Fery little opportunity to build momentum in the opening stages.

The second set proved far more competitive. Fery improved his serving numbers and began applying pressure in return games, eventually earning three set points. Tsitsipas responded with composure, relying on his serve to escape the critical moments. He finished the match winning 77% of first-serve points and an impressive 73% on second serve, while also saving all three break points faced.

The match was ultimately decided in a tiebreak, where Tsitsipas maintained his level to close out the win in straight sets. Despite the drop in dominance after the opening set, he avoided any significant momentum swing by protecting his serve throughout. The result sends him into a second-round clash with fifth seed Alex de Minaur, a matchup that will test his consistency from the baseline and defensive resilience.

Matteo Berrettini defeated Alexandre Müller 6-4, 6-2 in a controlled performance built around his serve and first-strike tennis. The Italian secured an early break in the third game of the opening set and did not face a break point, maintaining control from the outset. His ability to dictate with the forehand limited Müller’s opportunities to extend rallies and shift the balance of play.

Berrettini landed 73% of first serves and won 71% of those points, while also saving all four break points he faced across the match. He finished with 22 winners compared to Müller’s 11 and applied steady pressure on second serve, winning 50% of return points in those situations. As the match progressed, he stepped further inside the baseline, taking time away from Müller and increasing the tempo of exchanges.

The second set became more one-sided as Berrettini converted his opportunities more efficiently, breaking twice to seal the win without complications. His combination of serving consistency and controlled aggression ensured there were no momentum swings. He now advances to face 10th seed Alexander Bublik, in a matchup likely to be defined by serve dominance and short rallies.

Denis Shapovalov was eliminated in the opening round after a 7-5, 6-3 loss to Botic van de Zandschulp, in a match where the Dutchman proved more efficient in key moments. The Canadian, a former Miami semifinalist, stayed competitive through much of the opening set, but a late break tilted the momentum. Van de Zandschulp closed strongly, winning 12 of the last 15 points to secure the set.

The difference between the two players became clearer as the match progressed. Van de Zandschulp delivered a consistent performance on serve, landing 77% of first serves and winning 75% of those points. In contrast, Shapovalov struggled to build pressure on return, winning just 25% of first-serve return points. The Dutchman also proved more effective in break-point situations, saving five of six opportunities while converting four breaks across the match.

Shapovalov was unable to shift that dynamic in the second set. Although he had periods where he dictated with his forehand, errors at key moments prevented him from sustaining pressure. Van de Zandschulp remained composed, protecting his serve and capitalising on chances to extend his lead.

The defeat continues an inconsistent run for Shapovalov, who exits early in Miami despite past success at the tournament, while Van de Zandschulp moves into the second round with a controlled and tactically disciplined performance.

Moïse Kouamé recorded one of the standout results of the session, defeating Zachary Svajda 5-7, 6-4, 6-4 to claim his first Masters 1000 main-draw victory. The 17-year-old showed composure despite losing the opening set late, where Svajda capitalised on a key break to edge ahead after a largely even contest from the baseline.

The turning point came early in the second set. Kouamé faced 0-40 at 4-3, a moment that could have effectively ended the match, but responded by saving all three break points and holding serve. That escape shifted the momentum. From there, the Frenchman became more assertive on return, stepping inside the baseline and taking control of rallies more consistently. His improved positioning allowed him to dictate play rather than react, reducing errors and increasing pressure on Svajda’s service games.

In the deciding set, Kouamé maintained that level, handling key points with greater clarity and protecting his serve more effectively than in the opener. While full match statistics were limited, the pattern was clear: after surviving that critical game in the second set, he controlled the match. The win marks a significant milestone for the teenager in his first Masters 1000 appearance and highlights his ability to adjust tactically under pressure at this level.

Grigor Dimitrov was eliminated after a 7-6, 4-6, 7-6 loss to Raphaël Collignon, in one of the most dramatic matches of the session. The Bulgarian, who reached the semifinals in Miami last year, entered with significant points to defend but was unable to close out the match despite holding a late advantage. The opening set was decided in a tiebreak, with both players holding serve consistently before Collignon edged the key moments.

Dimitrov responded in the second set, raising his level on serve and securing a single break to level the match. He struck 23 aces and won 80% of points behind his first serve, maintaining control for long stretches. However, inconsistencies, including eight double faults, prevented him from fully capitalising on his advantage.

The decisive set saw Dimitrov move into a 5-3 lead and earn a match point, but he was unable to convert. Collignon recovered to force a tiebreak and handled the closing stages more effectively. The defeat is set to have significant ranking consequences, with Dimitrov expected to fall outside the top 85. It marks one of the most damaging early exits of the opening round.
