The latest Croatia Open Umag 2026 news — a daily update from every day of play: results, upsets, and the storylines that shaped the day. Newest first.
Eleven breaks decided the Umag final, and Daniel Merida Aguilar banked seven of them. The ATP No. 82 beat Damir Dzumhur 6-2 5-7 6-2 for his first title on record, converting 7 of 12 break points and winning half of his return games while his own serve leaked eight double faults to Dzumhur's one. The return paid the serve's debts. Dzumhur, ATP No. 108, converted 4 of his 6 break chances and took the second set 7-5, but held only 7 of 14 service games and 49 percent of first-serve points to Merida's 62.
The run to it carried weight of its own, as Merida's round-of-16 win over ATP No. 30 Tomas Martin Etcheverry matched the best win by rank on his record. The Croatia Open Umag hands its 2026 trophy to a man who arrived holding none.
Break-point conversion decided Day 5 at the Croatia Open Umag. Damir Dzumhur, ATP No. 108, went 0-for-6 on break chances as Alex Molcan banked the opener 6-3, then converted 3 of 4 in the decider and closed the 3-6 6-4 6-3 comeback with a break in game 9, 2 hours, 43 minutes in. A day earlier he beat ATP No. 34 Matteo Arnaldi in the quarterfinals — the No. 2 win by opponent rank on his record.
In the other semifinal, ATP No. 82 Daniel Merida Aguilar held eight of nine service games and won 71 percent behind both first and second serves in a 6-4 6-2 win over Roman Andres Burruchaga, the highest-ranked of the four semifinalists at No. 67, who saved three match points before Merida converted a fourth. The title match is set: No. 82 against No. 108, with no prior meetings on record.
Umag's three remaining seeds played Thursday's quarterfinals; none survived. The heaviest exit was No. 2 seed Alejandro Davidovich Fokina, ATP No. 20 and the highest-ranked man left in the draw, who won the opener but three games after, as ATP No. 101 Alex Molcan held 11 of 12 service games in a 3-6 6-1 6-2 upset while taking 79 percent of first-serve points to 69 across the net.
Two courts over, Damir Dzumhur, ATP No. 108, needed 3 hours, 36 minutes to edge No. 4 seed Matteo Arnaldi 7-6(5) 6-7(4) 7-6(4), erasing a 2-5 opening-set hole with breaks in games 8 and 10. Also Thursday, Roman Andres Burruchaga outlasted No. 7 seed Camilo Ugo Carabelli 6-2 2-6 6-3, and Daniel Merida Aguilar held Titouan Droguet to four games, 6-1 6-3. The Croatia Open Umag semifinals now hold no seeds and nobody inside the top 60: Burruchaga vs. Merida Aguilar and Dzumhur vs. Molcan.
Umag's top line lasted 98 minutes into Day 3. Roman Andres Burruchaga, ATP No. 67, beat top seed Flavio Cobolli 6-2 6-4, breaking four times from seven chances as the ATP No. 9 landed 49% of first serves. It was his first top-10 win on record — the previous high was ATP No. 22 Learner Tien.
Also Wednesday, No. 3 seed Tomas Martin Etcheverry fell to ATP No. 82 Daniel Merida Aguilar, and Alex Molcan advanced when Dino Prizmic retired down 0-4 in the third. The other seeds held — No. 2 Alejandro Davidovich Fokina over Marco Trungelliti, No. 4 Matteo Arnaldi in three past Federico Agustin Gomez, No. 7 Camilo Ugo Carabelli from a set down on Pablo Carreno Busta — while Titouan Droguet and Damir Dzumhur completed the last eight at the Croatia Open Umag. The quarterfinal field keeps three seeds, ATP No. 20 Davidovich Fokina the highest-ranked man left.
Two days into the Croatia Open Umag, the seed line is thinning again. Titouan Droguet, ATP No. 116 and winless since April on a four-match slide, dropped the opening set to No. 5 seed Alexander Blockx, then took 12 of the final 14 games in a 3-6 6-2 6-0 upset — Droguet converted five of 10 break points while Blockx, leaking seven double faults, won just one of 11 return games.
No. 7 seed Camilo Ugo Carabelli nearly followed, going 2-of-9 on first-set break points and splitting tiebreaks with qualifier Marko Topo, ATP No. 350, before closing it 6-7 7-6 6-3. Also Tuesday, Pablo Carreno Busta conceded six games to wild card Matej Dodig, and the slate's other five matches all ended in straight sets. Three seeds have taken the court in Umag so far; Ugo Carabelli is the only one still standing.
The only seed on Day 1 at the Croatia Open Umag is already gone. Dino Prizmic, ATP No. 89 and 7-5 on clay this season, allowed No. 8 seed Vit Kopriva just four games in a 6-1 6-3 win built on ruthless big-point math: four break points earned, four converted; three faced, three saved; 86% of first-serve points won behind eight holds in eight service games.
The other three openers went to the higher-ranked player. Luca van Assche survived the day's only three-setter, recovering from a set down to edge Dusan Lajovic 2-6 7-5 6-4, while Damir Dzumhur and Marco Trungelliti needed a combined 2 hours 18 minutes to move past Henrique Rocha 6-2 6-1 and Kyrian Jacquet 6-2 6-3.
