Federico Diaz Acosta came through 4-6, 6-3, 7-6 against Jaume Munar in Seville, edging a decider that went the full distance without a single break of serve. The two were separated by almost nothing over three sets: both won 57 service points, both converted three break points, both held 12 of their 15 service games.
Diaz Acosta broke first in game two of the opening set for 2-0, but Munar hit back with breaks in game five (2-3) and game seven (4-3) to take it 6-4. The second set swung the other way: Munar broke in game three at 2-1, only for Diaz Acosta to reply immediately in game four and break again in game six for 4-2 on his way to 6-3. In the third there were no breaks at all, and the tie-break settled it.
The decider was where Diaz Acosta was at his most solid behind his delivery: 15 of 16 first-serve points won (94%) and all seven second serves held up, while Munar managed just one of 16 return points against his first serve. Across the match Diaz Acosta saved only 2 of 5 break points to Munar's 4 of 7, so this was a win built on the serve in the final set rather than superiority on return.
