Adolfo Daniel Vallejo stretched his run at the ATP Cincinnati tournament into the Round of 32 but came up short Friday on the Grandstand when 18th-seeded Tommy Paul rallied for a 3-6, 6-3, 6-4 victory.
Match swings on return numbers and second-serve points
The match, contested on hardcourt, tightened to a margin of just two aggregate points — Paul finished with 87 to Vallejo’s 85 — but a few critical moments and differing performances on second serves decided the outcome.
Vallejo opened strongly, taking the first set 6-3 by controlling service exchanges and limiting break chances against him. He won 22 service points in the opener to Paul’s 15 and faced only a single break point, converting his lone opportunity on Paul’s service game. Vallejo also constructed the longest run of points in that set with an eight-point streak.
- First set: Vallejo captured 6-3, aided by cleaner second-serve play.
- Second set: Paul answered with a five-game run to flip momentum.
- Third set: Return points against Vallejo’s second serve proved decisive.
Second-set charge gives Paul control
Paul reversed course in the second set, winning it 6-3 behind a more consistent first serve. He landed 67% of first serves in that set, turning those deliveries into 14 of 18 points (about 78%) and recording three aces. Paul’s returning also intensified: he took 8 of 16 return points on Vallejo’s first serve and converted two breaks to build the set win.
Vallejo did stave off three of five break points in the second set, but the two conversions that slipped away proved costly. The Paraguayan’s service-game count fell from five in the first set to four in the second, a scoreboard shift that highlighted the mounting pressure on his service games.
Deciding set decided by second-serve pressure
The final set remained close in baseline exchanges and first-serve battles, but second-serve statistics again tilted the match. Paul won 7 of 10 return points against Vallejo’s second serve — a strong 70% — and that hold on return pressure produced the critical break that sealed the match 6-4 in the third.
"No tiebreaks were needed, just steady shifts in momentum,"
That line — recorded by match trackers on-site — captures the bare-bones flow of a contest that hinged on a handful of pivotal points rather than prolonged dominance.
| Set | Score | Notable stat |
|---|---|---|
| 1 | 6-3 (Vallejo) | Vallejo won 22 service points; Paul 15; Vallejo 9/13 second-serve points (69%) |
| 2 | 6-3 (Paul) | Paul 67% first serves; 14/18 first-serve points (78%); 3 aces |
| 3 | 6-4 (Paul) | Paul 7/10 return points vs. Vallejo second serve (70%) |
Overall, Paul finished the match two points ahead in the aggregate tally — 87 to 85 — an indication of how narrow the margin was. Trackers and stat pages for the match logged the shifts in momentum and the small number of swing points that separated victory from defeat.
For Vallejo, the match offered a mix of encouragement and clear targets for adjustment. Strong serving and a clean first-set performance demonstrated his capacity to dictate points, while the second-serve vulnerability and the handful of missed break opportunities underlined where the match turned. For Paul, the match reinforced how tactical returning and timely serving can overturn an early deficit even when total points are nearly even.
Vallejo’s run to the Round of 32 at a Masters-level event like Cincinnati will register with local fans as a notable performance on a big stage, and the narrow scoreline suggests he remains competitive against top-20 opposition when key moments fall his way.
