Alejandro Tabilo rallied from a set down to defeat Thiago Agustin Tirante 4-6, 6-3, 6-3 in the Round of 16 at the ATP Santiago on Friday. The Chilean converted his serve into a weapon after dropping the opening set, dominating second-serve points at 68% to Tirante’s 44% and winning 90 total points to his opponent’s 77.
Tirante controlled the first set with aggressive returning, breaking Tabilo twice while winning both break-point opportunities he faced. The momentum shift arrived in the second set when Tabilo tightened his ground game and began punishing Tirante’s weaker second serve. The Argentine’s five double faults proved costly, and his second-serve struggles allowed Tabilo to seize control. The four-time tour champion broke serve twice in both the second and third sets, converting 4 of 12 break chances while Tirante managed just 2 of 3.
Tabilo closed out the match by winning 12 of the final 16 games, hammering 36 winners—five more than his opponent—while keeping unforced errors nearly identical at 27 to Tirante’s 28. His seven aces matched Tirante’s power but his consistency on second-serve points made the difference on Santiago’s hard courts.
Key Takeaways
- Tabilo’s second-serve dominance was decisive: he won 68% of second-serve points compared to Tirante’s dismal 44%, a 24-percentage-point chasm that proved insurmountable after the first set.
- The Chilean converted 4 of 12 break-point opportunities while Tirante went just 2-for-3, with Tabilo’s ability to create more chances (12 versus 3) reflecting his sustained pressure throughout the final two sets.
- Tirante’s five double faults—more than double Tabilo’s two—undermined his serve in crucial moments, particularly as the match wore on and the pressure mounted.
- Despite identical first-serve percentages (62%), Tabilo extracted more value from his delivery, winning 73% of first-serve points and powering 36 winners to control rallies and dictate terms.
Player Analysis
Alejandro Tabilo
The Chilean showcased the mental fortitude that has earned him four career titles, refusing to fold after dropping the opener. Tabilo’s adjustments after the first set were surgical: he elevated his aggression on return games, attacked Tirante’s second serve relentlessly, and kept his own unforced-error count at a manageable 27 despite going for his shots. His 68% success rate on second-serve points was extraordinary, nearly matching his first-serve effectiveness and suggesting he found a rhythm from the baseline that Tirante couldn’t disrupt.
The serving numbers tell the story of a player who grew more confident as the match progressed. Seven aces demonstrated pop, while just two double faults indicated composure under duress. Tabilo’s ability to create 12 break-point chances—even if he converted only four—kept Tirante constantly defending, draining the Argentine’s legs and spirit over three competitive sets.
Thiago Agustin Tirante
The title-less Argentine started brilliantly, snatching the first set with aggressive returning and crisp ball-striking that had Tabilo reeling. Tirante’s early break conversions (2-for-2 in the first set) suggested he had the tools to close out a quality opponent on a quick hard court. But his second serve—winning just 44% of points—became a glaring liability once Tabilo adjusted his return position and began teeing off on weaker deliveries.
Five double faults at critical junctures compounded Tirante’s struggles, and his inability to generate consistent break-point opportunities (just three for the entire match) left him defending far too often. The winner-to-unforced-error ratio of 31 to 28 wasn’t catastrophic, but the lack of firepower compared to Tabilo’s 36 winners revealed a player who couldn’t sustain his aggression deep into the second and third sets.
