Sierra’s Grit Seals Argentina’s United Cup Breakthrough
In Perth’s buzzing arena, Solana Sierra’s emphatic third-set turnaround against Jessica Bouzas Maneiro clinched Argentina’s first 2026 United Cup win over Spain, building on Sebastian Baez’s solid opener and igniting hopes for group advancement.

In the charged atmosphere of Perth’s RAC Arena, Argentina grabbed the 2026 United Cup’s opening victory, edging Spain 2-0 in Group A. Sebastian Baez’s 6-4, 6-4 win over Jaume Munar set a firm foundation, but Solana Sierra’s 6-4, 5-7, 6-0 battle against World No. 41 Jessica Bouzas Maneiro delivered the decisive punch. As the highest-ranked players from their country—Baez at No. 45 and Sierra at No. 66—they carried the weight of three prior group-stage failures, turning early-season nerves into national momentum on the slick indoor hard courts.
“It was a really tough match. I just tried to focus on my game. I was doing really good, then at 5-2 in the second set, I was not playing too good. But I’m really proud of how I kept going in the third set,” the 21-year-old said after just her second-ever tour-level win over a player from Spain.
Baez builds early lead through composed breaks
World No. 45 Sebastian Baez made his United Cup debut with a 6-4, 6-4 victory over Jaume Munar in 1 hour and 43 minutes, improving to 2-0 in their head-to-head. Trading breaks early in the first set, he struck at 4-4 with a crosscourt forehand winner that exposed Munar’s backhand, then held serve to close the frame amid rising crowd energy. In the second, after dropping serve for a 3-2 deficit, Baez broke right back with an inside-in backhand, using heavy topspin to dictate longer rallies on the moderate-bounce surface.
He saved four of six break points overall, his footwork allowing quick redirects that kept the Spaniard off-balance. This marked Baez’s first Top 50 win since defeating then-No. 46 Mariano Navone en route to the Rio title last February, a boost after two injury-riddled years. The 24-year-old’s patience in baseline exchanges absorbed Perth’s partisan cheers, channeling them into a steady rhythm that eased pressure on his teammates.
In the first match of the 2026 ATP Tour season, World No. 45 Baez defeated Munar to give Argentina a 1-0 lead over Spain.
“I really enjoyed this moment, enjoyed the time on court, so happy to [have] won this point for Argentina,” he said.
Baez’s recovery added emotional depth, his one–two patterns pulling Munar forward before finishing with down-the-line passes. As Argentina savored the lead, the team’s huddle on the sidelines pulsed with shared relief, the mixed format’s camaraderie contrasting solo-tour isolation.
Sierra’s adjustments turn setback into dominance
Sierra’s match against Bouzas Maneiro stretched to 2 hours and 2 minutes, her heavy topspin forehands controlling the first set’s extended points for a 6-4 edge. She built a 5-2 second-set lead, reaching 30-30 on serve at 5-3 and breaking for 5-4, only to lose five straight games as unforced errors mounted and the Spaniard’s flat returns exploited shorter balls. That collapse forced a decider, but Sierra emerged refocused, losing just eight points in a 6-0 third-set bagel.
Her shifts were tactical: deeper returns neutralized Bouzas Maneiro’s serve, while mixing underspin slices disrupted the baseline flow, opening angles for inside-out winners. This victory marked Sierra’s third career win over a Top 50 opponent and her second tour-level success against a Spanish player, her grit shining through the arena’s shifting murmurs. The 21-year-old’s composure under team scrutiny highlighted her mental growth, transforming frustration into a clinical finish.
“I’m super happy to start the year competing and representing Argentina. it’s a different week, sharing the week with all the team. We are enjoying every moment.”
The hard courts’ pace favored Sierra’s adjustments once she shortened her strokes for consistency, jamming Bouzas Maneiro with low-bouncing returns. Crowd roars swelled with each third-set point, the expat flags waving as Argentina’s hopes crystallized in her dominance.
Team momentum targets group escape
With Baez and Sierra’s wins, Argentina tops Group A, eyeing their first advancement after three stalled attempts. The duo’s baseline styles thrived on Perth’s true bounce, where Baez’s break-back at 3-3 relied on crosscourt pressure and Sierra’s third-set efficiency limited errors to a minimum. Baez’s post-match words captured the squad’s unity, his injury comeback fueling collective belief amid the tournament’s high-stakes ties.
