Marta Kostyuk delivered a stunning demolition of sixth-ranked Jessica Pegula, winning 6-0, 6-3 in Brisbane to set up a final showdown with world No. 1 Aryna Sabalenka. The Ukrainian's masterclass performance marked her third consecutive victory over a top-10 opponent at the Brisbane International. Meanwhile, Coco Gauff helped keep the United States' hopes alive with a commanding 6-4, 6-2 win over Iga Swiatek in their United Cup semifinal clash.
Kostyuk's demolition job stuns Brisbane
In what can only be described as a complete dismantling, Marta Kostyuk handed Jessica Pegula one of the most lopsided defeats of her career. The 26th-ranked Ukrainian needed just under an hour to dispatch the American 6-0, 6-3, overturning their head-to-head deficit with ruthless efficiency. Kostyuk entered the match trailing 4-1 in their career series, having lost both encounters in 2025, but showed no signs of that previous dominance from Pegula.
The pressure point statistics told the complete story of Kostyuk's dominance - she won 8 of 14 return pressure points while saving both break points she faced. Her clinical serving display yielded four aces against just one double fault, maintaining a 79% first serve winning percentage throughout. This remarkable run through Brisbane has now seen Kostyuk defeat three consecutive top-10 opponents, matching her 2024 Stuttgart achievement and bringing her career total of top-10 victories to 12.
Sabalenka cruises past Muchova
Aryna Sabalenka showed exactly why she's the world No. 1, dispatching Karolina Muchova 6-3, 6-4 in the earlier semifinal. The Belarusian was virtually untouchable on serve, saving all four break points she faced and winning 13 of 16 serve pressure points in a dominant display. Her powerful baseline game proved too much for the Czech, who had stunned third seed Elena Rybakina in the quarterfinals.
Sabalenka's path to the Brisbane final has been remarkably smooth, with the top seed yet to drop a set. She struck five aces against just one double fault, breaking Muchova twice from eight opportunities. The victory sets up an intriguing final against Kostyuk, who has been the story of the tournament with her giant-killing run through the draw.
Gauff levels United Cup semifinal
In Sydney, Coco Gauff delivered when her country needed her most, defeating second-ranked Iga Swiatek 6-4, 6-2 to level the United Cup semifinal between the United States and Poland. The American showed impressive resilience under pressure, winning 16 of 32 return pressure points while maintaining her composure when serving for the crucial moments.
Gauff's victory came after Poland's Hubert Hurkacz had stunned Taylor Fritz in the opening rubber, making his remarkable comeback from seven months out with knee surgery. The fourth-ranked American's win forced a decisive mixed doubles rubber, keeping alive their hopes of reaching a second consecutive United Cup final. Her pressure point statistics of 12 of 20 serve pressure points won demonstrated her ability to rise to the occasion on the biggest stage. The singles victory did not materialize though, as Gauff w/ Christian Harrison got defeated by Polish mixed doubles pairing - Katarzyna Kawa and Jan Zielinski. Kawa and Zielinski made the job done same as during quarterfinals against Australia on Friday, sending their team into 3rd consecutive United Cup final.
Svitolina survives Auckland thriller
Elina Svitolina showed all her championship experience to outlast Iva Jovic 7-6(5), 6-2 in a hard-fought Auckland semifinal. The 13th-ranked Ukrainian weathered an early storm from the young American, who took the opening set to a tiebreak before Svitolina's class ultimately prevailed. The former world No. 3 won 13 of 27 return pressure points, showcasing her ability to capitalize when her opponent was under the most stress.
Svitolina's victory wasn't without its struggles, as she faced six break points throughout the match while converting five of eight opportunities on Jovic's serve. The three-time Grand Slam semifinalist struck three aces but also committed three double faults in what proved to be an entertaining encounter. Her experience in the biggest moments ultimately proved the difference as she advanced to her first final since returning from maternity leave.
Wang completes Auckland comeback
Xin Yu Wang produced the comeback of the day in Auckland, rallying from a set down to defeat Alexandra Eala 5-7, 7-5, 6-4 in an epic three-set semifinal. The Chinese player showed remarkable mental strength after losing the opening set, winning 19 of 45 return pressure points to gradually wear down her opponent's resistance.
The match featured dramatic swings throughout, with Wang saving 13 of 19 break points faced while converting seven of 15 opportunities. Her serving was particularly impressive in the decisive moments, firing 10 aces against seven double faults in a performance that showcased both power and precision. The victory sets up an all-Asian final against Svitolina, as both players look to claim their first WTA title of the 2026 season.
Sunday's action will feature the Brisbane final between Sabalenka and Kostyuk, with the Ukrainian looking to continue her remarkable giant-killing run against the world No. 1. The Auckland final between Svitolina and Wang promises to be an intriguing clash of experience versus youth, while the United Cup final will be determined after the mixed doubles rubber between the United States and Poland.
Sunday's championship showdowns
Sunday's WTA action delivers a rare triple-header of finals across three continents, with world No. 1 Aryna Sabalenka and No. 2 Iga Swiatek both seeking early-season silverware. The United Cup features Swiatek against resurgent Belinda Bencic for the team competition victory, while Sabalenka battles rising star Marta Kostyuk in Brisbane's climax. Meanwhile, Elina Svitolina aims for her first title since motherhood against breakthrough talent Xinyu Wang in Auckland.
Polish power meets Swiss precision in United Cup finale
The United Cup final pits Swiatek's overwhelming recent dominance against Bencic's perfect hard-court form, creating a fascinating clash of contrasting trajectories. The Polish star holds a commanding 5-1 head-to-head advantage, including their most recent encounter at Wuhan just three months ago, but faces an opponent riding a remarkable 10-match winning streak.
Swiatek's hard-court excellence over the past 12 months speaks volumes, posting a 40-12 record with particularly strong return numbers - converting 51.5% of break point opportunities while neutralizing opponents' first serves at a 41.4% clip. Her pressure-point statistics reveal a player who elevates her game when it matters most, saving nearly 60% of break points faced in crucial moments.
Bencic arrives as the form player, boasting a flawless 10-0 recent record that has catapulted her back into the top tier. The Swiss veteran's 32-11 hard-court record over the past year demonstrates consistent excellence, though her 3.0 double faults per match could prove costly against Swiatek's aggressive return position. Her 58.3% break point save percentage shows resilience under pressure, but history suggests she'll need to exceed that mark significantly to trouble the world No. 2.
Sabalenka's dominance meets Ukrainian determination
The Brisbane final showcases Sabalenka's pursuit of consecutive Australian swing titles against Kostyuk's breakthrough campaign, with the Belarusian's perfect 4-0 head-to-head record telling only part of this compelling story. Both players arrive with identical four-match winning streaks, but their paths to this moment reveal contrasting strengths.
Sabalenka's 84.4% hard-court winning percentage over the past 12 months ranks among the tour's elite, powered by exceptional serving depth - her 4.0 aces per match and mere 1.9 double faults per match create a devastating foundation. Her 8-3 tiebreak record suggests composure in decisive moments, while her 66.3% break point save percentage demonstrates the mental fortitude that has defined her recent success.
Kostyuk enters as a dangerous underdog, her 5.9 double faults per match presenting a clear vulnerability that Sabalenka will target relentlessly. However, the Ukrainian's 3.5 aces per match and 65.6% break point save percentage indicate she won't surrender easily. Her recent 8-2 record across the last 10 matches shows growing consistency, though her 4-6 tiebreak record could prove decisive if this final reaches the wire.
Experience battles youth in Auckland showdown
The Auckland final presents Svitolina's quest for redemption against Wang's emerging talent, with their lone previous meeting at Wimbledon 2024 providing little insight into this hard-court battle. The Ukrainian veteran seeks her first title since returning from maternity leave, while the Chinese player chases her maiden WTA trophy.
Svitolina's 66.7% hard-court winning percentage reflects steady progress in her comeback journey, though her concerning 2-6 tiebreak record over the past year highlights potential vulnerability in tight moments. Her 3.7 aces per match and solid 68.9% first-serve points won demonstrate that her serving foundations remain strong, while her 46.9% break point conversion rate shows she can capitalize on opportunities.
Wang arrives with modest expectations but dangerous form, her 14-14 hard-court record masking recent improvement that has delivered four consecutive victories. The 22-year-old's 2-7 tiebreak record mirrors her opponent's struggles in decisive moments, potentially setting up a final determined by who handles pressure better. Her 42.7% break point conversion rate lags behind Svitolina's experience, suggesting the veteran holds a crucial edge in the match's pivotal moments.
Three finals across multiple time zones promise compelling conclusions to an eventful week, with established stars and emerging talents battling for early-season momentum. Coverage begins with the United Cup finale, followed by decisive action from Brisbane and Auckland as the 2026 season gains momentum.
