Preview WTA Finals Day Five: Jessica Pegula holds the cards as Coco Gauff faces must-win scenario
WTA
The final round of Group 1 at the 2026 WTA Finals will determine the last semifinalist from the section, with Jessica Pegula and Coco Gauff still competing for the remaining spot alongside an already-qualified Linda Noskova. The Czech has secured her place in the last four after winning both opening matches, while Marta Kostyuk has been eliminated following consecutive defeats.
Pegula enters the final day with the advantage after recovering from her opening loss to Gauff with a 6-2, 7-5 victory over Kostyuk. The American will now face Noskova, knowing that a win would guarantee her progression regardless of the result in the other encounter. She could also finish top of the group, although that will depend on the number of sets required to secure victory.
Gauff, meanwhile, has a more complicated route after losing 6-3, 6-3 to Noskova in her second match. The reigning 2024 WTA Finals champion must defeat Kostyuk and hope the Czech also beats Pegula to secure the second qualification spot. A victory for Pegula would eliminate that possibility, leaving the American with no margin for error against an opponent who has nothing left to play for in terms of semifinal qualification.
Noskova is the only player who already knows she will be competing in the semifinals, but the Wimbledon champion still has an important objective. Winning at least one set against Pegula would guarantee first place in the group, even if she eventually loses the match.
A straight-sets victory for the American, however, would allow her to overtake the Czech, making the final round of Group 1 a particularly intriguing test of both sporting quality and tournament mathematics.
Linda Noskova vs Jessica Pegula: Czech looks to maintain perfect record as American targets qualification
Noskova and Pegula will meet for the fifth time, with the Czech holding a 3-1 advantage in their head-to-head. The 21-year-old has already demonstrated her ability to compete against the strongest players at Indian Wells, winning both opening matches without dropping a set. Pegula, meanwhile, has gradually recovered after her difficult start and now has an opportunity to reach another WTA Finals semifinal.

Noskova has enjoyed the biggest breakthrough of her career this season. Her Wimbledon triumph established her among the elite of the women’s Tour while her performances at the WTA Finals have provided further evidence of her progress. She defeated Kostyuk in her opening match before producing an impressive display against Gauff, taking advantage of the American's serving difficulties to win 6-3, 6-3.
The Czech has also shown considerable composure in the round-robin format, particularly when dealing with the pressure of her debut. Her aggressive baseline game and ability to take the ball early have made her difficult to contain, while her serve has provided a reliable foundation throughout the tournament. Having already secured qualification, she can approach this encounter with greater freedom, although finishing first would offer another important reward.
Pegula has had to work considerably harder to reach this position. Her opening defeat against Gauff left her needing a response, and she delivered against Kostyuk, recovering from a competitive second set to secure a straight-sets victory. The American remains one of the most consistent players on the tour, having reached five finals during the 2026 season and claimed titles in Dubai and Charleston.
Her experience at the WTA Finals could also prove valuable. Pegula reached the championship match in 2023 and the semifinals last year, making this her fifth consecutive appearance. She knows how to navigate the pressure of the season-ending championships, although her opening defeat means she cannot afford another setback.

The head-to-head offers an additional challenge for the American, with Noskova winning three of their four previous encounters. The Czech has demonstrated that she can disrupt Pegula's rhythm through aggressive returning and early ball-striking, preventing the American from settling into her preferred baseline patterns.
Pegula will need to use her consistency and court coverage to extend rallies, particularly if Noskova looks to dictate with her forehand. The American's ability to redirect pace and exploit shorter balls could be decisive, but she must also remain aware of the qualification implications.
At times, Noskova has been brilliant from the baseline, while at other moments, she has benefited from her opponents' persistent errors—a trend seen throughout this week at Indian Wells, which has been marked by erratic performances from several players. This may well be the key for Pegula: limit her own unforced errors, manage to prolong the rallies, and force her opponent to take greater risks.
Coco Gauff vs Marta Kostyuk: Former champion needs victory (and a favour)
The second encounter brings together two players in very different positions. Gauff still has a chance to reach the semifinals, while Kostyuk has already been eliminated following defeats against Noskova and Pegula. Nevertheless, the Ukrainian will have an opportunity to finish her campaign with a victory, potentially complicating the qualification battle for the American.
| Statistic | Coco Gauff | Marta Kostyuk |
| Ranking | No. 4 | No. 9 |
| Age | 22 | 24 |
| 2026 titles | 1 | 2 |
| Best 2026 achievement | Cincinnati champion, two Grand Slam semifinals | Madrid champion, two Grand Slam semifinals |

Gauff started her campaign positively by defeating Pegula in three sets, but her defeat against Noskova exposed some of the problems that have affected her game throughout the season. Her serve was particularly vulnerable, allowing the Czech to secure repeated breaks and take control of the match. The American finished with eight double faults and struggled to establish consistent patterns behind her first delivery.

The 22-year-old nevertheless has considerable experience at this tournament, having won the title in 2024 and reached the semifinals back in 2023. Her season has also included a Cincinnati title and further deep runs at Grand Slam level. However, she now needs to produce a convincing performance against Kostyuk while keeping an eye on the outcome of the other match.
Kostyuk, meanwhile, will be disappointed with how her WTA Finals debut has unfolded. The Ukrainian entered the tournament as a late replacement for Elena Rybakina, but consecutive straight-set defeats have ended her chances of reaching the semifinals. Her 6-2, 7-5 loss against Pegula was particularly frustrating after she struggled to limit her unforced errors in the opening set.

The 24-year-old has nevertheless enjoyed a strong season, collecting two titles and reaching the semifinals at both the Australian Open and Roland Garros. She has also demonstrated her ability to trouble leading opponents, and her aggressive style could still create problems for Gauff if she manages to find consistency.
Gauff leads their head-to-head 4-2 and will look to use her superior movement and defensive skills to neutralise Kostyuk's attacking approach. The Ukrainian will need to take the initiative and prevent Gauff from controlling exchanges, particularly given the American's ability to turn defensive positions into offensive opportunities.

Ultimately, Gauff's qualification hopes depend on two separate results. She must defeat Kostyuk and hope Noskova beats Pegula. If the American wins but Pegula also secures victory, Gauff will be eliminated regardless of her own performance.
With Noskova already through and Kostyuk playing for pride (and 200 points for the winner), the final Group 1 matches will provide a decisive conclusion to the battle for the second semifinal position.
