Round 1 results in the Stefanie Graf group

If Pegula and Gauff win, Pegula tops the group, Paolini is eliminated, and Sabalenka and Gauff will decide the second semifinal slot on Thursday.

If Paolini loses 0-2, she is out, and any other combination will be settled in the final matches on Thursday.

Gauff (3) vs Paolini (8)

The head-to-head is tied at 3-3, and given Gauff’s form today, the American will try to repeat her late-season edge on Paolini, who has proven dangerous with her serve and return pressure. Paolini has shown she can disrupt rhythm with aggressive serves, so Gauff will want to tighten her own service discipline and minimize unforced errors.

Gauff encountered trouble in her opener against Pegula, with the three-set result marking the only match of the day to go the distance. She committed several unforced errors on her forehand, and freeing her game while maintaining pace will be key against Paolini.

Paolini’s three wins against Gauff this year—Cincinnati, Stuttgart, and Rome—underscore her ability to modulate offense and capitalize on weak returns. Her Rome triumph marked a historic Italian victory in the event for four decades, a milestone she still has in her pocket as a motivator.

Both players have the capacity to break serve—Paolini did so multiple times across their head-to-heads this season, and Gauff will need clean serving and smart shot selection to neutralize that pressure, especially under the Riyadh lights.

Arena Sabalenka (1) vs Jessica Pegula (5)

Sabalenka holds an 8-3 edge in their head-to-head, and today her power game remains a touchstone of her title defense. She did not waste time in her opener, cruising through 70 minutes with 24 winners and only a single-digit error count on serve, while Pegula’s resilience and variety kept her in the fight in the second set.

Pegula’s run against Sabalenka this year has shown she can disrupt with depth and pace, and she previously defeated Sabalenka in Wuhan, a performance that demonstrated her ability to shift momentum with strategic returns and pressure on second serves. If Pegula can manage Sabalenka’s smoke-off shots while limiting her own lapses, she can again threaten a top-ranked performance.

Mentally sharp and tactically flexible, Pegula’s best tennis this season has put her among the few Americans capable of beating No. 1 on big stage nights, a line of achievement that has historically been rare in the Finals era, with only a handful of players pulling off such feats since 2003.

Records and context

Statistically, Sabalenka’s form in the Finals has been formidable, while Pegula’s late-season surge has boosted her confidence against top-ranked opponents in pivotal matches. The event stresses not just pure power, but the ability to adapt under pressure and manage the unique round-robin format of Riyadh this year — a true test of consistency and nerve.

Looking back at history, Martina Navratilova remains the benchmark with eight Finals titles and a historic run across 21 editions, while Monica Seles and Serena Williams sit high on the all-time list for most finals and matches in this event. The modern era continues to write new chapters, with Pegula’s recent breakthroughs signaling a second American generation that can thrive at the top of the sport, following the greats who paved the way.

United States tennis has claimed 21 Finals titles, with Germany and Belgium close behind in the all-time distribution, while the current field tests a new balance of power and endurance as the Riyadh schedule unfolds. The stage is set for a week of drama, and the group’s dynamic is far from settled, promising a climactic finish to the round-robin phase.
