Friday's quarterfinals saw the two semi-finalists emerge victoriously in grueling three-set battles to set up this match:

Holger Rune (ATP Rank No. 11) edged out Tomás Martín Etcheverry (ATP Rank No. 32) in a gritty three-set victory (Score: 6-7(4), 6-3, 6-4). Rune showed immense guts having lost the opening set, exhibiting his characteristic fighting spirit to take it despite clear signs of agony with a left leg issue.

Ugo Humbert (ATP Rank No. 26) defeated his experienced opponent, Lorenzo Sonego (ATP Rank No. 46), once more in three sets (Score: 6-7(3), 6-0, 6-3). The victory was a show of Humbert's top-notch form, securing him a fourth semi-final appearance of the year and advancing his head-to-head against Sonego to 6-3.

• Head-to-head H2H: Holger Rune holds the head-to-head advantage over Ugo Humbert 4-0.

• Key Insight: Rune boasts a commanding historic advantage over the Frenchman on hard-court surfaces. The Dane has won a mere one set in all his encounters with Humbert, including his triumph at the Basel indoor tournament in 2022.

Stockholm History: Rune took his first hard-court title here in 2022 and provided him with a high comfort level on these specific indoor courts.

Motivation: The fight for the Nitto ATP Finals is an immense motivational factor, and a strong run in Stockholm is critical to his season's ranking.

Indoor Record: Humbert is known to be a quick-court specialist, dominating the hard court indoors, which adapts well to his attacking style of play.

Record: He is following his pursuit of maintaining his spotless 4-0 record at the quarter-final stage during 2025.

Rune's Strategy: Rune needs to rely on "first-strike tennis" and solid serving in order to make the points short and nullify Humbert's option of grinding the rallies.

Humbert's Strategy: The French left-hander will attempt to finish off points quickly, employing his slice serve to the ad court to extend the court and take pressure off his backhand.

Rune: Vulnerable to spells of collapse and over-ambition when in difficulties. Post-match interviews after the quarter-final reveal him confessing to being "struggling" with a left leg injury, casting doubt over his fitness.

Humbert: Occasionally sensitive to pressure when unable to dictate the rhythm and commits unforced errors (29 in last 2-set H2H).

The semi-finals will be decided by the player who adapts best to the fast indoor conditions and plays most consistently and aggressively. While Rune has the overwhelming H2H advantage, his recent physical battle with Etcheverry introduces an important wild card. If Rune is nearing 100% physically, his superior clutch play and experience in Stockholm should allow him to control the rhythm of the match and win.

• Prediction: Holger Rune wins.

• Final Score Prediction: Holger Rune beats 2-1 (6-4, 5-7, 7-6(4)).

Holger Rune's victory is conclusive to his prospects of qualification to the Nitto ATP Finals. Ugo Humbert, meanwhile, is making a very serious, dark-horse bid on the indoor swing. The semi-final will produce the tiebreaks that decide the path to the Stockholm final, giving value to efficiency and mental resilience over the next day's play. Ultimately, the game is perhaps more a test of whether Rune can recover from his draining quarter-final and use the home-court advantage to succeed.
