Marin Cilic defeated Pablo Carreno Busta 5–7, 6–3, 7–6 in the Davis Cup Finals quarter-final on hard court. The Croatian recovered from losing the opening set to take control in the second, then edged a competitive third-set tiebreak to secure his place in the semi-finals. Carreno Busta mounted early pressure and claimed the first set, but Cilic's improved serving and consistency in the middle stages proved decisive. The tight final set reflected the quality of both players, yet Cilic's experience in high-pressure Davis Cup moments ultimately made the difference. The result advances Cilic deeper into the Finals and maintains his bid for team success in the competition's knockout stages.
