After losing the opening set, Alcaraz regrouped decisively, taking control in the second and third sets to advance to the final. The Spaniard's recovery from a set down demonstrated the consistency required at this level, whilst Ruud, despite a strong start, was unable to sustain the intensity needed to upset the odds. This victory positions Alcaraz within striking distance of the Tokyo title and reinforces his standing among the tour's elite performers.
