Karolína Muchová upset favourite Elena Rybakina 6–2, 2–6, 6–4 in the quarter-final of the Brisbane WTA 250 on hard court. Rybakina entered as the odds-on favourite at 1.26, with Muchová priced at 4.29, yet the Czech player delivered a composed performance to claim victory in three sets. After losing the opening set decisively, Muchová levelled the match with a commanding second set before seizing control in the decider to secure her place in the semi-finals. The comeback victory demonstrates Muchová's ability to read and adapt to her opponent's game, particularly after a sluggish start. This result significantly boosts Muchová's Brisbane campaign and marks a notable scalp against a top-ranked opponent.
