Talia Gibson defeated Naomi Osaka 7–5, 6–4 in the first round of the Miami Masters on hard court, delivering a significant upset against the pre-match favourite. Gibson, trading at 2.73 odds, outperformed expectations to claim victory over Osaka, who entered as the 1.43 favourite. The American's composed performance across both sets proved sufficient to overcome her higher-ranked opponent in straight sets. Gibson's maiden Masters 1000 win at this stage represents a notable statement of intent, whilst Osaka's early exit marks a disappointing result at one of the circuit's premier events.
