Ethan Quinn upset Hubert Hurkacz 6–2, 6–4 in the first round of the Miami Masters on hard court, claiming a significant victory against the pre-match favourite. Despite Hurkacz entering as the betting favourite at 1.69 odds to Quinn's 2.13, the American dominated the opening set and maintained control throughout, breaking serve decisively in both sets to secure a comprehensive two-set victory. The result represents a notable scalp for Quinn at a Masters 1000 event and suggests improved form heading into the latter stages of the hard-court season.
