Reilly Opelka topped Christopher Eubanks 6-3, 7-6 (4) in an all-American first-round matchup on Thursday at the Miami Open. Opelka, who's playing on a protected ranking as he works his way back from hip and wrist injuries that sidelined him in 2023 and 2024, earned his first match win at an ATP Masters 1000 event since 2022.
