Stéfanos Tsitsipás defeated Reilly Opelka 6–2, 6–2 in the first round of the ATP 250 Barcelona tournament on clay on 15 April 2025, confirming his status as the clear pre-match favourite with odds of 1.16 against Opelka's 6.13. The Greek player's commanding performance on the surface highlighted the mismatch between a clay-court specialist and an opponent whose game is better suited to faster courts. Tsitsipás's clinical execution across both sets underlined his comfort in Barcelona, where the conditions favour his baseline game. The result maintains Tsitsipás's strong clay-court form heading into the European spring season.
