Stéfanos Tsitsipás defeated Arthur Rinderknech 7–5, 6–3 in the first round of the ATP 250 Rotterdam tournament on hard court. As the pre-match favourite with odds of 1.54, Tsitsipás delivered a straightforward performance to advance, controlling both sets with consistent play. Rinderknech, positioned as the underdog at 2.47, was unable to sustain competitive pressure, particularly in the second set where the Greek player's dominance became pronounced. The victory extends Tsitsipás's early-season form at Rotterdam and positions him favourably for the tournament's latter stages.
