Game context
Felix Auger-Aliassime enters as the higher-ranked player and No. 2 seed but carries uncertainty after withdrawing from Montreal with a back injury and not playing since Wimbledon. Stefanos Tsitsipas arrives with recent match rhythm, including a Gstaad title and a straight-sets Cincinnati opener, plus a strong 7-3 head-to-head edge that includes a 2025 Dubai final win and favorable hard-court results. The outdoor hard-court matchup pits Tsitsipas’ current form and direct-experience advantage against Auger-Aliassime’s superior ranking and talent when healthy. Resolution hinges on whether the Canadian’s layoff affects movement and consistency or if his baseline power prevails in what shapes up as a competitive early-round encounter.
