Medjedovic, listed at 2.72 odds, was a clear underdog against Tsitsipás, who entered as the 1.51 favourite, yet the Bosnian delivered a composed performance across three tight sets to secure the upset victory. The match remained closely contested throughout, with both players trading breaks and holding serve in crucial moments, ultimately decided in tiebreaks in the first and third sets.
