This loss marks Djokovic’s first opening-round exit since Monte-Carlo 2022 and raises questions about his ability to withstand the new generation of aggressive and fearless players.

Italian Matteo Berrettini upset third-seeded Novak Djokovic 7-6 (4), 6-2 in the first round of the Qatar ExxonMobil Open in Doha on Tuesday. It was the first career win in five attempts for Berrettini against the Serbian and also his first victory over a top-10 player since 2023.
