Matteo Berrettini of Italy caused a huge upset in the Qatar Open 2025, beating former World No.1 Novak Djokovic in straight sets in a first-round match at the ATP 500 series event being played on the hard courts here on Tuesday. This is Berrettini's first top-10 win since 2023. 

Berrettini, who is currently ranked 35th in the ATP Rankings and had a career-high rank of 6 in January 2022, survived a few anxious moments, including a couple of break points in the sixth game of the first set, before winning the match 7-6(4), 6-2 in one hour and 33 minutes. While Berrettini is unseeded here, Djokovic is the third seed and was expected to go all the way after retiring from his Australian Open semi-final against Alexander Zverev with a hamstring injury last month. However, the Italian had other ideas as he served a potent display of power tennis to upset the 24-time Grand Slam winner.
