• Cameron Norrie defeats Carlos Alcaraz 4-6 6-3 6-4 at the Paris Masters.
• The victory ends Alcaraz's 17-match winning streak at ATP Masters level.
• Norrie's win is his first over a world number one, marking a significant career milestone.

Britain's Cameron Norrie stunned world number one Carlos Alcaraz by coming back from a set down to win 4-6 6-3 6-4 in the second round of the Paris Masters. This victory propels Norrie into the last 16 of the ATP Masters 1,000 event for the first time since 2023 in Rome, matching his best previous showing in Paris from 2021. Alcaraz's defeat ends his 17-match winning streak at the Masters level, a run that included titles in Monte Carlo, Rome, and Cincinnati, according to BBC, Reuters, and Al Jazeera.

Norrie, who had been recovering from an injury, expressed profound joy over the win, stating, "Massive (victory), so big for me," reflecting on his progress and resilience. Despite winning the first set, Alcaraz struggled with his performance, committing 54 unforced errors, and showed signs of frustration during the match. This loss is particularly significant as it marks the first time Alcaraz has failed to reach a final since March, according to Reuters and BBC.

Norrie will next face either Valentin Vacherot or Arthur Rinderknech, who are set to play in a rematch of the Shanghai Masters final. Alcaraz's recent loss puts him at risk of losing his year-end world number one ranking if Jannik Sinner captures the Paris title this week, further intensifying the competition among top players, according to Al Jazeera and Reuters.
