Until the generational talents walked onto Court Rainier III, Alcaraz led their riveting rivalry at 10-6 and had won his past 17 clay-court matches, which dated back to Rome Masters and Roland-Garros finals glory over Sinner.
Could seven-time Grand Slam champion Alcaraz retain his Monte-Carlo crown?
Well, Sinner arrived in the final on a 21-match Masters 1000 winning streak, following title runs in Paris (2025), Indian Wells and Miami, without dropping a set in all three banner events.
The stakes were as high as possible, with Masters silverware and the world No.1 ranking on offer for the champion.
The swirling wind provided challenging conditions, yet ‘Sincaraz’ still managed to put on quite the show. The absorbing clash seemed destined for a decider at 3-1 second set in the Spaniard’s favour. Then Sinner elevated his game – connecting with a catalogue of piercing shots and demonstrating his supreme anticipation to stay one step of his rival to rattle through the final five games for a 7-6(5), 6-3 scoreboard.
"It has been an interesting week trying to learn how to play again on clay," said a modest Sinner, shortly after his 27th ATP title victory and opening event on clay this year.
