For the second time in seven months, Jannik Sinner and Carlos Alcaraz met in a final with the world No. 1 ranking on the line.
After Alcaraz triumphed at the 2025 US Open to knock Sinner off his perch, the Italian reclaimed the top spot with a 7-6(5), 6-3 result Sunday at the Monte Carlo ATP Masters 1000. Adding to the significance: Both men had spent a total of 66 weeks at No. 1 entering the final, with Sinner now edging ahead in the overall count with his 67th week at the summit.
"Getting back to No. 1 means a lot for me," said the Italian, who is now enjoying his third stint as the ATP's leading man, including a one-week stay in November.
Sinner stormed ahead of his rival by claiming three consecutive ATP Masters 1000 crowns, losing just one set in 17 match wins across Indian Wells, Miami and Monte Carlo. The three titles also take Sinner's trophy tally to 27, moving him ahead of Alcaraz on 26.
US Open champion in 2024, Sinner has won 14 hard-court titles since 2024. While he was one point away from the ultimate clay crown last year at Roland Garros, where he famously missed out on three match points against Alcaraz, the Italian only had one clay title to his name prior to Monaco: a 2022 triumph at the ATP 250 in Umag.
"I am very happy to win a big title on this surface. I haven't done it before and it means a lot to me," said Sinner, who admitted to being pleasantly surprised with his success.
After losing to Alcaraz at the US Open, Sinner discussed the importance of adding variety and unpredictability to his game in order to keep pace with his rival. Though Alcaraz still leads the pair's head-to-head, 10-7, Sinner has now won two straight matches against his rival. His wins on the indoor hard courts of the 2025 ATP Finals and the outdoor clay of Monte Carlo showcase Sinner's evolution into a more versatile and complete player.
But Sinner's position at No. 1 is immediately under threat. With Sinner idle, Alcaraz could wrestle back the top spot by winning the ATP 500 in Barcelona.
