Sinner reclaims No. 1

Jannik Sinner left Monte Carlo with two prizes on Sunday: the title and the top spot in men’s tennis. (atptour.com) Sinner beat Carlos Alcaraz 7-6 (5), 6-3 in the Rolex Monte-Carlo Masters final, a match that lasted 2 hours, 15 minutes in windy conditions. The win gave the 24-year-old Italian his first clay-court ATP Masters 1000 title and his eighth at that level overall. (atptour.com) The ATP rankings released on Monday put Sinner back at No. 1 with 13,350 points, 110 ahead of Alcaraz on 13,240. Alcaraz, 22, had entered Monte Carlo as the top-ranked player. (atptour.com) Monte Carlo also changed the season-long standings. ATP Tour said on April 13 that Sinner moved into first place in the Race to Turin, the points table that tracks the calendar year and determines the eight-player field for the ATP Finals in November. (atptour.com) That shift came after a fast start to 2026. ATP Tour said Sinner completed the “Sunshine Double” by winning Indian Wells and Miami before adding Monte Carlo, while Alcaraz had opened the year by building a lead in the rankings race. (atptour.com) The Monte Carlo final was their first meeting of the 2026 season, and it resumed a rivalry that had already been unusually tight by several measures. ATP Tour noted before the match that Alcaraz led the head-to-head 10-6, while both men had each spent 66 weeks at No. 1. (atptour.com) The tournament carried extra weight because the rankings math was simple. ATP Tour wrote before the final that if Sinner won the title, he was guaranteed to return to No. 1 regardless of Alcaraz’s result. (atptour.com) Post-match coverage focused on how Sinner handled a messy final better than Alcaraz. ATP Tour described the match as being played in windy conditions, and Alcaraz said afterward that he “didn't play well in the big moments” against Sinner. (atptour.com 1) (atptour.com 2) The result also extended Sinner’s run at the biggest events. ATP Tour said Monte Carlo was his third ATP Masters 1000 title of 2026 and his 14th “Big Title,” a category that includes Grand Slams, the ATP Finals, Masters 1000 events and Olympic singles gold. (atptour.com) The clay season now moves on with Sinner back on top in both the weekly rankings and the 2026 race. After one afternoon in Monte Carlo, the gap between the two leading men narrowed to 110 ranking points and widened into the next chapter of their rivalry. (atptour.com 1) (atptour.com 2)
