Alcaraz Significantly Cuts Sinner's No. 1 Lead, Medvedev & Rune Fall In ATP Rankings

Carlos Alcaraz could regain the ATP No. 1 ranking in a few weeks after reducing Jannik Sinner's lead at the top.

Sinner has been the No. 1 for over 14 months, overtaking Novak Djokovic in June 2024. After winning the 2025 Australian Open, he had built a massive lead and was already a heavy favorite to finish as the year-end No. 1.

However, Sinner's three-month suspension from February until a few days before May's Italian Open allowed Alcaraz and Alexander Zverev to close the gap, but they missed their chance to overtake Sinner during his absence.

After a poor March, Alcaraz has moved close to his rival in the rankings with superb results since April, including winning the French Open, Monte-Carlo Masters, Italian Open, Queen's Club Championships, and Cincinnati Open after Sinner's retirement in the opening set.

That meant Sinner failed to defend the title he won last year in Cincinnati, meaning his points total is 550 lower than before the tournament. The four-time Grand Slam champion is still at No. 1 with 11,480 points.

Alcaraz, who lost to Gael Monfils in the 2024 opening round, gained 1,000 points for securing a maiden Cincinnati Open crown. That took his total to 9,590, putting him within 2,000 of Sinner.

The Spaniard can mathematically become No. 1 after the US Open. Sinner will defend 2,000 points from winning last year's men's singles at Flushing Meadows, while Alcaraz was stunned almost 12 months ago by Botic van de Zandschulp in the second round.

Karen Khachanov was the only new entrant into the Top 10. He reached the round of 16 in Cincinnati, backing up finishing as the runner-up in Toronto with another solid result. That allowed him to jump three spots to No. 9.

Alexander Zverev at No. 3, Taylor Fritz at No. 4, Jack Draper at No. 5, Ben Shelton at No. 6, Novak Djokovic at No. 7, Alex de Minaur at No. 8, and Lorenzo Musetti at No. 10 are unchanged in the rankings.

Holger Rune was the sole man to drop out of the Top 10, slipping to No. 11. The Dane's good run to the Cincinnati Open quarterfinal, which was ended by Terence Atmane, could not prevent him from falling.

Despite early exits at the Canadian Open and Cincinnati Open, Daniil Medvedev climbed two positions to No. 13. That is still lower than the world No. 1 has been accustomed to in the last few years.

Frances Tiafoe's failure to match his final run in Cincinnati last year meant he plummeted three places to No. 17. The 2022 and 2024 US Open semifinalist will hope he peaks at Flushing Meadows and secures a maiden Grand Slam.

Teenage star Joao Fonseca is at a career high and in the Top 50 after rising to No. 44. The Brazilian receives incredible support worldwide and could have a deep US Open run if he plays his best tennis.

Andrey Rublev dropping to No. 15, Francisco Cerundolo entering the Top 20 at No. 19, and Grigor Dimitrov falling to No. 25 are among the other changes to the ATP rankings.
