Carlos Alcaraz has moved ahead of Jannik Sinner in the ATP Live Rankings as the US Open advances, while a number of players have gained or lost ground following results through the fourth round. Sinner remains No 1 in the official ATP Rankings, but the Live Rankings reflect points dropping from corresponding events 12 months earlier. The Italian lost 2,000 points after being crowned 2024 champion in New York, while Alcaraz lost only 50 points after a second-round exit last year. That swing leaves Alcaraz ahead and able to stay there if he outperforms Sinner at Flushing Meadows.

Current ATP top 10 (Before US Open):
1. Jannik Sinner – 11,480
2. Carlos Alcaraz – 9,590
3. Alexander Zverev – 6,230
4. Taylor Fritz – 5,575
5. Jack Draper – 4,440
6. Ben Shelton – 4,280
7. Novak Djokovic – 4,130
8. Alex de Minaur – 3,545
9. Karen Khachanov – 3,240
10. Lorenzo Musetti – 3,205

Alcaraz has already reached the quarter-final after defeating Arthur Rinderknech in straight sets in the fourth round, and he is yet to drop a set in the tournament. Sinner still has a last-16 match to play. World No 3 Alexander Zverev has exited the US Open and faces a potential slip in the Live Rankings; Taylor Fritz and Novak Djokovic would have to win the title to pass him.

Fritz and Djokovic meet in the quarter-final, with the winner to play either Alcaraz or Jiri Lehecka. Fritz was in danger of losing the American No 1 ranking to Ben Shelton after the tournament, but the sixth seed’s third-round retirement put an end to that battle. Fritz’s record against Djokovic stands at 0-10.

Djokovic began this sequence at No 7 and has climbed two places to No 5. A related Live projection lists:
1. Carlos Alcaraz – 9,940
2. Jannik Sinner – 9,680
3. Alexander Zverev – 5,930
4. Taylor Fritz – 4,675
5. Novak Djokovic – 4,430

Elsewhere, Jiri Lehecka has reached his first US Open quarter-final and is up six places to No 15, three spots ahead of Alexander Bublik who is up six. Felix Auger-Aliassime is projected to rise seven places to No 20 after defeating Zverev. Adrian Mannarino is +22 to No 55, Arthur Rinderknech is two spots below him after jumping 25 places, and Kamil Majchrzak becomes the new Polish No 1 at No 62 (+14). Jan Lennard Struff is up 46 places to No 98. Leandro Riedi is the biggest mover at +271 to No 164 with a career best of 117. Daniil Medvedev is down four places to No 17. Frances Tiafoe is projected to drop 12 places to No 29 and Jordan Thompson is set to slip 19 spots to No 57. Holger Rune (11) and Casper Ruud (12) retain their positions while Stefanos Tsitsipas is up one to No 27.

Novak Djokovic added another entry to an already long list of Grand Slam milestones after a routine fourth-round win at the US Open moved him ahead of Roger Federer in a specific men’s singles record. The 24-time major champion defeated German qualifier Jan-Lennard Struff 6-3, 6-3, 6-2 at Flushing Meadows to secure a ninth season in which he has reached the quarter-finals at all four Slams.

Djokovic and Federer had been level on eight seasons for that achievement. Djokovic previously completed the set in 2010, 2011, 2012, 2013, 2014, 2015, 2021 and 2023; Federer’s run came from 2005 to 2012. In each of those eight seasons Djokovic won at least one Grand Slam, a pattern that underlines the significance of the statistic, although he is yet to claim a major since his 2023 US Open title.

At 38 years and 94 days, Djokovic also became the fourth-oldest man to reach the US Open quarter-finals, behind Pancho Gonzalez (40), Ken Rosewall (39) and Jimmy Connors (39). Reflecting on Connors’ 1991 run, Djokovic said: “I remember that [Connors 1991] run. I was very, very young, so I don’t vividly remember it when it was happening,” he explained. “But in the years to come when I was growing up watching a lot of tennis, everyone was talking about that run being one of the most historic runs we had in the sport at any Slam.

“Jimmy Connors being one of the greatest tennis players of all time, greatest legends in general overall globally, but particularly in this tournament. He’s won it five times? He’s fired up the New York crowd like no other player has done in his career.

“Just being in the same discussion or same conversation with Jimmy is obviously a huge honour of mine.”

Djokovic now prepares to face fourth seed Taylor Fritz in the quarter-final as he chases a record-extending 53 Grand Slam semi-final. He holds a 10-0 head-to-head advantage over Fritz, their most recent meeting coming in the semi-final of the 2024 Shanghai Masters, which Djokovic won in straight sets. By reaching this US Open quarter-final Djokovic will rise two places to return to No 5 in the ATP Rankings, with Jannik Sinner, Carlos Alcaraz, Alexander Zverev and Fritz ahead of him. A semi-final would move him past Fritz, while a title run would lift him to No 3.

Novak Djokovic moved into his record 64th Grand Slam quarterfinal after a straight-sets victory over qualifier Jan-Lennard Struff, winning 6-3, 6-3, 6-2. The 38-year-old, a 24-time major champion, appeared to be in control early but felt a twinge in his neck midway through the opening set.

Djokovic was up 4-0, 15-love when he hit an angled volley to make it 30-love and immediately grabbed the back of his neck, turning his head. He continued to stretch his neck and flex his right shoulder between points and dropped that game and the next before regaining command of the match.

Struff, the 144th-ranked qualifier who had beaten Frances Tiafoe in the previous round, was seeking his first major quarterfinal. Djokovic improved to 8-0 against Struff with the win.

After closing out the first set, Djokovic received treatment from a trainer during the changeover, including a massage to his neck and shoulder. He also had his right forearm massaged during the subsequent break. Earlier in the tournament, trainers had treated him for blisters on a foot in the first round and for a lower-back issue in the third.

Djokovic’s health issues did not visibly affect his play once points were in progress, and he finished the match without further incident. He now heads into a quarterfinal scheduled for Tuesday against 2024 US Open runner-up Taylor Fritz.

Fritz, the No. 4 seed and the last American man remaining in the draw, reached the quarterfinals with a 6-4, 6-3, 6-3 victory Sunday over No. 21 Tomas Machac of the Czech Republic. Djokovic will carry a 10-0 head-to-head record into that quarterfinal encounter.
