ANALYSIS: Where does Jannik Sinner's 21-match indoor hardcourt unbeaten streak rank amongst the longest in the Open Era

Jannik Sinner goes into the 2025 Paris Masters not yet having won a Masters 1000 tournament in 2025. This is his last chance to, and all the signs are pointing towards triumph, with him traversing to the French capital with a 21-match unbeaten streak on indoor hardcourts.

His last defeat in this setting came in the Davis Cup back in 2023. He has then gone on to sweep anyone aside who dares to challenge him. This run includes big titles like the 2024 ATP Finals where he did not even drop a set enroute to victory, before helping his country win a second successive Davis Cup. He also cashed in at the Six Kings Slam, winning the previous two editions while beating Carlos Alcaraz in the final on both occasions. Most recently, he stormed to glory in the Vienna Open, not dropping a set until he faced world number three Alexander Zverev in the final, where he fought back from a one-set deficit to clinch his second title in Austria.

With two tournaments remaining of the Italian in 2025, he has the chance to extend this incredible winning streak if he tastes victory in the Paris Masters and ATP Finals. If he wins both events, another 10 victories can be added to his current tally. However, this would only be the fifth longest indoor hardcourt winning streak recorded, with work to do if he wants to surpass some of the greats.

At the top of the list sits John McEnroe. Now, if you thought Sinner's current string of wins was good, it is nowhere near what the American produced between 1978-1987. If Sinner goes on to win another 21 matches, he will still be five behind McEnroe's 47 consecutive triumphs. This is celebrated as an incredible record that may never get beaten, although some have tried.

His closest compatriot was Novak Djokovic, who racked up 35 wins on the bounce between 2012-2015. This streak included three Paris Masters titles on the bounce and three ATP Finals triumphs, with his fourth successive title coming after losing his streak to Roger Federer in the group phase. Coincidently, it is the Swiss star who is next on the list, with his best coming in between 2004 and 2007, finishing up with 33 wins on the spin. He almost replicated this feat between 2009-2012, but this time falling short with 29 consecutive victories. Separating these two runs from the 20-time Grand Slam champion is Ivan Lendl, who sits on 32. He is in danger of getting surpassed by Sinner, with the Italian able to close within a single win of the former world number one final count.

Pete Sampras's 25 (1996-1997) and Stefan Edberg's 21 (1986-1988) are the only other players who for now can say they have a longer win streak than Sinner although Edberg's bragging rights may fall to a hush if the 24-year-old pulls out one more win. The Vienna Open win did take the four-time Grand Slam champion ahead of Andy Murray, who recorded 20 wins in a row between 2016-2019. This started with him winning the ATP Finals and becoming number one in the world, before injuries derailed his career and prevented him from extending his winning streak on the surface.

Sinner can make it 22 in his opening match in the Paris Masters, with a clash against either world number 34 Alex Michelsen or Belgian star Zizou Bergs. The chances of meeting his old foe Alcaraz in the final is looking likely once more, with the pair continuing their dominance on the ATP circuit.
