Jannik Sinner stuns Novak Djokovic to break Serb's stranglehold on Australian Open

The 22-year-old Italian was seen as the most likely rival to stop Djokovic claiming an 11th title in Melbourne ahead of the tournament after beating him twice in two weeks at the end of last season at the ATP Finals and Davis Cup.

But surely no one would have predicted the manner of the first two sets of this semi-final, with an error-strewn Djokovic winning just three games.

He saved a match point in the third-set tie-break to give himself hope but there was no dramatic comeback, with Sinner regrouping impressively and going on to clinch a 6-1 6-2 6-7 (6) 6-3 victory after three hours and 22 minutes.

Sinner said: "It was a very, very tough match. I started off really well, he missed for two sets, I felt like he was not feeling that great on court. I just tried to keep pushing.

"In the third set I had match point, I had the forehand which I missed but that’s tennis. I just tried to be ready for the fourth set.

"I was looking forward for this match. It’s always nice to have this kind of player where you can learn from. I lost last year in the semis at Wimbledon and I learned a lot from that match.

"The confidence from end of last year has for sure kept the belief that I can play against the best players in the world. I’m really happy that I can play my first final and let’s see how it goes."

The fourth seed moves through to a first grand slam final while Djokovic, who had not lost here since a fourth-round defeat by Hyeon Chung amid elbow problems in 2018, must lick his wounds, with a record 25th slam title proving beyond him for now.

The result was, of course, a shock given Djokovic's incredible record here – this is the first time he has ever lost having made it beyond the quarter-finals – but it was the Serbian's display that was the most surprising.

He committed 54 unforced errors and did not even make Sinner use his haymaker groundstrokes that often, the Italian instead able to maintain a very high but comfortable level and not facing a single break point.

Djokovic struggled with illness at the start of the fortnight and had a tougher passage through to the last four than usual, losing three sets along the way.

Sinner, the first Italian to make an Australian Open singles final, had not dropped a set all tournament, and he started as he meant to go on, breaking the Djokovic serve to lead 2-0 with a searing forehand followed by a drive volley winner.

By contrast, nothing was working for Djokovic, with routine shots landing in the net or out of court, while he was also struggling on serve.

Sinner broke again to lead 5-1 and wrapped up the first set with just over half an hour gone.

Djokovic is a master at pacing himself in best-of-five-sets tennis and he would certainly not have panicked having lost only two of the last 17 slam matches in which he dropped the first set.

But the pattern of the match continued in the same vein, with more Djokovic errors helping Sinner break for 2-1 in the second set.

Djokovic whipped up crowd support after saving a break point at 2-4 in fine style but Sinner broke anyway two points later and served out the set.

Two years ago at Wimbledon, Sinner led Djokovic by two sets to love only to lose in five, so he knew very well that the match was far from over.

Djokovic, who had barely showed any emotion, clenched his fist after saving a break point in the opening game of the third set, and he at least managed to serve better.

At 5-5 and deuce on the Serbian's serve, a medical emergency in the crowd forced a delay for several minutes, but Djokovic held his nerve on the resumption.

The world number one knew it was now or never in the tie-break, and he opened up a 4-2 lead, but Sinner surged back, creating a match point at 6-5 but netting a forehand, and a backhand over the baseline two points later gave Djokovic a lifeline.

He was still hanging on, though, saving three break points in the second game of the fourth set only to then be broken from 40-0 two games later.

Djokovic forced Sinner to serve it out but the Italian did not waver, clinching the biggest win of his life with a forehand winner.
