Alexander Zverev will not face disciplinary action from the ATP following its investigation into allegations of domestic abuse against him.

The two-time ATP Finals winner became the subject of an investigation in October 2021 after claims the prior year by ex-partner Olya Sharypova.

The sport's governing body hired an external private investigation company to look into the allegations, which Zverev has denied.

Now, after it was deemed there was "insufficient evidence" to substantiate the claims, it has been confirmed the German will face no further action.

"Based on a lack of reliable evidence and eyewitness reports, in addition to conflicting statements by Sharypova, Zverev and other interviewees, the investigation was unable to substantiate the allegations of abuse," the ATP said.

While no action is to be taken, the ATP added it would reevaluate its decision "should new evidence come to light, or should any legal proceedings reveal violations of ATP rules".

Zverev, who reached the 2020 US Open final and won men's singles gold at the Tokyo 2020 Olympics, achieved a career-best peak of number two in the world rankings last season.

An ankle injury at the French Open against Rafael Nadal ended his campaign and he only made his return to competitive action earlier this month, with a second-round exit at the Australian Open.

He took further legal action against Sharypova last year, as well as an online publisher, after further allegations of abuse were made, while lending his support for a domestic violence policy to be introduced by the ATP.

Cameron Norrie is hoping Russian players will be allowed to return to Wimbledon in 2023, saying he wants "the best players in the world to be playing".

Following the Russian invasion of Ukraine earlier this year, Russian players were banned from participating at SW19.

This meant the likes of Daniil Medvedev and Andrey Rublev were not able to play and compete for the third grand slam of the year, which Novak Djokovic ended up winning for the seventh time.

The tournament was stripped of ranking points as a result of the ban on Russians, a decision that was met with much frustration from players.

Medvedev and Rublev finished a respective seventh and eighth in the year-end ATP rankings, and both took part in the ATP Finals in Turin.

Norrie hopes they are able to return to Wimbledon next year, telling reporters: "For me, I want the best players in the world to be playing.

"I felt last year was tough for those guys, especially for Daniil and for Andrey, who have a chance of winning Wimbledon.

"I know how much those guys sacrificed with their careers and their goals are obviously very high to be winning Slams.

"So I really did feel bad for those guys."

Carlos Alcaraz turns a "deaf ear" to comparisons between himself and fellow Spaniard Rafael Nadal.

A stunning season for Alcaraz has seen him become the youngest world number one in ATP history at the age of 19.

He won two Masters 1000 titles and his maiden grand slam at the US Open in September.

Alcaraz was ruled out of the ATP Finals with an abdominal injury, but Nadal's elimination in Turin ensured Alcaraz would end 2022 as the youngest ever year-end number one.

Such accomplishments have seen him compared by some to countryman Nadal, who won the French Open aged just 19 in 2005 on his way to becoming one of the most decorated men's tennis players of all time.

But Alcaraz refuses to entertain such talk, instead speaking of his admiration at what the now 36-year-old Nadal had achieved over his long career.

"There is no point in comparing," Alcaraz told reporters. "It doesn't matter that now I am world number one, Rafa's entire career counts for a lot.

"It is a pleasure, for every tennis lover, to see Rafa on the court."

He added he hopes to achieve "at least half" of what Nadal has, in a career spanning over two decades and encompassing 22 grand slam titles.

Alcaraz, meanwhile, is trying to "regain strength before returning to the court" as he eyes the new season, and acknowledged he will start with a target on his back due to his 2022 success.

"The season is going to be difficult because I am going to start as the favourite," he explained. "There is going to be a lot of pressure on me.

"But I try to keep the good part and see that all this does not go to my head. In the end, beating your idols is an incredible achievement.

"I try to take it normally and never forget that whatever happens in the future, I have to enjoy tennis and play at my level."

Novak Djokovic has no doubt in his own mind he is the best tennis player in the world, regardless of what the rankings say.

After clinching a record-equalling sixth ATP Finals title by downing Casper Ruud in Turin, Djokovic reflected on a turbulent 2022 season in which he was unable to play in two of the four grand slam events.

His refusal to accept a COVID-19 vaccination meant Djokovic was denied permission to compete at the Australian Open and US Open, while the various tennis authorities' reaction to the Ukraine crisis meant no ranking points were on offer at Wimbledon.

Indeed, Djokovic successfully defended his title at the All England Club, but in doing so he lost all of his 2,000 points for being the 2021 champion.

As such, he entered the ATP Finals as the world number eight, with his unbeaten run at the tournament seeing him collect 1,500 points and jump up to fifth on the ATP ranking list.

Carlos Alcaraz is the number one for now, after a stellar season for the 19-year-old Spaniard in which the highlight was his US Open victory, but Djokovic will be the favourite with many for the Australian Open, with authorities expected to allow him to play next year.

Asked if he was the world's best player, Djokovic said: "I'm not. I'm fifth."

That came with a smile from the Serbian, who added: "This week I probably am [the best]. Overall the rankings are showing who had the best year, and Alcaraz is the number one in the world. Not much to say about that.

"But in my mind I always see myself as the best player in the world, of course. I have that kind of mentality and that kind of approach. Regardless of who is across the net, regardless of what the surface is, regardless of what season it is, what number of the professional season in my career we're facing, I mean, it's always the same. The ambitions are as high as possible.

"That kind of approach, I feel it brought me to where I am sitting here today as a 35-year-old, holding one of the biggest trophies in the sport."

The 21-time grand slam winner, one behind Rafael Nadal on the men's all-time singles list, said the prospects for future success come down to his "love and passion" for tennis.

"As long as that's there I'll do anything in my power to challenge the young guys for the biggest trophies," Djokovic said.

"I don't know what the future holds, but I know that what I hold in my mind is a huge hunger still to win trophies, make history of this sport, compete on the highest level all around the world, bring good emotions to sports fans, tennis fans."

Djokovic was greeted after the final by Milan striker Zlatan Ibrahimovic, another sporting evergreen at the age of 41, albeit very much in his career twilight.

The same cannot be said yet for Djokovic, who may have several seasons left at this high level.

His coach, former Wimbledon champion Goran Ivanisevic, watched on admiringly as Djokovic won 7-5 6-3 in Turin against Ruud on Sunday.

According to Croatian Ivanisevic, the key to Djokovic's success in his mid-thirties is his relentless work rate.

"He's practising even harder than when he was 22," said Ivanisevic. "That's why he's still so good and that's why he's still going to be even better.

"The will to practise, the will to improve, the will to be better is amazing. He's taking care of his body. In my time we stopped tennis at 30, 31. You were already an old guy ready to leave.

"They all talk about, yes, young players are coming. It's great for tennis. You have the youngest number one in the world who made unbelievable things this year, Carlos. But look at Novak. He's still hungry, he's still winning the tournament, playing unbelievable tennis. He's still already thinking now about preparation for next season.

"Till he's like that, in his mind he's going to be always competitive, favourite to win majors and the big tournaments."

Novak Djokovic ended his "roller coaster year" on a roaring high with victory at the ATP Finals, matching Roger Federer's record of six titles by sinking the hopes of Casper Ruud.

The Serbian said he had spent the season "on the needles", his colourful way of describing the nervousness and discomfort he had experienced during a campaign which saw him prevented from playing in Australia and North America.

Djokovic, who has refused to take a COVID-19 vaccination, has seen his career suffer because of that firm stance. He was thrown out of Australia in January, a humiliating way to begin the year.

Yet there is little doubting the 35-year-old remains the pre-eminent player on tour heading towards the 2023 season, even with the rise of Carlos Alcaraz, who ends the year as world number one.

A first ATP Finals triumph for Djokovic came in 2008, and he then won four in a row from 2012 to 2015, and now he has carried off the trophy once more, plus a cheque worth $4.74million, the biggest prize ever paid out in tennis.

"Seven years, it's been a long time. At the same time, the fact I've waited seven years makes this victory even sweeter and even bigger," Djokovic said.

Speaking on Amazon Prime, Djokovic said the win after all he has gone through felt "huge".

"I probably talked about this season and how unusual it is 1,000 times prior to this interview, so I'm not going to repeat what most people who follow tennis know," he said.

"[It's] just a big relief and satisfaction, and also I look forward to having a couple of weeks off, because I've been on the needles the entire year, whether for tournaments or waiting for permissions to go somewhere, so I'm really glad I managed to end it in a positive way."

He is the oldest champion in the tournament's 53-year history, breaking a record held by Federer, who was 30 when he won in 2011.

Djokovic said it was "really, really impressive" for Ruud to have reached grand slam finals in Paris and New York, and the ATP Finals title match, in a stellar year for the 23-year-old Norwegian.

But Djokovic was ruthless in Sunday's final, emerging a 7-5 6-3 winner thanks to a break of serve in each set, earning a fifth title of his disrupted year following wins at Wimbledon, Rome, Astana and Tel Aviv.

Thanking his team and supporters during the trophy presentation for "going through some tough times" with him, Djokovic said there were moments where he had needed "a shoulder to lean on, a shoulder to cry on".

The 21-time grand slam winner added: "It's been a roller coaster year really, something I've never experienced ever before in my life, and only we know what we've been through."

Novak Djokovic ended his tumultuous year on a breathtaking high by dismantling Casper Ruud to win the title match at the ATP Finals, pocketing almost $5million in the process.

The man who was deported from Australia after a vaccination and visa dispute in January, then refused entry to the United States later in the campaign, scorched to a 7-5 6-3 victory against rising star Ruud.

This was a sixth triumph for Djokovic at the ATP Finals, matching Roger Federer's record, and at the age of 35 he is also the oldest champion at the event. Federer was previously the oldest, being 30 when he captured the 2011 title in London.

The tournament has since moved to Turin, and Djokovic reels in $4.74million for a victory that shows he remains the player to beat, wherever and whenever he gets the chance to play.

Serbian superstar Djokovic had two chances to break in the second game but Ruud resisted, and the younger man saved another break point in the eighth game too, but a further opportunity came at 6-5 after Ruud paddled a backhand into the net. The 23-year-old Norwegian sent the ball long in the next rally to slip behind.

It was becoming a masterclass from Djokovic and he was pummelling the ball from the back of the court, breaking Ruud's serve for a 3-1 lead in the second set. Djokovic later won a 36-shot rally to set up championship point, sealing victory with an ace down the centre.

Ruud, a runner-up this season at the French Open and US Open, had watched each of Djokovic's previous ATP Finals victories on television, and this time he had a prime spot to witness the 21-time grand slam winner at the top of his game.

Try as he might, Ruud could not find a way to fight back once the stranglehold was with Djokovic, who heads towards 2023 with his appetite for the biggest trophies in tennis far from sated.

Casper Ruud swept through to a showdown with Novak Djokovic at the ATP Finals, making light work of Andrey Rublev to reach the trophy match.

The 23-year-old Norwegian has enjoyed a stunning season, reaching two grand slam finals, and his 6-2 6-4 semi-final dismissal of Russian Rublev was impressively authoritative.

After Ruud coasted through the opening set, the occasion fell wholly flat when Ruud broke serve in the first game of the second, and did so again in the third game.

Rublev sat shaking his head at his chair in the break between games, also shrugging his shoulders towards his support team and looking lost for ideas.

He only began to make an impact after slipping 4-0 behind, and at 5-2 he broke Ruud's serve to narrow the gap and give the Turin crowd hope the contest could take off.

At 5-4, it was briefly tense, but Ruud served for the match for a second time and this time made it count, sealing victory with a brilliant backhand winner to become the first Scandinavian finalist at the ATP Finals since Stefan Edberg in 1990.

Ruud will overtake Rafael Nadal and end the year at number two in the ATP rankings should he carry off the title on Sunday; however, he has a 0-3 career record against Djokovic. Djokovic earlier battled past Taylor Fritz by winning a pair of tight tie-breaks to earn a straight-sets victory in the first of Saturday's semi-finals.

Novak Djokovic sealed his place in the final of the ATP Finals after edging past Taylor Fritz 7-6 (7-5) 7-6 (8-6) in Turin on Saturday.

The Serbian, who is bidding to equal Roger Federer's record of six ATP Finals titles, overcame Daniil Medvedev in a bruising three-hour contest on Friday, and he was again made to work hard for victory against spirited American Fritz.

Djokovic struck first in the opening set with a break to love in the fifth game, yet Fritz responded immediately to level at 3-3.

A tie-break was needed to separate them after that, with Djokovic's superb forehand winner sealing the first set in style.

Fritz broke Djokovic in the opening game of the second set, but a simple missed backhand from the American helped his opponent break back to make it 5-5.

That set the stage for a high-quality tie-break, which Djokovic ultimately won to claim victory in one hour and 54 minutes.

"I had to fight to survive," Djokovic said on court afterwards. "I didn't feel very reactive today or very comfortable.

"I knew coming into today's match from yesterday's gruelling battle against Medvedev it would take me some time to adjust and find the dynamic movement I need against Fritz, who is one of the best servers on the tour.

"I am very pleased to have overcome this one as I don't think it was one of my best days with my tennis, but I managed to hang in there."

Should Djokovic beat Casper Ruud or Andrey Rublev in Sunday's final, he will claim the largest payday in tennis history, with $4,740,300 up for grabs for sealing the trophy undefeated.

Andrey Rublev produced a stirring fightback to defeat Stefanos Tsitsipas and reach the last four of the ATP Finals for the first time on Friday.

Rublev had failed to make it out of the group stage on each of his first two appearances at the season-ending showpiece.

It initially looked as if he would fall short once again in this winner-take-all clash with Tsitsipas, with both men looking to join Novak Djokovic in progressing from the Red Group.

He was outclassed by Tsitsipas in the first set but showed the grit to recover from 0-30 down in the opening game of the second to find a crucial hold of serve.

That proved the catalyst for a stunning turnaround, as Rublev dominated with his fierce forehand and a series of superb passing shots to seal a 3-6 6-3 6-2 victory in Turin.

He will face Casper Ruud on Saturday for a place in the final.

Rublev told Prime Video of that semi-final encounter: "I'm really looking forward because Casper is such a nice person, great player, great fighter, he has achieved so many things this season, so it's going to be a really good challenge for me."

Novak Djokovic finished with a perfect group-stage record at the ATP Finals after beating Daniil Medvedev 6-3 6-7 (5-7) 7-6 (7-2) in a lengthy three-hour contest on Friday.

Djokovic – who is bidding to equal Roger Federer's record of six ATP Finals titles – sealed his spot in the last four by beating Andrey Rublev on Wednesday, but he was in no mood to do the already-eliminated Medvedev any favours in Turin.

The 21-time grand slam winner dominated the opening set, winning 89 per cent of points behind his first serve and hitting several outstanding cross-court forehand winners.

Djokovic began the second set in similar fashion, but saw his standards dip when he returned to the court following a long stoppage at 5-5.

The rejuvenated Medvedev forced a tie-break with a delightful drop shot before taking advantage of a rare double fault from Djokovic to level the match. 

With the exhausted Djokovic visibly shaking ahead of the decider and his semi-final against Taylor Fritz looming, the Serbian's commitment to Friday's dead rubber could have been called into question, but he found a second wind to take the match away from Medvedev.

Djokovic was on the ropes when he saw his serve broken for the first time in the tournament nine games into the third set, but he hit back immediately and then forced another tie-break. 

The Serbian was back to his exquisite best from there on as he sealed the win by hitting a huge forehand winner down the line, though the drawn-out nature of his victory could yet play into Fritz's hands.

Having qualified for his first ATP Finals, Taylor Fritz is now through to the last-four as he prevailed 7-6 (7-4) 6-7 (5-7) 6-2 against Felix Auger-Aliassime in a match where the winner would advance from the Green Group.

There were no break point opportunities in the first set on the back of elite serving from both players, with Fritz converting 90 per cent (19/21) of his accurate first serves into points. However, after giving up a mini-break to begin the tiebreaker, Fritz steadied and snatched three mini-breaks of his own to take the opener.

It was more of the same in the second set, with Auger-Aliassime taking his turn to dominate with his serve. In a near carbon-copy, the Canadian won exactly 90 per cent (19/21) of the first serves he landed fair, and Fritz had to save the only three breaks points of the frame to force another tiebreaker.

When Auger-Aliassime's serve slipped in the third set, so did any chance of taking the match. He won only 52 per cent of his service points (14/27) in the frame, while Fritz maintained a stellar level at 89 per cent (16/18), securing a double-break and the victory.

Having finished second in his group, Fritz will next take on the winner of the Red Group, which will likely be Novak Djokovic as he is the only undefeated player through two games.

Rafael Nadal wrapped up his ATP Finals campaign with a 7-5 7-5 victory over Casper Ruud on Thursday.

The Spanish great had already failed to make the last four after suffering defeat in his first two matches in Turin, but he finished his year in style courtesy of a hard-fought win over Ruud.

Nadal held firm when two break points down at 4-4, before breaking to love to take the opening set.

He sealed victory in the 12th game of the second set, powering a cross-court backhand winner to move 15-40 ahead and set the stage for a win that saw him end the year with a 39-8 tour-level record.

"I can't ask for more," Nadal said. "2022 has had a tough six months, two Grand Slams, and finishing the year in a high spot in the rankings. So, I can't complain at all. At my age, to be able to achieve and be competitive means a lot for me.

"For 2023, just let's try to have the right preparation, work the proper way and start the season with the right energy, the right attitude, to reach the level that I need to be competitive from the beginning. Let's try it, I am excited about it."

Ruud had already progressed to the semi-finals in Italy for a second consecutive year.

Stefanos Tsitsipas saw off an impressive Daniil Medvedev comeback bid to keep his ATP Finals last four hopes alive with a 6-3 6-7 (11-13) 7-6 (7-1) win in Turin.

With both men having lost their opening match in their first red group encounters, the two headed into their Wednesday match knowing they needed a victory to stay in the semi-final hunt.

Now, it will be 2019 Finals winner Tsitsipas who remains in the mix after seeing off 2020 champion and former US Open winner Medvedev across a two-hour-and-21-minute encounter, handing Novak Djokovic the group in the process.

The Greek second seed looked to be racing away to an early finish after cruising to the first set, but found himself embroiled in a much closer follow-up.

A bruising second set forced the pair into a lengthy tie-break, which stretched its points out to double figures before Medvedev prevailed.

The two could then not be separated in the third, only for Tsitsipas to dominate the tie-break the second time around and race away to a crucial win that sets up a winner-takes-all clash with Andrey Rublev.

Novak Djokovic boosted his hopes of claiming a record-equalling sixth ATP Finals title by clinching a semi-final spot with a 6-4 6-1 win over Andrey Rublev in Turin.

Having overcome Stefanos Tsitsipas in his opening red group match, Djokovic endured spells of pressure from the sixth seed throughout Wednesday's opening set before clinching the all-important break in the 10th game.

The 21-time grand slam winner found the going far easier in the second set, breaking Rublev's serve at the first opportunity before repeating the trick in the sixth game.

Djokovic's backhand was particularly impressive as he dominated proceedings from the baseline, while the Serbian won 94 per cent of points behind his first serve and did not give up a single break point during the match.

The 35-year-old only committed six unforced errors en route to his 68-minute victory, as he joined Casper Ruud in sealing a place in the final four in Turin. 

Djokovic has now won his opening two group matches in four of his last five campaigns at the ATP Finals, and he appears the strong favourite to equal Roger Federer's record of six titles at the competition.

Casper Ruud secured his place in the last four of the ATP Finals and ensured Carlos Alcaraz will be the year-ending world number one by beating Taylor Fritz on Tuesday.

Ruud made it two wins out of two in the Green Group to seal his semi-final spot with a 6-3 4-6 7-6 (8-6) defeat of Fritz in Turin.

The third seed eliminated Rafael Nadal when he won the first set and in doing so guaranteed that injured 19-year-old Alcaraz will be the youngest player to be at the top of the ATP rankings at the end of a year.

Ruud stormed into a 3-0 lead and did not allow Fritz a way back into the first set, but the American broke for the first time to level the match when his opponent was serving to stay in the second.

The battling Fritz fended off two break points in the fifth game of the deciding set and saved two match points as he fought back from 5-1 down in the tie-break to draw level at 6-6.

Norwegian Ruud was not to be denied, though, becoming the first player to reach the semi-finals when eighth seed Fritz drilled a forehand long at the Palbata Alpitour.

Fritz will do battle with Felix Auger-Aliassime on Thursday for a place in the last four.
