Fabio Fognini is using the ATP Tour's suspension due to the coronavirus pandemic to undergo surgery on both ankles, the world number 11 revealed on Saturday.

The Italian won the Monte-Carlo Masters last season but has been dealing with long-standing ankle issues.

The 2020 campaign has been paused since March amid the COVID-19 crisis, but Fognini saw no improvement in his injury problems when he returned to training recently.

Fognini, who broke into the top 10 of the ATP rankings for the first time in 2019, sought medical advice and was set for arthroscopic surgery in Italy on Saturday.

"I've been having a problem with my left ankle for three and a half years now," he wrote to fans on his Twitter page. "It's an issue I've learnt to cope with.

"Then my right ankle started playing up in the past two years as well.

"I had hoped the various issues would go away during the two-month break from the game because of the lockdown, but when I resumed training, they were still there.

"After medical examination and a long discussion with my time, I decided to have arthroscopic surgery on both ankles. I believe it's the right thing to do while the tour is on this enforced break.

"I will undergo surgery in Italy today. I can't wait to be back playing again! I know you will support me. A big hug to all of you!"

The suspension of the Tour has been extended until at least August, with Wimbledon cancelled and the French Open moved to September.

Fognini reached the last 16 of the Australian Open in January but has otherwise struggled for form in 2020, falling at the first hurdle at the ASB Classic, Rotterdam Open and Dubai Tennis Championships.

Stefanos Tsitsipas fought back impressively to progress at the Rotterdam Open, but fellow seed Fabio Fognini tumbled out of the tournament on Tuesday.

Tsitsipas lost the opening set to Hubert Hurkacz and also slipped 2-0 behind in the second, yet he dropped only two further games as he progressed 6-7 (2-7) 6-3 6-1.

The world number six, who had failed to register a victory in his previous appearances at the tournament, moves on to face Aljaz Bedene, a 6-2 6-4 winner against Benoit Paire.

Andrey Rublev, the seventh seed aiming to win a third title already in 2020, wasted little time in reaching the last 16, dismissing Nikoloz Basilashvili 6-2 6-3 in under an hour. 

Next up for Rublev will be Alexander Bublik, who came through a tense three-set battle against French qualifier Gregoire Barrere.

Fognini, meanwhile, lost in straight sets to Karen Khachanov, the Russian converting four of the seven break-point opportunities that came his way against the fifth-seeded Italian.

Felix Auger-Aliassime lost five straight games in the second set against Jan-Lennard Struff but eventually prevailed in a decider, his 6-3 1-6 6-3 victory booking a clash with 2018 runner-up Grigor Dimitrov. 

In the final match of the day, Filip Krajinovic defeated home wildcard Tallon Griekspoor 6-4 6-1.

Tennys Sandgren will play Roger Federer in the Australian Open quarter-finals after beating Fabio Fognini in a tense affair on Sunday.

The American triumphed in four sets - three of which went to tie-breaks - to knock out the 12th seed and book a meeting with Federer, who dispatched Marton Fucsovics after a nervy start.

There were few signs of the jitters for Novak Djokovic against Diego Schwartzman, while Milos Raonic's relentless serving strength saw him power past 2018 finalist Marin Cilic.

Canadian Raonic said he felt "pretty damn good" after a straight-sets win that included 35 aces, although he admitted he will need even more to beat defending champion Djokovic next.

 

SANDGREN FIGHTS THROUGH FOGNINI FRUSTRATION

Sandgren traded winners and barbs with Fabio Fognini before prevailing 7-6 (7-5) 7-5 6-7 (2-7) 6-4 to seal his second Australian open quarter-final berth.

Tempers frayed across four entertaining sets on Melbourne Arena, with the American becoming upset at his opponent's stalling tactics.

Fognini, the 12th seed, argued with the umpire, took a lengthy bathroom break and asked for a medical timeout to treat blisters all before the third set, leading Sandgren frustrated.

"He gets his own rules because you're afraid to step on his toes," the world number 100 told the umpire after taking the opener.

Sandgren, who lost to Chung Hyeon in the last eight two years ago, regained his composure and went on to complete the upset in three hours and 27 minutes.

FEDERER FINDS FORM AFTER EARLY WOBBLE

Federer seemed to be feeling the effects of his epic five-set victory over John Millman as Fucsovics took an early lead on Rod Laver Arena.

However, the 38-year-old recovered in supreme style and seemed somewhere close to his best tennis at the end of a 4-6 6-1 6-2 6-2 victory.

As the full repertoire of shots from Federer began to paint the lines, Fucsovics had little response.

The 20-time major champion is now looking forward to a first meeting with Sandgren. "I have played a lot of tennis in my life, but never against Tennys," he said.

DJOKOVIC POWERS PAST SCHWARTZMAN

Djokovic produced another dominant display to dismantle Schwartzman 6-3 6-4 6-4 on Rod Laver Arena, where the world number two kept his title hopes alive.

While Schwartzman fought hard, it was another routine outing for Djokovic - who reached his 11th Australian Open quarter-final.

Djokovic was broken for the first time since the opening round but was never really in danger, hitting 38 winners and 31 unforced errors.

"Today was a good test because Diego was in form, he hasn't dropped a set in three rounds," the Serbian said afterwards.

"Obviously he can be a very dangerous opponent from the baseline if you give him time. I knew that. I stepped out on the court with a clear game plan what I need to do."

RAONIC TAKES DOWN CILIC

It rained aces as 32nd seed and former world number three Raonic beat former runner-up Cilic 6-4 6-3 7-5.

Raonic progressed to his fifth quarter-final in Melbourne after firing down 35 aces and winning all of his service games in two hours and 19 minutes.

His reward? A showdown with Serbian superstar Djokovic, who boasts a dominant 9-0 head-to-head record.

"I'm going to have to serve well clearly, and then I think I'm going to have to get my return at a high percentage, make him play a lot of those points, and then try to be efficient on my service games," Raonic said in his news conference.

"I think we play quite opposite from each other, and he's done a good job in the past neutralising my serve. So I have really got to focus on my things well and be the one dictating."

Stefanos Tsitsipas suffered a surprise Australian Open exit at the hands of Milos Raonic in the third round on Friday.

The Greek was beaten in straight sets and managed not a single break point against the relentless power and precision of the Raonic serve.

Roger Federer ensured his 100th match win at Melbourne Park was among his most memorable as he survived a gruelling five-set encounter with John Millman.

The six-time champion remains on course for a semi-final against Novak Djokovic, who was ruthless in seeing off the challenge of Yoshihito Nishioka.

Roberto Bautista Agut was edged out by Marin Cilic, and there were also wins for Diego Schwartzman, Marton Fucsovics, Tennys Sandgren and Fabio Fognini.

 

RAONIC LEAVES TSITSIPAS REELING AS DJOKOVIC MARCHES ON

There was a shock for sixth seed Tsitsipas, who simply had no answer to the serve and forehand of Raonic in a 7-5 6-4 7-6 (7-2) defeat.

The 21-year-old struggled to make any inroads against the Raonic attack and was unable to muster even a solitary chance of a break against a player yet to drop serve in this year's tournament.

"It's one shot that you can get knocked down all the time, and you're just there, getting punched in the face with one shot. You can't do much," Tsitsipas said of facing the Canadian.

"I'm not saying it's luck. It's a skill. I felt a bit stupid returning his serves."

Defending champion Djokovic was in imperious form, dispatching Nishioka 6-3 6-2 6-2 to keep his quest for an eighth title on track.

Djokovic described the victory as "one of the best serving matches I've had lately" and credited coach Goran Ivanisevic after firing in 17 aces and dropping just eight points on serve to reach the second week in Melbourne for the 12th time.

The Serbian now faces Schwartzman, who saw off Dusan Lajovic 6-2 6-3 7-6 (9-7).

TON UP FOR FEDERER AFTER TIE-BREAK TURNAROUND

Federer's 100th win at the Australian Open was secured at 0048 local time after a marathon encounter with Millman.

The 38-year-old triumphed 4-6 7-6 (7-2) 6-4 4-6 7-6 (10-8) after four hours and three minutes of brutal tennis against the Australian, who beat him at the US Open two years ago.

Federer fought back from a set down to lead but, after Millman forced a decider, momentum seemed to have swung his way in front of a crowd for once not overwhelmingly backing the Swiss great.

Millman led 3-0 and 8-4 in the final-set tie-break, but Federer rallied from the brink to earn the first match point and promptly took advantage when a Millman volley offered him a routine passing shot.

"Oh God, it was tough," Federer told Jim Courier on court after the match. "Thank God it was a match tie-break, otherwise I would have lost this one."

Federer will face Fucsovics in round four, the Hungarian having beaten Tommy Paul 6-1 6-1 6-4 in a one-sided match-up.

CILIC OUTLASTS BAUTISTA AGUT AS SANDGREN QUELLS QUERRY

Cilic, the beaten finalist in 2018, claimed a memorable 6-7 (3-7) 6-4 6-0 5-7 6-3 victory over ninth seed Bautista Agut to set up a fourth-round showdown with fellow serving heavyweight Raonic.

An all-American clash went the way of Sandgren, meanwhile, as he beat Sam Querrey 6-4 6-4 6-4.

Sandgren meets Fognini in round four, the Italian making relatively light work of Guido Pella in a 7-6 (7-0) 6-2 6-3 victory.

Roger Federer and Novak Djokovic were untroubled, but Grigor Dimitrov was among five seeds to fall at the Australian Open on Wednesday.

Federer produced an excellent performance in a straight-sets thrashing of Filip Krajinovic on Rod Laver Arena.

The Swiss great had received good news before even going on court after three seeds fell in his quarter of the draw, with Fabio Fognini only narrowly avoiding that fate.

Earlier, Djokovic dropped just seven games on his way to a thrashing of Tatsuma Ito in Melbourne.

 

FEDERER, DJOKOVIC EASE THROUGH

Having lost a set in the opening-round victory over Jan-Lennard Struff, Djokovic suffered no such setback against Ito, winning 6-1 6-4 6-2.

A record seven-time champion in Melbourne and 16-time grand slam winner, Djokovic brushed past Ito on the back of 31 winners.

Federer was even more impressive later in the day, crushing Djokovic's Serbian compatriot Krajinovic 6-1 6-4 6-1.

The 20-time grand slam champion looked in fabulous form with 42 winners and just 14 unforced errors, reaching the third round in Melbourne for the 21st straight year.

Federer will next face John Millman, who upset 31st seed Hubert Hurkacz 6-4 7-5 6-3. The Australian stunned Federer at the US Open in 2018.

 

DIMITROV AMONG SEEDS TO CRASH OUT

Dimitrov, a semi-finalist in 2017, bowed out in a surprise 6-4 7-6 (8-6) 3-6 6-7 (3-7) 7-6 (10-3) loss to Tommy Paul.

The Bulgarian 18th seed went up by a break twice in the final set, but lost seven consecutive points from 3-3 in the match tie-break.

Matteo Berrettini, the eighth seed who reached the US Open semi-finals, was edged out by Tennys Sandgren 7-6 (9-7) 6-4 4-6 2-6 7-5.

Sandgren reached the quarter-finals in 2018 and will face Sam Querrey in an all-American third-round clash.

British 30th seed Dan Evans also made a second-round exit, losing to Djokovic's next opponent, Yoshihito Nishioka, 6-4 6-3 6-4.

 

CILIC, RAONIC ADVANCE AS TSITSIPAS GETS FREE PASS

Marin Cilic, runner-up in 2018, eliminated 21st seed Benoit Paire in a thriller.

The Croatian needed three hours, 33 minutes to overcome Paire 6-2 6-7 (6-8) 3-6 6-1 7-6 (10-3).

Next up for Cilic is a man he has lost to twice at the Australian Open in Roberto Bautista Agut, the Spanish ninth seed too good for Michael Mmoh 5-7 6-2 6-4 6-1.

Milos Raonic has reached at least the Australian Open quarter-finals four times and the Canadian has shown impressive form early on this year.

The 29-year-old served 19 aces in a 6-3 6-4 6-2 victory over Cristian Garin on Wednesday and next faces 2019 semi-finalist Stefanos Tsitsipas.

Tsitsipas advanced without hitting a ball after Philipp Kohlschreiber withdrew due to a muscle strain.

 

FOGNINI TAKEN THE DISTANCE BY THOMPSON

It is proving to be an arduous campaign for Fognini, who surrendered a two-set lead before holding his nerve in a decisive tie-break with home hope Jordan Thompson.

The Italian was taken the distance in his first-round meeting with Reilly Opelka after losing the first two sets, and this time it was the 12th seed who almost choked on a healthy lead.

Fognini hurt himself when punching his racket in frustration and was called for a foot-fault in the fifth-set breaker, but he got the job done in a memorable 7-6 (7-4) 6-1 3-6 4-6 7-6 (10-4) triumph that took more than four hours to complete. 

Novak Djokovic vowed to "enjoy every moment" after reaching the second round of the Australian Open on an opening day that saw seeds Denis Shapovalov and Borna Coric crash out.

Djokovic started the defence of his title with a battling 7-6 (7-5) 6-2 2-6 6-1 victory over Jan-Lennard Struff at Melbourne Park on Monday.

Losing his serve three times while dropping the third set and having to edge a close tie-break in the opener meant Djokovic spent longer than he would have hoped on court, but he relished the two-hour-and-16-minute encounter.

Asked about winning his 900th Tour-level match, the second seed said: "I'm obviously very proud of all the achievements, but at the same time I try to remind myself how grateful I am to be playing this sport at a high level at this stage of my career. 

"I can't take things for granted, I'm trying to enjoy every moment. It's a New Year resolution, to enjoy more. It's easier said than done when you're on the court.

"Especially in my position, I'm expected to win all my matches, there's a lot of pressure and emotions involved. But I try to really enjoy it, the two and half hours spent on court were a lot of fun."


SHAPOVALOV AND CORIC FALL AT FIRST HURDLE

The biggest shock of the day saw number 13 seed Shapovalov fall to a four-set defeat against Hungarian world number 67 Marton Fucsovics.

Fucsovics won 7-3 6-7 (7-9) 6-1 7-6 (7-3) in three hours and 13 minutes as the highly-rated Canadian crashed out.

Shapovalov lost his temper with the umpire when he was giving a code violation for racket abuse despite it not being damaged.

"I think that's a terrible call from the [umpire]," Shapovalov said. "The rule [according to] what I know is that if I break my racket, yeah you can code me, but you can't code me for slamming it.

"I'm not doing anything and it didn't impact anyone and the racket was still intact. He gave me a warning because I did it two or three times and I think that's not the way it works."

Number 25 seed Coric was eliminated in straight sets by Sam Querrey. 

The American won 6-3 6-4 6-4 as a dreadful run for Coric, which has seen him win only one of his last 10 matches, went on.
 

FEDERER AND TSITSIPAS COAST THROUGH

Roger Federer progressed in comfortable fashion, the third seed seeing off Steve Johnson 6-3 6-2 6-2 in only 81 minutes.

Johnson only forced one break-point opportunity in the match against the 20-time grand slam and did not convert it.

Sixth seed Stefanos Tsitsipas, the ATP Finals champion and a semi-finalist in Melbourne last year, got off to a smooth start, defeating Salvatore Caruso 6-0 6-2 6-3.

 

RAIN LEAVES MATCHES UNFINISHED

Inclement weather left a host of Monday's other first-round matches incomplete, with Reilly Opelka closing in on an upset against Fabio Fognini when play was suspended at 6-3 7-6 (7-3) 1-0.

Rising star Jannik Sinner has a 2-0 lead over Max Purcell with the third set level at 4-4, while Roberto Bautista Agut was a set up against Feliciano Lopez.

Milos Raonic is one game away from a first-round win, his match against Lorenzo Giustino all-but over with the Canadian 6-2 6-1 5-2 to the good.

Fabio Fognini and Karen Khachanov, the first and third seeds, crashed out of the Auckland Open in their opening matches on Wednesday.

World number 12 Fognini was facing Feliciano Lopez, the oldest player in the draw at 38 who had already won a match earlier in the day as the tournament schedule caught up following weather delays.

Lopez beat Pablo Andujar in three close sets before coming from behind to prevail against Italian Fognini, winning 3-6 6-4 6-3 in just under two hours.

"The first match was tough for me, but I think it was very helpful because it was my first singles match of the season," said Lopez after his day of double duty.

"Without that match, I don't think I would have played the way I did against Fabio."

Australian John Millman recovered from a set down to oust Russian Khachanov 4-6 6-3 6-3.

Denis Shapovalov is the highest seed left in the draw, having defeated fellow Canadian Vasek Pospisil 6-4 7-6 (7-2).

Defending champion Tennys Sandgren is out after another former winner of the event, John Isner, triumphed 7-6 (7-3) 6-7 (1-7) 6-3 in an all-American round-of-16 encounter.

Seeds Benoit Paire and Hubert Hurkacz made it to the quarter-finals, as did Kyle Edmund and Ugo Humbert, who will now play Shapovalov.

At the Adelaide International, Felix Auger-Aliassime won his first match against wildcard James Duckworth, a 6-3 7-6 (7-0) win sending the second seed into the last eight.

Auger-Aliassime said: "Now I'm at a point where I was top 20 in the world. I reached three finals. Now every tournament I play, I play to win. I come, I want to reach the final. I want to give myself a chance to win titles."

Qatar Open champion Andrey Rublev continued his momentum with a 6-3 6-3 win over Sam Querrey and fourth seed Pablo Carreno Busta also progressed in straight sets.

There was a shock, though, as seventh seed Jan-Lennard Struff was beaten 6-3 6-4 by wildcard Alex Bolt.

Albert Ramos-Vinolas joined Bolt in the quarter-finals, as did qualifiers Lloyd Harris and Tommy Paul.

An emotional Nick Kyrgios explained his motivations for donating to the effort fighting Australia's bushfires after helping his nation to victory over Germany at the ATP Cup.

Kyrgios beat Jan-Lennard Struff 6-4 7-6 (7-4) in Brisbane, sending down 20 aces after his pledge to give 200 Australian dollars to the bushfires effort for each service winner he hits in January.

Alex de Minaur – Kyrgios' team-mate at the event, who impressively came from a set down to defeat an ill-tempered Alex Zverev 4-6 7-6 (7-3) 6-2 – followed suit after Kyrgios tweeted his intention to help, while stars from other sports have also joined in.

Brisbane Heat captain Chris Lynn struck three sixes as he top-scored in his team's win over Hobart Hurricanes in the Big Bash League on Friday, with each maximum worth $250 to the recovery effort.

"I don't really care about the praise too much. I just think we've got the ability and platform to do something like that," Kyrgios told Amazon Prime when asked about the movement he inadvertently started.

"My home town is Canberra and we've got the most toxic air in the world at the moment, so it is pretty sad. It's tough."

Having appeared choked up at that point, Kyrgios added: "I just chucked up a tweet and everyone got behind it. It is bigger than tennis.

"It's going to all the families, firefighters, animals, everyone who is losing homes, losing families. It's a real thing.

Australia completed a 3-0 Group F win after Chris Guccione and John Peers beat German doubles pair Kevin Krawietz and Andreas Mies 6-3 6-4.

In the section's other match, Canada were similarly emphatic against Greece, with Denis Shapovalov winning a pair of tie-breaks to best Stefanos Tsitsipas after Felix Auger-Aliassime demolished Michail Pervolarakis 6-1 6-3.

Auger-Aliassime and Shapovalov then combined to win the doubles rubber against the same opponents, prevailing 6-2 6-3.

Great Britain and the United States both allowed leads to slip against Bulgaria and Norway respectively.

In Group C, Cameron Norrie beat world number 423 Dimitar Kuzmanov in three sets and Dan Evans made a fast start against Grigor Dimitrov to go a set up.

But Dimitrov prevailed 2-6 6-4 6-1 and he and Alexandar Lazarov triumphed after three tie-breaks against Jamie Murray and Joe Salisbury in the small hours of the Sydney morning.

Taylor Fritz beat Viktor Durasovic 6-2 6-2 and John Isner had the USA in charge of the second singles rubber when he took the opening tie break versus Casper Ruud, only for two match points and a second breaker to go against him. He eventually lost, going down 7-5 in the deciding set.

Ruud and Durasovic then recovered from dropping the first set to beat Austin Krajicek and Rajeev Ram 10-5 in a match tie-break in Perth.

Steve Darcis and David Goffin inspired Belgium to a 3-0 Group C win over Moldova, while Daniil Medvedev's 1-6 6-1-6-3 victory against Fabio Fognini helped clinch a 3-0 victory for Russia against Italy in Group D.

Croatia's hopes of defending their Davis Cup title took a huge early blow as they were beaten 3-0 by Russia in Madrid on Monday.

Champions a year ago, Croatia's chances of even progressing from the first stage in the 2019 Finals already look remote – with Rafael Nadal's Spain still to play in Group B.

Croatia took on Russia on centre court following the opening ceremony in a match-up that was hindered by key withdrawals ahead of the tournament.

Marin Cilic, who led Croatia to victory in 2018, missed out with injury, while Russia's Daniil Medvedev ducked out citing fatigue.

Russia dealt with the absence of their number one in far more convincing fashion than Croatia, though, with Borna Gojo comfortably eased out 6-3 6-3 by Andrey Rublev in the first of three contests.

The two remaining star names did battle next, but Russia again came out on top as Karen Khachanov rallied past Borna Coric 6-7 (4-7) 6-4 6-4.

And then Rublev and Khachanov teamed up for a straight-sets doubles success against Ivan Dodig and Nikola Mektic.

Elsewhere, there was an upset as Italy went down to Canada 2-1, with both Fabio Fognini and Matteo Berrettini beaten in singles play.

Vasek Pospisil, ranked 150th in the world, defeated Khachanov at the US Open and claimed another scalp against Fognini, before Berrettini was turned over by Denis Shapovalov.

Italy sent in their two stars for the doubles, where they gained a measure of revenge over Pospisil and Shapovalov, winning in three.

Belgium survived David Goffin's awful start to his rubber to win 2-1 against Colombia.

Steve Darcis had earlier seen off Santiago Giraldo in straight sets, but Goffin fell four games behind in the opener against Daniel Elahi Galan before staging a fightback.

He won 3-6 6-3 6-3, although Colombia got on the board with a doubles comeback from Juan-Sebastian Cabal and Robert Farah.

Stan Wawrinka has been forced to pull out of a dream home quarter-final against Roger Federer at the Swiss Indoors Basel due to a back injury.

The seventh seed Wawrinka displayed plenty of grit to dispatch of Frances Tiafoe 6-3 3-6 7-5 on Thursday and was set to meet Swiss great Federer in the last eight.

However, Wawrinka – a losing finalist to Andy Murray at last week's European Open – will not be able to take to the court to face Federer for a 27th time.

"The bad news is that I will have to retire," he said.

"I had some trouble with my back in the last game. I'm sure I cannot make it for tomorrow [Friday]. I will pull out."

Third seed Stefanos Tsitsipas had to fight back to avoid an upset against Ricardas Berankis, the Greek recovering to seal a 6-7 (4-7) 6-2 6-4 triumph. 

Filip Krajinovic is up next after he upset fifth seed Fabio Fognini 6-2 6-4, while Roberto Bautista Agut needed three sets to defeat Richard Gasquet.

Reilly Opelka will take on the Spanish fourth seed after he recovered from a set down to defeat David Goffin 6-7 (4-7) 7-6 (7-4) 7-5.

 

Andy Murray moved into the quarter-finals by beating Pablo Cuevas after the top three seeds crashed out of the European Open, while Fabio Fognini was dumped out in Stockholm on Thursday.

Murray produced another encouraging performance in Antwerp, reaching the last eight of a singles tournament for the second time since returning to the ATP Tour following a hip resurfacing operation in January.

The former world number one saw off eighth seed Cuevas 6-4 6-3 after saving all four break points he faced, winning 82 per cent of points on his first serve and 74 per cent behind his second.

Murrray started strongly and dominated from the back of the court, finishing Cuevas off with back-to-back aces to ensure he will take on Marius Copil.

Copil ousted Diego Schwartzman 6-4 5-7 7-6 (9-7), while top seed Gael Monfils went down 6-3 6-2 to 18-year-old Italian outsider Jannik Sinner and David Goffin, the second seed, was thumped 6-3 6-1 by Ugo Humbert in his homeland.

Jan-Lennard Struff was another seed to fall in the second round, losing 6-3 6-4 to Frances Tiafoe.

Janko Tipsarevic's retirement will have to wait until another day after he hammered ATP Finals contender Fognini 6-1 6-1 to move into the quarter-finals of the Stockholm Open.

Tipsarevic lost just four points on his first serve and will take on lucky loser Yuichi Sugita, who beat Stefano Travaglia in straight sets.

Fourth seed Denis Shapovalov got the better of Alexei Popyrin 6-4 7-6 (7-3) in the Swedish capital, with Pablo Carreno Busta and Cedrik-Marcel Stebe also victorious.

Marin Cilic beat fellow Croatian Ivo Karlovic 6-1 7-6 (7-5) to book a Kremlin Cup quarter-final showdown with Jeremy Chardy, who came out on top against Miomir Kecmanovic.

Andrey Rublev and lucky loser Nikola Milojevic came through their second-round matches versus Egor Gerasimov and Alen Avidzba respectively in Moscow.
