Third seed Shelby Rogers eased into the second round of the MUSC Women's Health Open while fifth seed Misaki Doi retired in a three-hour epic on Monday in Charleston.

World number 46 Rogers, who reached the last 16 at last week's Volvo Car Open in Charleston, proved too good for fellow American Caty McNally winning 6-0 6-1 in just over an hour.

Doi's match with countrywoman Nao Hibino lasted much longer, extending to three hours and nine minutes with the latter progressing in a walkover 7-5 5-7 6-6. Doi succumbed to cramps in the third set tiebreaker.

Seventh seed Lauren Davis defeated Coco Vandeweghe 7-6 (7-3) 6-4 in their All American battle while Australian sixth seed Ajla Tomljanovic cruised past Renata Zarazua 6-1 6-1 in the final match of the first day.

Eighth seed Madison Brengle also progressed in three sets past Natalia Vikhlyantseva and unseeded Dane Clara Tauson won 6-3 6-3 over Liudmila Samsonova.

Rain curtailed much of Monday's schedule at the Monte Carlo Masters but it could not prevent Aslan Karatsev from continuing his hugely impressive start to the season.

Karatsev, a surprise Australian Open semi-finalist and a champion in Dubai last month, overcame Lorenzo Musetti, the Italian teenager who was a semi-finalist in Acapulco in March, in straight sets after a four-hour rain delay.

He went into that interruption with a 4-3 lead in the first set and duly polished off the next two games on his return to the court.

The Russian sent down 23 winners as he completed a 6-3 6-4 win in 88 minutes, his last a cross-court backhand that set up a second-round meeting with Stefanos Tsitsipas.

"It was a really tough match [for] my first match of the season on clay [with] tough weather conditions," said Karatsev.

"We started in the morning [and] I started pretty well, I broke him and then the court was getting heavy, the ball was heavy.

"It is tough to play against him. [He is] really fit, [he] runs a lot and gives everything back, so you have to build the point by yourself and close the point by yourself."

There were mixed fortunes for Australians Alex de Minaur and John Millman in Monaco.

De Minaur went down to a surprise straight-sets defeat to Alejandro Davidovich Fokina but Millman broke Ugo Humbert four times in a 6-3 6-3 win.

Next for Millman is either Felix Auger-Aliassime or Cristian Garin, whose first-round contest was among those unable to finish because of the inclement weather on the Cote d'Azur.

Tommy Paul also progressed to the next round, with five matches on court when play was cancelled for the day.

Veronika Kudermetova became the first winner of the Charleston Open since Serena Williams to triumph without dropping a set all week.

The 23-year-old Russian crushed the hopes of Montenegrin rival Danka Kovinic in Sunday's final, landing her maiden WTA Tour title with a 6-4 6-2 victory.

It meant Kudermetova sealed a perfect tournament, winning all six of her matches without being taken to a deciding set, just as superstar and 23-time grand slam champion Williams managed in 2012.

World number 38 Kudermetova said, quoted on the WTA website: "All the matches were really tough. It's really tough matches for nerves, and the tennis part, but I'm really proud of myself that I can take the first title. I'm really happy.

"It means a lot. It shows me that I can play really well, that I can beat good players, and if I play like this and keep working, I think I can be in the top 10 or higher."

The Copa Colsanitas title went to Colombian 19-year-old Maria Camila Osorio Serrano, a former US Open junior champion who entered the tournament on a wildcard but came through the field to also grab a first senior singles title.

She sank the trophy prospects of Slovenian fifth seed Tamara Zidansek, with the world number 180 recording a 5-7 6-3 6-4 victory, describing her success as "unreal".

David Goffin made an encouraging start to the Monte Carlo Masters as he beat Marin Cilic, though Jordan Thompson found things much harder against Benoit Paire.

World number 14 Goffin had lost his previous three matches heading to Monaco, but the Belgian delivered a sharp performance on Sunday, winning 6-4 3-6 6-0.

Open Sud de France champion Goffin did not start well, and had to come from 3-0 down in the first set, but Cilic made 52 unforced errors to help his opponent progress.

"It’s a good win. [This is my] first tournament on clay [in 2021]. Starting with a victory is good," said 2017 Monte Carlo semi-finalist Goffin, quoted on the ATP website.

"I did what I needed to do to win that match. I was playing better and better. In the first and second set, I had problems with the returns. In the third set, I was more consistent. It was a good match."

Goffin will face Marco Cecchinato or Dominik Koepfer in the second round, where he has been joined by Australian Jordan Thompson.

Thompson, the world number 62, needed three hours and two tie-breaks to beat Paire 6-4 6-7 (3-7) 7-6 (7-5), as the Frenchman's dismal string of results in 2021 continued.

Paire has now won just one of 10 matches this calendar year, while Thompson registered a fifth win of the season.

Pablo Carreno Busta won his first home ATP Tour title at the Andalucia Open on Sunday, while Lorenzo Sonego triumphed in Cagliari.

Hunting a fifth Tour title, top-seed Carreno Busta needed three sets to overcome compatriot Jaume Munar 6-1 2-6 6-4 in Marbella.

It is his 200th tour-level win, though it took him two hours and 21 minutes to claim his maiden Spanish title, and his first win since 2019.

Carreno Busta certainly had to work hard for it, with Munar having battled to 4-4 in the decider.

Yet a seventh break point of the ninth game was taken by Carreno Busta, whose powerful backhand return forced his 23-year-old opponent into an error.

Meanwhile, Sonego became the first Italian since Filippo Volandri in October 2006 to win an ATP Tour title on home soil as he overcame Laslo Djere in the Sardegna Open. 

Serbian Djere was on a nine-match winning streak in Italy, but Sonego – who won the doubles title on Saturday – succeeded 2-6 7-6 (7-5) 6-4.

Sonego is the first player since Feliciano Lopez at the 2019 Queen's Club Championships to win both the doubles and singles titles, and the first Italian to do so since Matteo Berrettini at the 2018 Swiss Open Gstaad.

It represents a second tour-level triumph for world number 34 Sonego, who previously won the 2019 Antalya Open.

There will be no dream first WTA Tour final for Paula Badosa at the Charleston Open after she was defeated in the last four by Veronika Kudermetova.

Badosa claimed the biggest win of her career so far in the quarter-finals when she knocked out world number one Ash Barty.

But the 23-year-old, twice beaten in the semis at WTA 250-level events in the past year, came up short against 15th seed Kudermetova.

The Russian was clinical, taking four of her six break point opportunities in a straightforward 6-3 6-3 success.

Kudermetova had previously knocked out Sloane Stephens but will now be favourite against Danka Kovinic.

The underdog's straight-sets defeat of Ons Jabeur in the last four should ensure there is no complacency from Kudermetova.

In Bogota, 19-year-old wildcard Maria Camila Osorio Serrano will play for the title after swatting aside qualifier Harmony Tan 6-1 6-2.

The former top-ranked junior will have to negotiate fifth seed Tamara Zidansek, however, after she defeated Viktoriya Tomova 6-3 7-5.

Top seed Pablo Carreno Busta and fellow Spaniard Jaume Munar will meet in the Andalucia Open final on Sunday. 

Carreno Busta was pushed all the way by Albert Ramos-Vinolas in a pulsating semi-final, ultimately coming through 6-1 3-6 7-6 (7-5). 

"It was so close. I don't know what happened in the second set," Carreno said. "At the beginning of the match, I was very focussed on my game and being aggressive. 

"After that, Albert, of course, started to push [back] more and [I] started to lose my level a little bit. 

"I just kept fighting all the time, and I want to thank everyone [in the crowd] for their support. This is what we missed last year, the crowd. It's very important to play these kinds of very close matches with a crowd like this."

He will take on Munar after the 23-year-old edged past Carlos Alcaraz 7-6 (7-4) 6-4. 

Munar, who reached a final on the ATP Challenger Tour last week, said: "I feel happy and excited. I've been working a lot during the last [few] months. 

"It's a gift for me to be here in a final, and especially in Marbella which is one of my favourite places. I feel excited."

Elsewhere, Lorenzo Sonego is aiming to become the first Italian to win an ATP Tour clay-court title on home soil for 15 years when he takes on Laslo Djere in the final of the Sardegna Open on Sunday. 

Sonego, 25, overcame American Taylor Fritz 6-4 5-7 6-1 to give himself the opportunity to add to his Antalya Open title from 2019. 

Standing in his way is Serbian Djere, who cruised past Nikoloz Basilashvili 6-2 6-0 in just 52 minutes. 

Djere was in control from the outset and from 3-2 in the first set went on to win nine straight games, helping him to his third ATP Tour final.

World number one Ash Barty has been knocked out of the Charleston Open after a straight-sets loss to unseeded Spaniard Paula Badosa in Friday's quarter-finals.

Badosa won 6-4 6-3 over the favoured Australian in one hour, 16 minutes to book a spot in the last four on the green clay and a meeting with 15th seed Veronika Kudermetova.

Kudermetova beat 2017 US Open winner Sloane Stephens 6-3 6-4 in her first win over a grand slam winner.

Former French Open junior champion Badosa, who beat fifth seed Belinda Bencic in the second round, claimed her second career victory over a top-20 player against Barty.

Barty may have hit 34 to 19 winners but she also made twice as many unforced errors, 24 to 12.

The Spaniard broke Barty's serve five times while she sent down seven aces and saved 12 of 14 break points.

"I was quite nervous today but I think I served very well and I think that was the key for the match," Badosa said in her on-court interview.

"It was a tough match but I was there until the last moment and I managed to win."

World number 71 Badosa becomes the lowest-ranked player to beat Barty since September 2019.

The Australian had won eight matches in a row after last week's triumph at the Miami Open.

Unseeded Montenegrin Danka Kovinic came from a set down to topple 11th seed Yulia Putintseva 6-7 (2-7) 7-5 6-1.

Kovinic, who knocked out Petra Kvitova in the third round, will play 12th seed Ons Jabeur in the semi-finals after she overcame Coco Gauff 6-3 6-3.

Meanwhile, at the Copa Colsanitas in Bogota, fifth Tamara Zidansek beat Italy's Sara Errani 6-3 6-4 to claim a spot in the semi-finals.

Viktoriya Tomova outlasted qualifier Nuria Parrizas-Diaz 5-7 6-2 6-4 in almost two and a half hours, while Harmony Tan and local wildcard Maria Camila Osorio Serrano also won.

Top seed Pablo Carreno Busta led a clean sweep for home players to head up an all-Spanish semi-final slate at the Andalucia Open, where teenage sensation Carlos Alcaraz made history.

Carreno Busta demolished seventh seed Soonwoo Kwon 6-4 6-0, while Casper Ruud was stunned in straight sets by wildcard Alcaraz.

The 17-year-old backed up his victory over the veteran Feliciano Lopez in style, becoming the youngest ATP Tour semi-finalist since Alexander Zverev at Hamburg in 2014 with a 6-2 6-4 win.

Albert Ramos-Vinolas will face Carreno Busta after beating Norbert Gombos 6-7 (4-7) 7-5 6-4, while Alcarez is next on the agenda for compatriot Jaume Munar, who was taken the distance by Ilya Ivashka having overcome second seed Fabio Fognini on Thursday.

Taylor Fritz continued his solid form this season with a straight sets victory over Aljaz Bedene to reach the semi-finals of Sardegna Open.

Fritz is playing as the US number one for the first time in Cagliari this week and he made light work of Bedene, prevailing 6-3 6-4 to book a showdown with third seed Lorenzo Sonego, who beat Yannick Hanfmann 3-6 7-6 (8-6) 6-3 despite being 3-5 down in the second.

Seeded second and ranked 30 in the world, Fitz improved his 2021 record to 11-5 and will look to avenge a defeat in his only other meeting with Sonego on clay, when he lost at Roland Garros last year.

Lorenzo Musetti thrilled as he saved four match points to sink top seed Dan Evans on Thursday but bowed out after another epic, losing to Serbia's Laslo Djere 6-4 4-6 6-2 in two hours and 21 minutes.

Djere, who beat sixth seen John Millman en route to the quarter-finals, will face Nikoloz Basilashvili after the battle between seeds four and five ended 7-5 4-6 6-3 in the Georgian's favour.

Jose Mourinho and Gary Lineker led tributes from the football world to Prince Philip, the Duke of Edinburgh, after his death at the age of 99 was announced.

Tottenham boss Mourinho broke off from answering football questions in a pre-match news conference, saying the loss of the husband of Queen Elizabeth II would be felt far beyond British shores.

The Portuguese head coach said: "I’m sorry, I will answer your question. I just read some sad news about Prince Philip. I would like to express my condolences to the Royal Family and to be very honest, and say I have deep, deep, deep, the utmost respect for the Royal Family.

"I believe that it is not just this country that is going to be sharing these feelings, because I'm not English and I know that many like myself will have the utmost respect."

Mourinho, who has spent much of his coaching career in England, added: "I feel sad for the departure of Prince Philip on a personal basis, because I have only positive feelings for the meaning of the family. I feel very sorry. But unfortunately his life ends and we have to keep going."

Former England striker Lineker, now a renowned broadcaster, wrote on Twitter: "Sorry to hear that Prince Philip has passed away. Served this country over many, many decades. Sincerest condolences to Her Majesty, The Queen and The Royal Family. RIP Prince Philip."

The Premier League said it was "deeply saddened" by the news, adding: "As a mark of respect, players will wear black armbands and there will be a minute's silence before kick-off at all Premier League matches played tonight and across the weekend."

The Football Association, which the duke served as president from 1955 to 1957, said it felt "Immense sadness".

The FA asked royal and government authorities whether football should be allowed to continue this weekend and was given the green light.

"Following the sad passing of His Royal Highness The Prince Philip, Duke of Edinburgh, the FA has sought guidance from the Royal Household and Her Majesty's Government," the FA said. "We can confirm all football fixtures this evening and over the weekend (10-11 April) can continue at the discretion of competition organisers.

"The FA will be recommending that black armbands are worn and a minute's silence is observed before matches are played, including tonight's England women's international fixture in France. As a mark of respect, all flags at Wembley Stadium and St George's Park will fly at half-mast and the Wembley arch will also be lit."

Organisers of Saturday's Grand National said the race would go ahead at Aintree, preceded by a two-minute silence on the course, with "jockeys invited to wear black armbands".

Wimbledon, London's tennis grand slam, said it wished to "convey our deepest sympathy to Her Majesty The Queen and The Royal Family".

Imran Khan, the prime minister of Pakistan and former captain of his country's cricket team, wrote on Twitter: "My condolences on the demise of HRH Prince Philip, Duke of Edinburgh. Britain has lost a wise elder who was imbued with a unique spirit of public service. His role in promoting Pakistan-UK relations will always be remembered."

Prince Philip was a two-time former president of the MCC and a noted cricket enthusiast, playing what was described as an "instrumental" role in introducing trophies for winners of the County Championship.

Ian Watmore, chair of the England and Wales Cricket Board, said: "I'm sure I speak for the entire cricket family when I say how sad I am to hear of the passing of the Duke of Edinburgh.

"His passion for the game we all love was well known and the trophies presented to the men's and women's county champions are a tribute to his dedication to our sport. We owe him a great debt for his support and passion over many decades."

Top seed Ashleigh Barty moved into the quarter-finals with a three-set win over Shelby Rogers while Petra Kvitova and Garbine Muguruza exited in the Round of 16 of the Volvo Car Open in Charleston.

World number one Barty was pushed all the way by 52nd ranked Rogers, with both players trading breaks in the final set, before the Australian prevailed 7-6 (7-3) 4-6 6-4.

The victory extends Barty's winning streak to eight matches having won last week's Miami Open.

Barty won 82 per cent of first serve points and sent down 10 aces to get the edge on the American, who saved eight of 13 break points throughout the match.

"The conditions are difficult. It's pretty quick," Barty said in her on-court interview post-game.

"Shelby was able to control the centre of court for a lot of the match. It was about trying to get control when I could. She's an exceptional player, it's always a fight no matter what surface or where we are in the world. It's always one that I enjoy."

Barty will play Spaniard 71st ranked Paula Badosa in the quarter-finals after she beat Caty McNally 6-3 6-3.

Third seed Kvitova was the major casualty on Thursday, losing 6-4 6-1 to Montenegrin Danka Kovinic.

The first set was tightly fought before Kovinic pulled away as Kvitova's errors mounted.

"We both have pretty big serves and she's very good hitting from the baseline," Kovinic said post-game. "Today it was the key that I tried, and did it really well, to take her pace of the ball and use her energy."

Sixth seed Garbine Muguruza also bowed out injured, despite leading 6-0 2-2 against 11th seed Yulia Putintseva.

Muguruza laboured for a few games after a medical time-out before retiring with a left leg injury. Putintseva will next face Kovinic.

Seeds Ons Jabeur, Veronika Kudermetova and Cori Gauff also progressed to the last eight, while Sloane Stephens won in straight sets against Ajla Tomljanovic.

Meanwhile at the Copa Colsanitas second round in Bogota, seventh seed Tereza Martincova was knocked out, going down 6-3 6-3 to Colombian teenager Maria Osorio Serrano.

On the outdoor clay courts, fifth Tamara Zidansek moved into the quarter-finals with a 6-2 6-3 win over Giulia Gatto-Monticone, while Harmony Tan beat Daniela Seguel.

Top seed Dan Evans was knocked out of the Sardegna Open as Lorenzo Musetti saved four match points to progress to the quarter-finals.

NIneteen-year-old Musetti trailed 6-3 in the third-set tie-break after letting an earlier match point slip through his grasp.

But Evans could not convert any of his first three match points and, after Musetti let another one go begging, the Briton failed to take advantage of his fourth opportunity.

Evans' profligacy eventually proved costly, Musetti converting his third match point with a well-executed forehand drop shot to clinch a 6-1 1-6 7-6 (10-8) triumph.

Seven of Musetti's 12 ATP Tour level wins have now come against players in the top 35 of the rankings.

"The secret for me is not to think about [their ranking], to just play them like other opponents," said Musetti, quoted on the ATP website. "I try to play my game… and try to play as good as I can.

"That is what I did. With them, I always play good. I don't know why. I have no pressure and I feel free. I have no pressure to win and today was the same."

Sixth seed John Millman lost in straight sets to Laslo Djere, but third seed Lorenzo Sonego eased past Gilles Simon 6-4 6-1 to set up a meeting with Yannick Hanfmann, who overcame Marco Cecchinato.

At the Andalucia Open, the seeds tumbled out in Thursday's action.

Second seed Fabio Fognini was thrashed 6-2 6-1 by Jaume Munar, Alejandro Davidovich Fokina lost in straight sets to Ilya Ivashka and sixth seed Feliciano Lopez was undone by a comeback from Carlos Alcaraz.

Seventeen-year-old Alcaraz recovered after losing the first set to beat veteran Lopez 4-6 6-2 6-4. Bucking the trend of the day, third seed Casper Ruud prevailed 6-3 6-2 against Gianluca Mager.

The French Open will take place a week later than initially scheduled this year, a move aimed at increasing the possibility of spectators attending the event in Paris.

Action at Roland Garros was due to begin with qualifying on May 17, reverting back to a more traditional time in the tennis calendar after taking place last year in September and October.

That move was made due to the impact of the coronavirus pandemic, taking place after the US Open while Wimbledon was cancelled.

With France currently in a third nationwide lockdown as part of measures to slow the rise in COVID-19 cases, the ATP and WTA Tours released a joint statement on Thursday confirming the main draw at Roland Garros will now begin on May 30 instead.

"Tennis has required an agile approach to the calendar over the past 12 months in order to manage the challenges of the pandemic, and this continues to be the case," the statement read.

"The decision to delay the start of Roland Garros by one week has been made in the context of recently heightened COVID-19 restrictions in France, with the additional time improving the likelihood of enhanced conditions and ability to welcome fans at the event.

"Both the ATP and WTA are working in consultation with all parties impacted by the postponement to optimise the calendar for players, tournaments and fans, in the lead-up to and following Roland Garros.

"Further updates will be communicated in due course."

Rafael Nadal is the defending men's champion, the Spaniard having secured the clay-court title for a 13th time in 2020. However, there was a new winner in the women's tournament, Iga Swiatek of Poland defeating Sofia Kenin in the final.

A statement released from the Grand Slam Board backed the move to postpone the French Open, while also announcing the grass-court season will be reduced by one week as a consequence.

"All four grand slam tournaments are united in their view on the importance of a meaningful build-up to every grand slam, to provide players of all competitive levels with appropriate opportunities to practice, prepare and compete on the relevant surface," a statement released via Wimbledon's official website read.

"It was for this reason that the grand slams, together with the Tours, were supportive of changes to the calendar to create an enhanced grass-court season of three weeks between Roland Garros and the Championships from 2015 onwards. It is widely agreed that this change has been very successfully received.

"However, given the considerable challenges ahead of the FFT in staging Roland Garros, and to avoid further impact on the rest of the calendar, the grass-court season will be reduced by one week in 2021."

Wimbledon will remain as planned, the main draw beginning on June 28 with qualifying taking place the week beforehand.

Ash Barty won her first match on clay since reigning supreme at the 2019 French Open as the world number one rolled into the Volvo Car Open round of 16.

Barty – who last featured in a clay-court match en route to Roland Garros glory almost two years ago amid the coronavirus pandemic – made light work of Misaki Doi 6-2 6-1.

Miami Open champion last week, top seed Barty continued where she left off at the WTA 500 event on Wednesday, closing out proceedings in just over an hour in Charleston.

"I had to use it as an opportunity to try and build some comfort," Barty said. "I think having a couple days between Miami and playing this first match was important, to have my body rest, but to also try and prepare to change surfaces. It was a very quick turnaround, but I felt great out there tonight."

Barty – who now boasts a 15-2 win-loss record in 2021 – will next face Shelby Rogers after she outlasted 13th seed Amanda Anisimova 1-6 7-5 6-4.

As for second seed Sofia Kenin, the 2020 Australian Open champion slumped to a shock 4-6 6-3 6-4 defeat against Lauren Davis midweek.

World number four Kenin – runner-up at last year's French Open – eased to the first set but fellow American Davis, ranked 79th in the world, changed tactics to fine effect.

"I was a bit uncomfortable so I just really dug deep and really started to think about how to beat her and I found that heavy deep balls were not her favourite," the 27-year-old Davis said.

"Being on clay, the ball bounces high, pushing girls back, so it's very effective."

Kenin took a medical timeout at 3-0 down in the deciding set but, despite reeling off the next three games, she was unable to see Davis off as her 2021 woes continue.

Davis now heads into another all-American clash with teenage sensation Coco Gauff – who came from 1-3 down in the third to defeat Liudmila Samsonova 4-6 6-1 6-4 in an absorbing two-hour contest.

Belinda Bencic – the fifth seed – crashed out as Paula Badosa claimed the first top-20 win of her career following a 6-2 6-7 (2-7) 6-1 success.

Badosa will face Caty McNally in the last 16 after the 19-year-old American beat Anastasija Sevastova 7-6 (7-3) 2-6 6-4.

Seventh seed Elise Mertens was another big name to depart as Alize Cornet prevailed 7-5 6-3, although 15th seed Veronika Kudermetova and 12th seed Ons Jabeur progressed in with the minimum of fuss.

Former US Open champion Sloane Stephens, meanwhile, topped eighth seed Madison Keys 6-4 6-4.

Seeds were even more vulnerable at the Copa Colsanitas in Bogata, including the top-seeded Saisai Zheng who was dispatched 6-4 6-1 by Stefanie Voegele.

Zheng's compatriot Yafan Wang, seeded eighth, went down 6-3 6-3 to Viktoriya Tomova.

Arantxa Rus and Jasmine Paolini, the third and sixth seeds respectively, lost in three to Spanish duo Nuria Parrizas Diaz and Lara Arruabarrena.

Pablo Carreno Busta got his quest to win a maiden ATP Tour title in his homeland under way with a straight-sets defeat of Mario Vilella Martinez in the Andalucia Open.

Top seed Carreno Busta needed an hour and 38 minutes to dispatch his fellow Spaniard 7-6 (7-2) 6-3 in Marbella on Wednesday.

Carreno Busta won 73 per cent of points on his first serve and saved the only two break points he faced to set up a quarter-final against Soonwoo Kwon, who beat Facundo Bagnis 6-1 6-3.

Albert Ramos-Vinolas was another home contender to progress, getting the better of Ricardas Berankis 6-3 4-6 6-3, while Norbert Gombos ousted eighth seed Federico Delbonis 5-7 7-6 (7-4) 7-6 (7-1).

There were no surprises in the Sardegna Open, where all three seeds in action moved into the last eight.

Taylor Fritz, the second seed, saw the back of Andrej Martin 6-2 7-6 (7-4) to set up a meeting with Aljaz Bedene, who beat Egor Gerasimov 6-4 7-6 (7-5).

Fifth seed Jan-Lennard Struff needed only 81 minutes to defeat qualifier Liam Broady 6-4 6-2, while Nikoloz Basilashvili rallied from a set – and five match points – down to see off Jozef Kovalik 4-6 6-4 7-5.
