Novak Djokovic is into the last eight at the Paris Olympics after he cruised past Dominik Koepfer in straight sets.

Djokovic triumphed 7-5 6-3 in one hour and 37 minutes at Roland-Garros on Wednesday.

The world number two is in the hunt for a second Olympic medal, having previously claimed bronze in 2008.

Stefanos Tsitsipas, who beat Sebastian Baez, is next up for Djokovic.

The 37-year-old, now into his fourth Olympic quarter-final, has defeated the Greek in each of their last 10 meetings.

"It’s very humid," said Djokovic after his win, with Paris experiencing sweltering conditions.

"I just hope it rains so it cools down the temperature and the air a bit. But you have to accept and embrace the conditions. It's the same for you and your opponent, so you have to make the best out of it."

Lorenzo Musetti, meanwhile, defeated Taylor Fritz, though the latter's compatriot Tommy Paul did beat home hope Corentin Moutet.

Data Debrief: Golden oldie

At the age of 37 years and 61 days, Djokovic is the oldest player to reach the men's Singles quarter-finals at the Olympics since tennis returned to the program in 1988.

Italian Musetti has equalled the best run by a man from his nation in the Olympics singles since 1988 (Paolo Cane in Seoul 1988 and Renzo Furlan in Atlanta 1996).

Daniil Medvedev staved off a Dominik Koepfer fightback to record a battling victory in the French Open first round on Monday.

The world number five raced out the blocks on Court Simonne-Mathieu and eventually triumphed 6-3 6-4 5-7 6-3 in Paris.

Medvedev, a five-time major runner-up and 2021 US Open champion, broke Koepfer's first service game in the French capital with that a seeming sign of things to come.

Though the 28-year-old dropped his serve in the first set, Medvedev had little trouble in responding with the score finely poised at 3-2 to claim first blood at Roland-Garros.

The fifth seed has only ever gone as far as the quarter-finals, three years ago, at the French Open but showed his clinical best to snatch the second set after holding all six service games for a narrow triumph.

World number 65 Koepfer battled back in the third but the resilient Medvedev responded by breaking his German opponent early in the fourth set, finally securing victory in just over three hours.

Data Debrief: Medvedev gets better of Koepfer again

Medvedev has won all four of his meetings with Koepfer, with his most recent such victory seeing him reach the second round at Roland-Garros for the third time in eight attempts.

Since the start of the 2021 season, Medvedev is 27-1 against players ranked outside the top 50 at major events, with his only loss in that run coming against Seyboth Wild in the French Open first round last year.

Koepfer, meanwhile, extends to 1-17 against top-10 players in his career, earning his only such victory against over Gael Monfils – then ranked ninth in the world – at the 2020 ATP Masters 1000 event in Rome.

Daniil Medvedev had to dig deep to overcome Hamad Medjedovic at the Italian Open on Monday and stay in with a chance of retaining his title.

Medvedev came out on top with a 7-6 (7-5), 2-6, 7-5 victory, but was made to work hard to avoid a third-round upset.

After enduring an up-and-down opening two sets in which he hit 10 double faults, Medvedev rallied into a lead before holding off Medjedovic’s fight-back.

The second seed remained composed to break in the match’s final game to advance after two hours and 50 minutes.

Medvedev will now play Tommy Paul in the next round on Tuesday, with the American seeing off Dominik Koepfer 6-4, 6-3.

Data Debrief: Reigning champion fights on

Medvedev has reached the last 16 at all 5 Masters 1000 events this season, with only Alexander Zverev able to match that distinction.

It was not an easy ride for him though, as Medjedovic wanted to prove a point against his first Top 10 opponent in what was his first Masters 1000 third round.

Third seed Alexander Zverev has been knocked out of the Indian Wells Masters by Tommy Paul in his first game since his expulsion from last month's Mexican Open for unsportsmanlike conduct.

Unseeded American Paul triumphed over the German 6-2 4-6 7-6 (7-2) in two hours and 17 minutes, rallying back from a break down in the final set.

Paul hit less winners, 26-21 to Zverev but made less unforced errors 25-19, while his serve and volley game was a key feature.

"I played a really high level today," Paul said during his on-court post-game interview. "The last time I played him, I played well, I put pressure on him so I knew how i wanted to play so I came out and executed him well.

"I played well when it came down to the breaker, so I'm pretty happy with my performance."

Zverev had not played since being expelled in Acapulco after a stunning outburst where he struck his racquet on the umpire chair several times after a doubles defeat.

Ninth seed Felix Auger-Aliassime was a major casualty, going down to Dutchman Botic van de Zandschulp 7-6 (7-4) 6-7 (4-7) 6-3 in three hours and 15 minutes.

The Canadian had 36-27 winners but was let down by 43-26 unforced errors, along with converting only two of his 10 break points.

Van de Zandschulp had failed to take three match points in the second set but showed composure to finish the job in the third.

Wild card Andy Murray was also eliminated in the second round, blowing three set points in the first set before going down to 31st seed Alexander Bublik 7-6 (11-9) 6-3 in two hours and one minute.

Last year's Wimbledon runner-up and Italian sixth seed Matteo Berrettini needed more than two hours to get past world number 86 Holger Rune 6-3 4-6 6-4.

Seventh seed Andrey Rublev defeated Dominik Koepfer 7-5 6-4 to extend his win streak to 10 matches, while 11th seed Hubert Hurkacz beat Oscar Otte 6-3 3-6 6-3.

Other seeds to be eliminated were 22nd seed Aslan Karatsev who went down 7-6 (7-5) 6-4 to American Steve Johnson, while 24th seed Marin Cilic lost 6-7 (7-9) 6-3 7-6 (8-6) to Miomir Kecmanovic.

Roger Federer returned a compliment to Andy Murray and looked ahead to a potential grass-court meeting the morning after a gruelling third-round win at Roland Garros.

Federer made round four at the French Open but was so drained by the experience that he suggested he could yet withdraw from the tournament as he looks to build up fitness ahead of Wimbledon.

The Swiss superstar entered the clay-court major with a 1-2 record for the year, most recently losing to Pablo Andujar in Geneva last month.

However, Federer has strung together three straight wins in Paris, beating Dominik Koepfer in the last 32 in a match that finished in the early hours of Sunday in the French capital.

The match started at 21:00 local time (20:00 GMT), in line with a coronavirus-enforced curfew that ensured the stands were empty on Court Philippe-Chatrier.

Despite the strange experience and a determined opponent, Federer came through in four sets after three tie-breaks to continue his pursuit of a record-breaking 21st grand slam title.

During the match, which finished at close to 01:00 local time (00:00 GMT), fellow great Murray posted on Twitter: "I'm not bothered by the outcome of this match at all.

"Just seeing Federer at 39 off the back of two knee surgeries playing to an empty stadium at 12:30am getting fired up is inspirational to me. Do what you [love]."

Murray himself has overcome a series of major injuries to remain on the ATP Tour, even backtracking on a retirement pledge in 2019.

So, Federer replied on Sunday: "Thank you Sir Andy, the feeling is mutual. You gotta love it. See you on the [grass]."

There was no further comment on potentially quitting the French Open, where Federer is appearing for only the second time since the start of 2016 – he made the semi-finals two years ago.

His sublime major form has slowed over the past decade, making only nine finals compared to 22 in the previous 10 years.

If Federer is able to continue, he faces a tough ask on Monday, taking on Matteo Berrettini, who has become the first Italian to reach the last 16 of all four slams in the Open Era.

Roger Federer says he may withdraw from the French Open as he assesses the physical impact of his epic third round win over Dominik Koepfer on Saturday.

The 39-year-old Swiss prevailed 7-6 (7-5) 6-7 (3-7) 7-6 (7-4) 7-5 over Koepfer in the longest match he has played in 18 months, following double knee surgery, lasting three hours and 35 minutes.

Federer laboured at times in the contest, making 63 unforced errors, fighting hard to triumph in front of an empty crowd locked out by Paris' 9pm curfew, with the match finishing close to 1am.

The 20-time Grand Slam winner has played few tournaments over the past 18 months and conceded the physical toll the match took would make him assess his continuation at Roland Garros.

"We go through these matches, we analyse them highly and look on what's next and will do the same tonight and tomorrow, because I need to decide if I keep on playing or not or is it not too much risk at this moment to keep on pushing, or is this just a perfect way to just take a rest," Federer said at his post-match news conference.

"Because I don't have the week in between here and Halle like normal to see what's best now, if you count back from Wimbledon and so forth.

"It's just a lot going on, but having a match like this, knowing I could have probably played a fifth set but not knowing how I will wake up tomorrow is interesting, to say the least."

He added: "Every match here or Geneva, I have to reassess the situation after the match and see in the morning how I wake up and how the knee feels.

"From that stand point for me, it always goes like that… maybe even more so after a match like this that has been long. Like I explained before, I've not been two-three-and-a-half hour battles in practice either."

Federer's third round win sees him move into the last-16 where he is scheduled to play ninth seed Matteo Berrettini on Monday.

Vasek Pospisil launched a stunning tirade during his three-set defeat to American qualifier Mackenzie McDonald in the first round of the Miami Open on Wednesday.

The Canadian former world number 25 was docked a point for verbal abuse, subsequently conceding the first set, before a meltdown during the change of ends.

Pospisil used a profanity in reference to ATP chairman Andrea Gaudenzi when speaking to chair umpire Arnaud Gabas.

“[Gaudenzi was] screaming at me in a player meeting for trying to unite the players — for an hour and a half," Pospisil said to Gabas. "If you want to default me, I’ll gladly sue this whole organisation.”

He did fight back to win the second set but ultimately lost to McDonald 6-3 4-6 6-3.

Pospisil, who is nowadays ranked 67th, was joined among the first-round exits by last week's Mexican Open semi-finalist Dominik Koepfer, who went down 6-1 6-4 to wildcard Hugo Gaston as he claimed his first career Masters 1000 win.

Sam Querrey, ranked 63rd, also bowed out 6-3 6-4 to Lu Yen-hsun, who will meet world number two Daniil Medvedev in the second round.

YOUNGSTER BEATS VETERAN

Australian youngster Alexei Popyrin secured his maiden win at the Miami Open, knocking out the oldest player in the draw Feliciano Lopez 6-4 7-6 (7-4).

Popyrin, 21, claimed his first ATP Tour title last month in Singapore and backed that up with a strong display against the 39-year-old former top 20 Spaniard.

Recent Open 13 Marseille runner-up Pierre-Hugues Herbert got past Portugal's Pedro Sousa 6-1 6-3, while South Africa's Lloyd Harris defeated Emilio Nava 6-4 7-6 (9-7).

Frances Tiafoe won in the final match of Wednesday, coming from behind to beat Stefano Travaglia 5-7 6-4 6-2.

COMEBACK CAM

Brit Cameron Norrie produced a heroic final-set fightback to claim his spot in the second round, where he will face Grigor Dimitrov.

Norrie trailed 5-1 in the third set against Yoshihito Nishioka, before winning 6-1 3-6 7-5, winning the last six games to clinch victory.

The 56th-ranked Brit sent down eight aces in the victory, although he got the edge on return and converted seven of his 10 break points.

SECOND ROUND

Top seed Medvedev will face Lu on Thursday, while third seed Alexander Zverev will take on Finland's Emil Ruusuvuori.

Norrie will meet Dimitrov, while 11th seed Felix Auger-Aliassime faces Herbert and eighth seed David Goffin will take on James Duckworth.

Harris has a match-up against seventh seed Roberto Bautista Agut.

An earthquake hit Acapulco during Alexander Zverev's clash against Dominik Koepfer at the Mexican Open on Friday.

The broadcast camera shook mid-point during the all-German semi-final encounter.

A 5.7 magnitude earthquake was registered to the north of Marquelia, which is to the east of Acapulco.

Zverev went on to secure a 6-4 7-6 (7-5) victory over Koepfer to reach the final.

Top seed Stefanos Tsitsipas was made to sweat but got past Felix Auger-Aliassime in three sets to reach the Mexican Open semi-finals on Thursday.

World number five Tsitsipas, who was a semi-finalist at last month's Australian Open, defeated seventh seed Auger-Aliassime 7-5 4-6 6-3 in Acapulco.

In a tight contest, back-to-back double faults from Canadian sensation Auger-Aliassime in the eighth game of the third set proved costly as Tsitsipas broke after the pair had held serve throughout the last.

"It got really tight," Tsitsipas said in his post-game interview. "I got a bit lucky with the double faults towards the end of the match.

"I was just persistent. Towards the end I had zoned in 100 per cent. Both of us brought an amazing energy out on the court. Felix is someone I've played a lot and I have huge respect for him."

Greek star Tsitsipas will next play emerging Italian teenager Lorenzo Musetti for a spot in the ATP 500 tournament decider.

Qualifier Musetti, who upstaged third seed Diego Schwartzman in the first round, stunned fifth seed Grigor Dimitrov 6-4 7-6 (7-3) in the final match of the day.

The 19-year-old Musetti will now contest his maiden ATP 500-level semi-final as he prepares to enter the top 100 on the men's tour after just his fourth main-draw appearance.

Alexander Zverev – the German second seed – progressed to the semi-finals with a walkover after eighth seed Casper Ruud withdrew due to a wrist injury sustained in practice.

Zverev will play countryman Dominik Koepfer in the final four after he defeated Cameron Norrie 7-5 6-4, maintaining his run of not dropping a set all tournament.
