Novak Djokovic will tackle teenage rising star Jannik Sinner for the first time in a tantalising clash of tennis generations on Wednesday at the Monte Carlo Masters.

World number one Djokovic is returning to action this week, having taken time away from the tour since banking an 18th grand slam title by winning the Australian Open in February.

He received a first-round bye, but waiting for him in the last 32 is Sinner, who on Tuesday saw off 2017 Monte Carlo runner-up Albert Ramos-Vinolas 6-3 6-4, again illustrating the 19-year-old Italian's great potential.

World number 22 Sinner is the only teenager ranked inside the top 80 in the men's game and is coming off his first run to a Masters final, at the Miami Open.

The switch from hard courts to clay is one that Sinner is having to deal with, and seeing off a specialist on the surface in round one represents an impressive start, although facing two-time former champion Djokovic will be a step up.

"It's always good for me to see what I can do on clay," Sinner said, quoted on the ATP website. "Obviously, I am not in the best form on clay now for the first week.

"But I think today was a solid match from my side. It was not easy. He's not giving [away] one point, so you have to stay there the whole match. I think I played a good match from my side."

Greek fourth seed Stefanos Tsitsipas reached the last 16 with a 6-3 6-4 win over Russian Aslan Karatsev, but there was disappointment at the same stage for Italian eighth seed Matteo Berrettini, beaten 7-5 6-3 by Spain's Alejandro Davidovich Fokina. Those were the only second-round matches of the day.

Surprise Miami champion Hubert Hurkacz made a winning start, battling to a 6-3 3-6 6-3 first-round success against Italian qualifier Thomas Fabbiano to reach round two.

Roberto Bautista Agut, Grigor Dimitrov, Pablo Carreno Busta and Fabio Fognini each booked places in round two thanks to straight-sets wins.

Qualifier Federico Delbonis was a 7-5 6-1 victor over France's Adrian Mannarino, meaning the Argentinian faces the ultimate test in clay-court tennis next, a tussle with Rafael Nadal, the 11-time former champion in Monte Carlo.

Nadal has won all four of their previous matches, and their fifth encounter will immediately follow the Djokovic-Sinner match on Wednesday.

Hubert Hurkacz made history after trumping Jannik Sinner in the Miami Open final for his first ATP 1000 title.

Hurkacz became Poland's first ATP 1000 champion thanks to his 7-6 (7-4) 6-4 win over teenage sensation Sinner in Miami on Sunday.

Second seed Stefanos Tsitsipas, fourth seed Andrey Rublev, sixth seed Denis Shapovalov and 12th seed Milos Raonic were all upstaged by Hurkacz en route to the decider.

Hurkacz – the 26th seed – capped his memorable run with an impressive win against 19-year-old Italian and occasional doubles partner Sinner following one hour, 45 minutes on court.

Set to break into the ATP Tour's top 20 for the first time in his career, moving from 37 to a career-high 16th in the world, Hurkacz became the fourth player to win his first ATP 1000 trophy via the Miami Open since 1990 – following in the footsteps of John Isner (2018), Novak Djokovic (2007) and Andre Agassi (1990).

"I played [some] of the best tennis I've ever played," Hurkacz, who converted seven of 11 break-point chances against ATP 1000 finals debutant Sinner, said.

"I was solid throughout the whole tournament, and I was able to get through each round, [and] was even more pumped for the next round. I think that's something special for me.

"My tennis is getting better. We work hard with my coach, [Craig Boynton], and I'm super happy that it happened here. We still need to improve a couple of things and just try to get better each day."

Hurkacz became the first player this ATP Tour season to win two titles, having already claimed the Delray Beach Open.

The 24-year-old added: "Last year I spent so much time in Florida. I was here like almost half of the year.

"We were working pretty hard, and I think I'm used to the conditions. I think [that's] been part of the success I had here in Florida."

Hubert Hurkacz has recorded back-to-back top 10 wins to move a step closer to his maiden ATP Masters 1000 trophy with a hard-fought straight-sets win over Andrey Rublev at the Miami Open on Friday night.

The 26th seeded Pole knocked off in-form fourth seed Rublev 6-3 6-4 to book a spot in Sunday's final where he will play teenage 21st seed Jannik Sinner who defeated Roberto Bautista Agut earlier in the day.

The 24-year-old from Wroclaw had beaten second seed Stefanos Tsitsipas in the quarter-finals and continued that strong form by never allowing Rublev to settle into his game.

"It means a lot, especially after winning a title at the beginning of the year, I had a couple of rough matches," Hurkacz said in his on-court interview, referring to his January win at the Delray Beach Open in Florida.

"I’m so happy that I came over and I was still trying to improve my game and trying to be a better player. This is really huge for me."

The 23-year-old Russian had won 16 matches this calendar year including taking out last month's Rotterdam Open.

Rublev had also not lost a set all tournament and only been broken twice, yet Hurkacz broke serve three times.

The Pole also hit 25 winners and showed determination under pressure, when Rublev had a break point at 5-4 in the second set, before saving it in an epic rally and winning the game to secure the match.

World number eight Rublev said: "Today was not my day. Hurkacz played really well and he deserved to win… Now it's time to go back to work hard to be ready for the clay season."

"It’s [been a] great week for me. I did my first semis [at an ATP Masters 1000]. I'm playing really consistent. Every week I go deep in the tournament."

Sinner, 19, won a three-set match against Bautista Agut to book his spot in the decider earlier on Friday.

The young Italian world number 31 and Hurkacz know each other well.

"We played doubles together last week in Dubai,"Hurkacz said. "Now we’re playing in the final of a Masters 1000 event, so it’s going to be a fun match."

Second seed Stefanos Tsitsipas has blown a strong position to be knocked out of the Miami Open by world number 37 Hubert Hurkacz in three sets on Thursday night.

The Polish 26th seed lost the first set and trailed 0-2 in the second with Tsitsipas having two break points, before fighting back for an outstanding 2-6 6-3 6-4 triumph.

The victory seals Hurkacz's place in his first-ever Masters 1000 semi-final where he will face Russian fourth seed Andrey Rublev.

On Thursday night, Rublev won 7-5 7-6 (9-7) over Sebastian Korda, ending the young American's exceptional run in Miami.

Tsitsipas's demise was the major story on Thursday, having only dropped one set in his previous three matches in Miami.

The Greek world number five was in form, having made February's Australian Open semi-finals and last week's Mexican Open final.

Tsitsipas was in control until Hurkacz dialed up his aggression in the second, producing a brilliant flick after the Greek's volley to take advantage at 2-2.

Hurkacz got the crucial break at 2-2 in the third when the Greek coughed up a mistake by missing a routine smash.

The 24-year-old Pole also sent down 15 aces in a breakthrough win.

"It is so big," Hurkacz said in his on-court interview about reaching his maiden Masters 1000 semi-final.

"I was trying to keep fighting and that’s what I did. [I am] super pumped and happy that I was able to turn this match around.

"He was returning very well and I had to play a lot of rallies. At the beginning of the match, I tried to go for too much, so then I was trying to adapt my game a little bit."

Rublev claimed his 20th ATP Tour win for the calendar year, the most of any player ahead of Daniil Medvedev and Tsitsipas with 17, to book his semi-final spot against Hurkacz.

The defeat ended 20-year-old Florida resident Korda's superb run, where he claimed his first top 20 win against Fabio Fognini and first top 10 victory against Diego Schwartzman.

Egor Gerasimov followed up his win over Andy Murray in Montpellier by powering past a man who once played second fiddle to the Scot.

The Belarusian saw off Aljaz Bedene, with a 6-4 7-6 (7-4) win carrying him through to the quarter-finals of the Open Sud de France.

Bedene was British number two to Murray heading into Wimbledon in 2016, when the Scot won his third grand slam title, but has since reverted to representing his native Slovenia.

He put up a fight against Gerasimov, who sank Murray in straight sets on Tuesday, but the 28-year-old from Minsk took three of his five break-point opportunities and held his nerve in the tie-break to advance.

The success for Gerasimov sets up a last-eight clash with Spain's Alejandro Davidovich Fokina, who scored a fine 7-5 6-2 win over Polish fourth seed Hubert Hurkacz.

Top seed and world number 13 Roberto Bautista Agut raced to a 6-0 6-3 victory over French qualifier Gregoire Barrere, but Croatian third seed Dusan Lajovic tumbled out, losing to Dennis Novak in straight sets.

At the Singapore Open, second seed John Millman fell by the wayside, the Australian slumping 6-4 6-1 to compatriot Matthew Ebden.

French top seed Adrian Mannarino encountered no such problems, ending the hopes of Roberto Marcora with a 6-3 7-5 win to join Ebden in the quarter-finals.
