David Goffin beat Roberto Bautista Agut in the Open Sud de France final to win his first title on the ATP Tour since 2017.

The Belgian came from a set down to prevail 5-7 6-4 6-2, securing a fourth consecutive win over Bautista Agut.

It made him just the third non-Frenchman to lift the trophy in Montpellier, following in the footsteps of Tomas Berdych and Alexander Zverev.

The world number five sent down 13 aces and converted four of his seven break points en route to his fifth tournament win.

Alexei Popyrin claimed his maiden ATP Tour title with victory over Alexander Bublik in the final of the Singapore Tennis Open.

Popyrin, who stunned Marin Cilic in the last four, triumphed 4-6 6-0 6-2.

The Australian lost only six points on his serve, wrapping up the win in 84 minutes.

"It feels unbelievable," said Popyrin. "A lot of sacrifice, a lot of dedication and a lot of hard work went into this from myself, my team and my whole entire family.

"I have done it for everybody who was involved. I am just so proud that I could actually get it done."

David Goffin moved a step closer to ending his ATP Tour title drought by seeing off the challenge of Egor Gerasimov at the Open Sud de France. 

Having previously lost in two semi-final appearances at the tournament in Montpellier, Goffin made it third time lucky as he came out on top in a deciding set against his opponent from Belarus. 

The second seed claimed the crucial break in the seventh game, then quickly consolidated his lead with an impressive hold. Gerasimov forced him to serve out for the win and Goffin duly delivered under pressure, clinching on his second match point. 

The world number 15 – who won two of his four career titles in 2017, but none since - will next face Roberto Bautista Agut, who defeated Peter Gojowczyk 7-5 6-1 after just one hour and 16 minutes on court.

At the Singapore Tennis Open, Alexei Popyrin caused an upset as he defeated Marin Cilic via a pair of tie-breaks in a hard-fought semi-final. 

Popyrin prevailed 7-6 (7-5) 7-6 (7-2) to knock out Cilic, who had survived two match points before eventually beating Kwon Soon-woo in the previous round. 

Alexander Bublik is also through to the final, guaranteeing a first-time winner on the ATP Tour at the tournament. 

Bublik made the final of the Antalya Open earlier this year but had to retire due to an ankle injury. He will hope for better fortunes on Sunday, securing another opportunity for a maiden title after battling back from a set down to see off Radu Albot. 

Rafael Nadal sailed into the second round of the Australian Open on day two before backing "humble" fellow Spaniard Carlos Alcaraz to have a "great career" following his maiden grand slam win.

Nadal cruised to a 6-3 6-4 6-1 victory over Laslo Djere on Rod Laver Arena on Tuesday and will face Michael Mmoh in round two.

The Spanish great's compatriot Alcaraz won his first major match at Melbourne Park, seeing off fellow qualifier Botic Van de Zandschulp 6-1 6-4 6-4.

Murcia native Alcaraz has been billed by Nadal's uncle and former coach, Toni Nadal, as his nephew's "natural replacement" and the 20-time grand slam champion says the 17-year-old has all the ingredients to have a great career.

The second seed said: "He's very good. He's very young. He has everything to improve in the future with his age.

"He already is where he is, and he has a lot of great things on his game. I really believe that he will have a great future because he's a good guy, humble, hard worker. He has a lot of positive things."

Daniil Medvedev outclassed Vasek Pospisil 6-2 6-2 6-4, while Stefanos Tsitsipas eased past Gilles Simon 6-1 6-2 6-1, but fellow seed David Goffin lost a five-set marathon with Alexei Popyrin.

Nadal happy to 'survive' 

Nadal missed the ATP Cup before starting his quest for a record 21st grand slam title at Melbourne Park due to muscle tightness in his back.

He was simply happy to clear the first hurdle on the second day of the tournament.

"I needed to survive today and that's what I did. I just tried to be focused all the time, tried to get through," he said.

"For me personally, [I'm] happy to be through to the second round. I did I think a good job today. Straight sets, that's what I did."

Tennys disgruntled over 'joke' of preparation

American Tennys Sandgren was among over 70 players who were locked down in a hotel for a fortnight before the tournament due to positive COVID-19 test on their flight to Australia.

Sandgren made no secret of his displeasure over the restrictions he was forced to adhere to and let his feelings be known again after the two-time quarter-finalist lost 7-5 6-1 6-1 to Alex de Minaur on John Cain Arena.

He said: "How would you imagine prepping for a hot kind of muggy day, three-out-of-five sets against a player like that, that calibre, when you can't play tennis? You can't go outside? You can't. It's impossible. It's impossible.

"So I played last week's event [the Great Ocean Road Open], which probably wasn't a good idea. It wasn't hot, it was very mild conditions, and I played two hard three-set matches and I've never been more sore in my life after the second round, and I took two days off because I couldn't walk, and then I hit a couple times before today. I mean, it's just kind of a joke of preparation. But yeah. What are you going to do?"

Alcaraz escaping social media hype

Big things are expected of teenager Alcaraz and there was more hype over his potential after an impressive first-round win.

Alcaraz just wants to do his own thing and show why the likes of Rafael and Toni Nadal speak so highly of him.

"So I try to be focus on me, not on the social media, to play my game, play in front of my team, to my team, to me, my family," he said.

"I try to, yeah, to be a part of the social media and don't hear the comparison with Rafa. Yeah, I try to do this."
