Argentina's Sebastian Baez tasted success in his home country on Sunday as he defeated Federico Coria 6-1 3-6 6-3 in the Cordoba Open final.

In the fourth ATP Tour final of his career, Baez secured his second title, showing a slight edge both in his service game and with his returns.

He rattled through the first set in just 31 minutes, winning 17 of his 20 total service points (85 per cent), while Coria could only convert at a 48 per cent rate (11 of 23).

Coria tightened things up in the second set and turned the tide, winning 81 per cent of points on his serve while Baez plummeted to 61 per cent, not allowing a single break point opportunity.

Each player created two break point chances in the deciding set, and while Coria failed to convert either, Baez got the job done at the first attempt, jumping out to an early lead and serving it out the rest of the way.

Coria shot himself in the foot with five of the six total double faults, while Baez served the only ace of the match.

The 22-year-old Baez, who entered the contest ranked 47th in the world, will now climb into the top 40 as he edges closer to his career-best ranking of 31st.

Wu Yibing triumphed in an extraordinary final against local hero John Isner at the Dallas Open to become China's first winner of a singles title at ATP tour level in the Open Era.

Isner served 44 aces but still lost, with the 37-year-old going down 6-7 (4-7) 7-6 (7-3) 7-6 (14-12) in a match that saw neither player break serve at any point, climaxing in a marathon tie-break.

Former world number eight Isner was chasing a 17th singles title, and a first at an indoor tournament, and he saw a match point slide by at 6-5 in the second set.

Wu resisted one of the best serves in tennis history and took the match all the way. The first 22 points of the third-set tie-break went with serve, before Wu hit a super backhand winner to interrupt the sequence. Incredibly, Isner won the next rally to bring it back on serve, but the match then got away from him, and a stray forehand from the American gave Wu the title.

Dallas resident Isner, famed for his 11 hours and five minutes win over Nicolas Mahut at Wimbledon in 2010, featuring a 70-68 final set, said of this loss: "That kind of stunk for me."

Wu said: "It's a very tough match today. I'm not even moving when he serves. I made history here for my country. I'm very proud of myself."

Jannik Sinner claimed his first title of the season with a 7-6 (7-3) 6-3 victory over Maxime Cressy at the Open Sud de France.

Cressy defeated top seed Holger Rune in the semi-finals but could not repeat that level of performance against Sinner, who is set to rise to 14th in the ATP rankings.

Sinner is the first Italian champion in the history of the tournament, having failed to win a match in his previous two appearances in Montpellier.

He has now collected seven Tour-level titles, with six of those coming on hard courts.

"To be honest, the first key was to hold the serve. In the tie-break I knew he may miss something," said Sinner, who saved all three break points he offered to his American opponent.

"I tried to keep my serve, which I have done, so I am very happy about the first set.

"The second set was a little bit different. I had a couple of good chances but he then served very well.

"I am very happy I broke him here and then I served very well at the end of match."

Sinner claimed two early mini breaks in the first-set tie-break to nose into a 4-0 lead, holding his nerve to win the set at the first time of asking.

A crucial break in the second came in the eighth game, with Sinner clinching victory when Cressy sent a weak volley into the net.

There is guaranteed to be an Argentine winner of the Cordoba Open on Saturday, while Taylor Fritz was stunned in Dallas.

Federico Coria, seeded sixth, overcame reigning champion and 2021 runner-up Albert Ramos-Vinolas 6-4 7-6 (7-2) after over two-and-a-half hours of action.

The world number 67, who is into his second ATP Tour-level final and is set to rise into the top 50 of the rankings, has dropped just a single set in the tournament.

Sebastian Baez, eight years Coria's junior, is aiming for his second title after winning in Estoril last year.

The 22-year-old fourth seed defeated Hugo Dellien 6-4 6-4.

This will be the fourth singles final of Baez's career, though his first on home soil.

"It means a lot, but [it brings] confidence," said Baez.

"I have my people here, my friends, my family, everything, so that is a big motivation for me."

While Coria and Baez have just five previous final appearances between them, John Isner advanced to a 31st Tour-level showdown of his career as he beat fellow American J.J. Wolff at the Dallas Open.

Playing in his home city, 37-year-old Isner came from behind to prevail 3-6 7-5 7-6 (7-4).

Isner offered up eight break points, but saved seven of them to frustrate Wolff.

"I saved a lot of break points with unreturnable serves," Isner said. "Without that I would have been dusted off the court 6-3, 6-4. I'm of course very fortunate to have that weapon in my pocket, and I needed every bit of it today.

"It was an absolute battle, so I'm pretty tired. But I'm absolutely ecstatic to be in the final tomorrow here in Dallas."

Asked how he was faring up after his long tussle with Wolff, Isner quipped: "Truthfully, it feels terrible right now. I'm 38 in April. It's not getting any easier. I started off a little slow, a little sluggish, but in the third set I actually felt the best I felt the whole match.

"I had a lot of adrenaline there at the end and I was able to hold my nerve and win. Right now the name of the game is recovery."

Isner will be the favourite in the final, after top seed Fritz surrendered a lead in a 6-7 (3-7) 7-5 6-4 loss to Wu Yibing.

Maxime Cressy sprang a shock by beating top seed Holger Rune to reach the Open Sud de France final, where Jannik Sinner awaits him.

Paris-born American Cressy won 7-5 6-7 (3-7) 7-6 (7-4) in a little over two and a half hours, countering 10 double faults with 15 aces on his way to victory.

Rune, the Danish 19-year-old who sits ninth in the world rankings, had won his three previous matches against Cressy, including a second-round clash at the Australian Open last month, but he could not extend that dominance at the indoor event in Montpellier.

It means Cressy faces second seed Sinner, a player he lost to at a low-level tournament in Lexington in 2019, their only past meeting.

Sinner beat 18-year-old French wildcard Arthur Fils in Saturday's first semi-final, ending the teenager's eye-catching run with a 7-5 6-2 victory.

Fils had beaten Richard Gasquet and Roberto Bautista Agut on his way to the last four but found world number 17 Sinner was more than his match.

Last year saw Sinner reach just one ATP final, taking a title on clay in Umag, after making it through to five title matches in the 2021 season.

He had his best year at the grand slams, however, reaching quarter-finals at three of the four majors.

Cressy recognises the threat posed by the Italian, saying in an on-court interview: "Jannik Sinner is an incredible player, just like Holger Rune and everyone else in the tournament. I believe you've just got to bring your 'A' game every time and I'm really looking forward to it."

Competing well in France has been pleasing for Cressy, who is set to climb from 51st in the rankings and into the top 40 on Monday.

"I lived and grew up here, and I'm extremely happy," Cressy said.

World number eight Taylor Fritz is two wins away from his first title of the season after surviving a tough test against Marcos Giron 7-6 (9-7) 3-6 6-3 in Friday's quarter-final at the Dallas Open.

Fritz, who at 25-years-old is seeking the fifth ATP singles title of his career, allowed seventh-seed Giron only one break point opportunity for the entire match. Fritz himself only created two such opportunities, and further illustrating the closely-fought nature of the battle, Fritz edged the total point count 86-85.

With the win, Fritz booked his place against China's Yibing Wu in the semi-final after the 23-year-old defeated 34-year-old French veteran Adrian Mannarino 6-3 6-4.

The other semi-final will be an all-American showdown after J.J. Wolf upset second seed Frances Tiafoe 4-6 6-3 6-4, and 37-year-old John Isner proved too much for Ecuador's Emilio Gomez in a 7-6 (10-8) 7-5 victory.

Meanwhile, Spain's Albert Ramos-Vinolas is one match away from a final in his home country after defeating Joao Sousa 6-4 2-6 6-1 in the quarter-final of the Cordoba Open.

Ramos-Vinolas will play Argentina's Federico Coria for a spot in the decider after he emerged victorious 6-3 3-0 (ret) against compatriot Francisco Cerundolo.

Heading into the quarter-finals, Francisco and his brother Juan Manuel Cerundolo were on a collision course to meet in the final, but now both are eliminated after 21-year-old Juan Manuel fell 6-7 (5-7) 6-4 6-0 to Bolivia's Hugo Dellien.

Dellien will play fourth seed Sebastian Baez in the other semi-final after eliminating Chile's Tomas Barrios Vera 6-1 3-6 6-1.

Open Sud de France top seed Holger Rune stayed on course to make the final in Montpellier after a straight-sets defeat of Gregoire Barrere.

Last year's Paris Masters champion Rune, who is in the hunt for his first title of the season, beat the Frenchman 7-6 (7-2) 7-6 (7-5) and is yet to drop a set in the tournament.

The 19-year-old looks sharp, but so too does Jannik Sinner. Two years Rune's senior, the Italian made light work of his good friend and compatriot Lorenzo Sonego on Friday.

Sinner took just over 90 minutes to triumph 6-4 6-2 and tee up a semi-final with history-making 18-year-old Arthur Fils.

Fils, the world number 163, beat Quentin Halys to become the youngest Frenchman to reach a tour-level semi-final since Richard Gasquet in 2004.

"I have seen him [Fils] play here at this tournament," Sinner said of Fils, as quoted by the ATP Tour's official website.

"He is very strong physically already. He understands the game very well. He started off the year very well, so it is going to be an interesting match for sure."

Sinner will be the favourite despite Fils' hot streak, while Rune will go up against Maxime Cressy in a rematch of their Australian Open second-round match.

Cressy went down 7-5 6-4 6-4 in that meeting in Melbourne last month, though has the chance for revenge after seeing off Borna Coric 7-6 (7-2) 6-4.

Top seed and world number eight Taylor Fritz made a winning start to his Dallas Open campaign on Thursday, eliminating Jack Sock 7-6 (7-5) 6-4.

In an all-American showdown, Fritz played a near-flawless match, converting 91 per cent of his accurate first serves into points while not allowing Sock a single break point opportunity.

Fritz will face seventh seed Marcos Giron in the quarter-final after the American defeated Germany's Oscar Otte 6-4 6-3, while the USA's John Isner also advanced past Germany's Daniel Altmaier 6-3 7-6 (7-1).

Earlier in the day, Serbian fourth seed Miomir Kecmanovic was upset by Ecuador's Emilio Gomez 2-6 7-6 (7-4) 6-4 to earn a crack at Isner in the quarter-finals.

Meanwhile, the top seed fell at the Cordoba Open as red-hot 21-year-old Juan Manuel Cerundolo shocked his Argentinian compatriot Diego Schwartzman 7-6 (8-6) 6-1.

It continues a remarkable run for Cerundolo – the defending champion in Cordoba – who has begun 2023 with 14 wins from his first 15 matches, while his older brother Francisco Cerundolo also advanced with a 6-3 3-6 7-5 win over Federico Delbonis.

If the two brothers both win their next two matches, they will meet in the final.

Holger Rune made a winning start at Open Sud de France after defeating Marc-Andrea Huesler 7-6 (7-5) 6-2 to reach the quarter-finals in Montpellier.

Appearing as the top seed at an ATP event for the first time, Rune had lost both his previous meetings with Huesler, including last season's Sofia Open.

However, the world number nine made it third time lucky to set up a last-eight clash with Gregoire Barrere, who beat Nikoloz Basilashvili in straight sets.

Meanwhile, third seed Borna Coric is now just one win away from securing a return to the top 20 in the ATP rankings. The world number 23 – and reigning Cincinnati champion –saw off Arthur Rinderknech 6-3 7-5.

Although, there was no joy for Alejandro Davidovich Fokina. The fifth seed was ousted 6-3 6-3 by world number 70 Quentin Halys, who claimed only his second top-50 career win in 20 attempts.

Seventh seed Emil Ruusuvuori was also eliminated in straight sets by Maxime Cressy, but Lorenzo Sonego overcame Filip Krajinovic to book a quarter-final date with Jannik Sinner.

Denis Shapovalov suffered defeat at the hands of China's fast-rising Wu Yibing at the Dallas Open.

Wu landed a 7-6 (7-1) 6-4 win against the Canadian Davis Cup winner and former top-10 player in their second-round contest.

World number 97 Wu, who this week became China's second player to reach the ATP top 100, has surged from 1,869th on the ranking list last April and believes he can crack the top 30 by the end of the year.

Speaking after getting the better of Shapovalov, who stands at 27th in the rankings, Wu said: "I've been playing great tennis the past few months. Hopefully I can keep playing good."

Frances Tiafoe cruised into the quarter-finals with a 6-1 6-3 win over fellow American Mackenzie McDonald.

Second seed Tiafoe was playing for the first time since his third-round elimination to Karen Khachanov at the Australian Open last month.

He faced just one break point in the entire match and needed just 59 minutes to deal with the world number 59.

J.J. Wolf, seeded sixth, will face Tiafoe in the last eight after he saw off Romania's Radu Albot in a 6-3 7-6 (7-5) win.

At the Cordoba Open, fifth seed Pedro Cachin was the biggest casualty on Wednesday as he was beaten 6-3 6-4 by Bolivian qualifier Hugo Dellien.

Seventh seed Pedro Martinez was also ousted in the first round, while Bernabe Zapata Miralles was sent packing by Tomas Barrios Vera in the last 16, losing 5-7 6-4 6-3.

Fourth seed Sebastian Baez had no such issues with Italy's Luciano Darderi, however, reaching the quarter-finals as a 6-3 6-4 winner.

Marc-Andrea Huesler will face top seed Holger Rune in the second round of the Open Sud de France after coming through a battle with teenager Luca Van Assche.

Huesler arrived in Montpellier on a high from victories over German duo Alexander Zverev and Oscar Otte for Switzerland in Davis Cup qualifiers last weekend.

The left-hander saw off 18-year-old Frenchman Van Assche 6-3 3-6 6-3 and will get a chance to improve his perfect record against Rune to 3-0.

Italian Lorenzo Sonego sent eighth seed Benjamin Bonzi packing with a 6-4 6-3 win, while French-born American Maxime Cressy progressed with a 6-3 6-2 defeat of Antoine Bellier.

Arthur Rinderknech and Quentin Halys also advanced on home soil, along with Marton Fucsovics and Filip Krajinovic.

Teenage wildcard Arthur Fils claimed his first ATP Tour victory to knock three-time champion Richard Gasquet out of the Open Sud de France.

The 18-year-old Fils, half the age of his opponent, won the first-round match against his fellow Frenchman 7-5 7-5 in Montpellier.

Fils will face another battle between youth and experience when he takes on Spaniard Roberto Bautista Agut in round two.

The 163-ranked Fils served eight aces and broke Gasquet four times to move into the next round

Nikoloz Basilashvili will face either defending champion Alexander Bublik or Gregoire Barrere in the last 16 after beating Constant Lestienne 6-3 (7-3) 7-5 6-2 in Monday's other match.

At the Auckland Open, second-seed Briton Cameron Norrie beat American Marcos Giron 6-1 6-7 (5-7) 6-2 to set up a last-four clash with another player from the USA, Jenson Brooksby, who edged past France's Quentin Halys 7-6 (7-3) 7-6 (7-2).

The other semi-final will be an all-French battle between Richard Gasquet and Constant Lestienne, who both came from a set down to see off David Goffin and Laslo Djere respectively.

Thanasi Kokkinakis is on a roll again at the Adelaide International 2 where the hometown hero and defending champion marched into the semi-finals on just two hours' sleep.

The Australian wildcard saw off Serbian sixth seed Miomir Kecmanovic 6-3 6-7 (4-7) 6-1 on Thursday to set up a semi-final against Spain's Roberto Bautista Agut.

Kokkinakis had a stellar run to the title at this tournament 12 months ago, beating John Isner and Marin Cilic before knocking over Frenchman Arthur Rinderknech in the final.

A first-round exit followed at the Australian Open, although he memorably won the doubles title with Nick Kyrgios. Kokkinakis struggled for the rest of the year, with his ranking currently at 110.

Kokkinakis said after his latest win: "I didn't sleep much last night. I reckon I got to sleep at about five and maybe slept for a couple of hours.

"I just couldn't sleep for whatever reason, so I was trying to conserve energy. I didn't want to use it too much. I had a couple of Monsters [energy drinks] before I started and tried to get going.

"When I'm serving well my whole game follows, and then when my forehand gets going I think I've been hitting my backhand really well this week. If I'm doing those three things, it's a good recipe.

"I grew up on this court when I was eight, nine, 10 years old. I showed up last year, and hopefully I can ride the wave with you guys and keep it going."

Fourth seed Bautista Agut beat compatriot Alejandro Davidovich Fokina 6-3 6-2, while the other Adelaide semi-final will see British player Jack Draper tackle South Korean Kwon Soon-woo.

Draper, who has been drawn to face Rafael Nadal in round one of the Australian Open, beat Russian third seed Karen Khachanov 6-4 7-6 (7-3), while Kwon saw off Swedish qualifier Mikael Ymer 6-1 6-2.

At the Auckland Open, second-seed Briton Cameron Norrie beat American Marcos Giron 6-1 6-7 (5-7) 6-2 to set up a last-four clash with another player from the USA, Jenson Brooksby, who edged past France's Quentin Halys 7-6 (7-3) 7-6 (7-2).

The other semi-final will be an all-French battle between Richard Gasquet and Constant Lestienne, who both came from a set down to see off David Goffin and Laslo Djere respectively.

Gregoire Barrere withstood a barrage of aces from John Isner and a change of court triggered by Cyclone Hale as he upset the American sixth seed at the Auckland Open.

French qualifier Barrere and US veteran Isner were forced indoors by the adverse weather threat in New Zealand, with the entire Tuesday schedule taking place on inside courts and without spectators.

Despite Isner rifling down 28 aces to move 10 away from becoming the first man to post 14,000 in ATP tour and grand slam events, Barrere stuck with him and pulled off a 6-7 (3-7) 7-6 (7-5) 6-3 victory.

He snatched the only break of the match in game eight of the deciding set, before serving out for victory, with the world number 88 firing down 10 aces himself across the contest.

Argentine seventh seed Sebastian Baez also fell at the last-32 stage, bowing out 7-6 (7-1) 6-1 to American wildcard Ben Shelton.

Serbian Laslo Djere set up a second-round clash with top seed Casper Ruud by edging out Spain's Jaume Munar 3-6 6-1 7-6 (7-4), while Czech Jiri Lehecka will face second seed Cameron Norrie next after sinking Brazilian fellow qualifier Thiago Monteiro 6-3 7-5.

Ruud and Norrie received first-round byes.

At Adelaide International 2, American eighth seed Tommy Paul battled past Australian Christopher O'Connell 6-4 7-5, setting up an appetising second-round clash with Britain's Jack Draper, who won through on Monday.

There was a home success for the Australian crowd to cheer, though, as qualifier John Millman, who beat Roger Federer at the 2018 US Open, this time dug deep for a 4-6 6-3 7-6 (8-6) win against Spain's Albert Ramos-Vinolas.

David Goffin got off the mark with his first victory of 2023 with a straight-sets win over fifth seed Alexander Bublik in round one of the Auckland Open.

The Belgian lost both matches at the inaugural United Cup last week, but he saw off Bublik 6-3 6-4 in 74 minutes to reach the last 16 in New Zealand.

Another seeded player fell at the first hurdle on Monday as Adrian Mannarino lost 6-4 7-6 (7-4) to J.J. Wolf.

Richard Gasquet advanced with a 6-3 6-1 win over wild card Kiranpal Pannu, while Jenson Brooksby beat Fabio Fognini 6-7 (2-7) 6-1 6-3 and will now face Diego Schwartzman.

At the Adelaide International 2, fifth seed Dan Evans suffered a 7-5 7-5 defeat to Mackenzie McDonald.

Fellow seeds Alejandro Davidovich Fokina and Miomir Kecmanovic overcame Brandon Nakashima and Kyle Edmund respectively.
