Italian Camila Giorgi knocked out another seed on her way to clinching a spot in the Merida Open final where she will face Sweden's Rebecca Peterson.

Giorgi triumphed 7-5 7-6 (7-2) over fourth seed Katerina Siniakova in two hours and 12 minutes in Saturday's semi-final in Akron.

The Italian world number 68 had routed second seed Sloane Stephens 6-0 6-0 on Friday to earn her spot in the last four.

Swedish qualifier Peterson secured her final berth with a 6-2 6-7 (4-7) 6-4 over American Caty McNally.

The topsy-turvy match lasted almost three hours, with Peterson fighting back from 4-0 down in the third set by winning the final six games for victory.

Top seed Carlos Alcaraz fought back from a set down against Nicolas Jarry to keep alive his Rio Open title defence by booking a spot in Sunday's final.

The Spanish 19-year-old triumphed 6-7 (2-7) 7-5 6-0 to win in two hours and 43 minutes in Saturday's semi-final.

Alcaraz raced away with the match with a third-set bagel in 32 minutes after both of the first two sets lasted more than an hour each.

The 2022 US Open champion produced one of the shots of the season to go 2-0 up in the third set, producing a remarkable running pass down the line.

Alcaraz had undergone treatment on his upper left leg late in the second set at 5-5 but showed off his toughness to reel off eight straight games.

"I'm so proud of myself," Alcaraz said, having only just returned from injury in last week's Argentina Open which he won. "To be in a final again in my second tournament is a really special moment for me... I couldn't ask for a better start of 2023."

The Spaniard will take on second seed Cameron Norrie in the decider, after the Briton won 6-2 3-6 7-6 (7-3) over Bernabe Zapata Miralles in Saturday's other semi-final.

Norrie needed two hours and 32 minutes to get the better of Zapata Miralles, meaning he has won 13 of his past 15 tour-level semi-finals.

Alcaraz and Norrie faced off in last week's Argentina Open final, which the Spaniard won in straight sets.

Top seed Hubert Hurkacz saw off a spirited Alexander Bublik in straight sets to seal his place in the final of the Open 13 Provence with a 6-4 7-6 (7-4) win.

The world number 11 wrapped up victory in his semi-final in Marseille without being taken to a deciding third set for the first time during his tournament run.

But he was still forced to fight for the result, after unseeded Kazakhstani Bublik pushed him hard in their encounter.

Hurkacz only broke serve once during the first set and had to hold his nerve in a second-set tie-break to finish the job.

He will face a homegrown opponent in Benjamin Bonzi in the final, after the latter won an all-French last-four encounter with wild card Arthur Fils.

The former saw off his fellow countryman 6-4 6-4 in a straight-sets triumph of his own.

Barbora Krejcikova stunned Iga Swiatek to win the Dubai Tennis Championships, cruising past the world number one in straight sets to clinch her first WTA 1000 title. 

By following up victories over Aryna Sabalenka and Jessica Pegula with a ruthless 6-4 6-2 dismantling of Swiatek, Krejcikova became just the fifth woman to beat each of the world's top three players at a single tournament in the last 40 years.

Krejcikova entered Saturday's meeting as the only player to have beaten Swiatek in her eight hard-court finals at tour level, having done so at the Ostrava Open last October.

The Czech looked to be drawing on that experience as she made a flying start, breaking in the opening game through a well-struck backhand. 

Though Swiatek responded with a break of her own in the sixth game, a rare double fault from the Pole saw the momentum swing Krejcikova's way.

Another excellent backhand return gave Krejcikova the opening set's decisive break, after which a visibly frustrated Swiatek was handed a time violation by the umpire.

Things did not get much better from there for the three-time grand slam winner, with a series of masterful returns helping Krejcikova seal two dominant breaks before wrapping things up.

Having clinched a highly impressive win within 91 minutes, Krejcikova told Amazon Prime Video: "It means a lot. 

"It was a great week for me, I was improving with every single game and today, I think I showed my best. 

"I really have to admire Iga for what she is doing. To me, she is a big inspiration and she motivates me every day. It was a great final and I'm definitely happy with the result."

Daniil Medvedev defied Andy Murray in the Qatar Open final to clinch a second title in seven days as the resurgent Russian won the battle of former world number ones.

In-form Medvedev scored a 6-4 6-4 victory on Saturday as he followed up last Sunday's title in Rotterdam with another trophy success.

Three-time grand slam winner Murray, set to jump 18 places to 52nd in the new rankings, had saved eight match points en route to the Doha final.

He pushed Medvedev hard but could not get the better of a player who will nudge up one spot to seventh in the rankings on Monday.

Murray came back from 0-40 in the opening game to force deuce, but he could not hold serve, and Medvedev soon broke again to lead 4-1.

But back came Murray, and the Briton had a break point to square up the opener at 4-4, only for Medvedev to cling on.

The second set also began with Murray dropping serve, but the 35-year-old levelled up at 3-3 with a backhand winner at the end of a terrific rally.

That raised his hopes of a full-scale fightback and a third title success at this event, plus a first tournament victory since 2019 in Antwerp, but Murray was broken from 40-0 in the ninth game, and that looked to end his hopes.

Murray saved a ninth match point of the week, albeit thanks to a double fault from his opponent, but the Scot could not do so for a 10th time, with a lob from Medvedev giving him a big win and the 17th tour-level title of his career.

Medvedev, the 2021 US Open champion, told Amazon Prime Video in a courtside interview: "It was a very tough match. I'm happy to win, today was a big fight.

"Both of us sometimes were playing bad, then suddenly both of us were playing amazing, and I'm happy to win.

"It was tough for Andy to put the ball through me many times. Now it has to continue, so I'm going to try for as long as I can."

The top two seeds at the Rio Open remain on a collision course after both Carlos Alcaraz and Cameron Norrie advanced to the semi-finals on Friday.

World number two and top overall seed Alcaraz was strong in his 6-4 7-6 (7-0) victory over Serbia's Dusan Lajovic, improving his unbeaten record in 2023 to 6-0.

Alcaraz has his eyes set on his second title win in a row after also emerging triumphant in last week's Argentina Open.

Meanwhile, Norrie had to fight back from an early deficit to eliminate Hugo Delien 4-6 6-1 6-4, with the world number 13 and second seed now boasting eight wins from his past nine matches. The only loss during that stretch was to Alcaraz in the Argentina Open decider.

For a chance to avenge that loss, Norrie will have to beat Bernabe Zapata Miralles after he overcame Albert Ramos-Vinolas 6-4 2-6 6-4 in an all-Spanish quarter-final.

Alcaraz will contend with Nicolas Jarry, after the unseeded Chilean knocked out his second seeded opponent of the tournament, this time getting the better of Sebastian Baez 6-3 7-6 (7-3).

Andy Murray will play Daniil Medvedev in the Qatar Open final after the 35-year-old came through yet another lengthy contest in his semi-final against Jiri Lehecka.

Murray appeared to be on course for a routine win after taking the first set 6-0, but was broken early in the second, eventually losing 6-3 to take him to a fourth three-set contest in four matches this week in Doha.

Lehecka should have won a hard-fought decider when 5-4 and 40-0 up on his own serve, but Murray's trademark resilience saw him break back despite facing five match points against, before ultimately winning the tie-break 8-6.

"I don't know how I managed to turn that match around," Murray said after the win. "In the 5-4 game, I think I played most of the match points really well. He missed one bad shot on the deuce point in that game at 5-4, but I played the match points pretty well.

"It's been an amazing start to the year. I have never experienced this in my whole career, like this many matches... It was sort of looking [like it might be a quicker match] for 30 minutes and then it turned into something completely different. Yeah, just amazing that I managed to turn that around."

Murray equalled Jimmy Connors for the fifth-most ATP hard court wins in the Open Era (489), and will play Medvedev in the final after the Russian's 6-4 7-6 (9-7) win against Felix Auger-Aliassime.

The Canadian had three set points in the second set tie-break to try and force a decider, but Medvedev showed determination to turn it around and seal his place against Murray in the final.

At the Open 13 Provence, number one seed Hubert Hurkacz is through to face Alexander Bublik in the semi-finals, with both also having to come through three-set matches in a deciding tie-break.

Hurkacz was finally able to overcome Mikael Ymer 6-3 3-6 7-6 (8-6) before Bublik defeated Grigor Dimitrov 7-5 3-6 7-6 (8-6).

Third seed Alex de Minaur was shocked by Benjamin Bonzi, who broke the world number 23 four times on his way to a 6-2 6-4 victory to avenge his third-round defeat at the Australian Open.

Bonzi will meet qualifier Arthur Fils in the final four after the French 18-year-old beat former world number three Stan Wawrinka 6-2 6-3 to reach a second straight tour-level semi-final.

Barbora Krejcikova will play Iga Swiatek for the Dubai Tennis Championships title after settling a see-saw semi-final against Jessica Pegula in ruthless fashion.

Having seen Swiatek brush aside Coco Gauff in straight sets in the first match of the day, Krejcikova would have been confident of doing likewise after taking the opener against Pegula.

Third seed Pegula battled back to take the second set, though, and the American appeared to have momentum on her side, only to bow out in a one-sided decider, losing 6-1 5-7 6-0 for her first defeat to Krejcikova.

The pair's only prior meeting had been a straight-sets win for Pegula at the Australian Open earlier this year.

Pegula's sole other tournament since Melbourne had ended in similar circumstances to this one, with a 6-3 6-0 crushing at the hands of Swiatek in the final of last week's Qatar Open. The Pole is who Krejcikova must play next.

Krejcikova is the first player since Svetlana Kuznetsova in Cincinnati in 2019 to beat two top-three opponents at the same WTA 1000 tournament.

Yet after seeing off number two Aryna Sabalenka in the quarter-finals and number three Pegula in the semis, she faces the world number one in the final.

Swiatek has had a rather more straightforward path, granted a walkover in the last eight and then, on Friday, playing Gauff, who she continues to dominate.

The Pole is now 6-0 across her career against Gauff, winning all of those matches in straight sets.

Gauff at least made Swiatek work a little harder than she has in many recent matches, going down 6-4 6-2 – the first match since Melbourne in which the number one has not won a set either 6-0 or 6-1, piling up the 'bagels' and 'breadsticks'.

Swiatek is 2-1 against Krejcikova for her career, although the Czech won their most recent meeting and their only encounter in a final in Ostrava last year.

World number two Carlos Alcaraz had to come from a set behind to defeat Fabio Fognini 6-7 (5-7) 6-2 6-4 on Thursday to advance to the Rio Open quarter-final.

The 19-year-old phenom has now won all five of his matches in 2023 after winning last week's Argentina Open, and the 2022 Rio champion is now three wins away from defending his title at South America's only ATP 500 event.

Against Fognini, Alcaraz lost the first set despite creating 11 break point opportunities, as his Italian opponent converted all four of his own chances in a back-and-forth battle. 

The Spaniard tightened up his service game down the stretch, only allowing Fognini one break point opportunity from the second and third frames combined, and he will now play Dusan Lajovic following his 6-2 6-4 win against Serbian compatriot Laslo Djere.

Chile's Nicolas Jarry is still yet to lose a set in the tournament, following up his impressive upset of third seed Lorenzo Musetti with a 6-2 6-2 triumph over Pedro Martinez.

Jarry will get a crack at another seeded opponent next when he takes on Argentina's sixth seed Sebastian Baez, who emerged victorious 7-5 7-6 (8-6) after two gruelling sets against Peru's Juan Pablo Varillas.

Fourth seed Francisco Cerundolo was eliminated 6-1 4-6 6-1 by Bernabe Zapata Miralles, who will meet Albert Ramos-Vinolas in an all-Spanish quarter-final after he fought off Daniel Elahi Galan 6-2 6-4.

Andy Murray and Daniil Medvedev sealed their place in the Qatar Open semi-finals while top seed Andrey Rublev was upset 4-6 6-4 6-3 by Jiri Lehecka.

Rublev won this tournament in 2020 and looked to be on his way to the final four after a strong opening set put him ahead.

But Lehecka battled back in the second to level the match and then found a crucial break in the second game of the deciding set to seize the advantage.

It was a lead he would not relinquish, holding his nerve despite watching a pair of match points come and go to clinch victory and knock out the world number five.

Lehecka will meet Murray in the semi-finals after the Brit came from a set down to see off Alexandre Muller 4-6 6-1 6-2 and keep his hopes of winning the Qatar Open for a third time alive after back-to-back titles in 2008 and 2009.

A tough opener had Murray facing a deficit against the world number 170, but a typically gutsy display saw him pull off the comeback and reach his first tour-level semi-final since June 2022, when he lost in the Stuttgart Open final to Matteo Berrettini.

Medvedev sealed his place in the final four with a hard-fought 6-2 4-6 7-5 win over Christopher O'Connell.

The world number eight triumphed for the seventh straight match, but did not have it all his own way against his Australian opponent, needing a crucial break with the final set tied at five games each to put himself back into the ascendancy.

Felix Auger-Aliassime awaits Medvedev in the next round after prevailing over Alejandro Davidovich Fokina in straight sets.

The world number nine out-aced his opponent eight to two to author a 6-4 7-6 (7-5) victory after one hour and 48 minutes, and he will look to improve on his dismal record against Medvedev on Friday, having lost all five of his meetings against the Russian.

At the Open 13 Provence, top seed Hubert Hurkacz reached the quarter-final after rallying from a set down to see off Leandro Riedi 4-6 6-3 6-2.

Second seed Jannik Sinner was forced to withdraw through illness, sending wildcard Frenchman Arthur Fils into the final eight, where he will meet Stan Wawrinka.

Alex De Minaur teed up a clash with Benjamin Bonzi by cruising past Alexander Ritschard 6-3 6-3, while world number 25 Grigor Dimitrov will play Alexander Bublik on Friday after beating Gijs Brouwer in straight sets.

Tennis Jamaica has announced the renewal of its partnership with National Commercial Bank Jamaica Limited (NCB) for the next staging of its highly successful Amateur Tennis series, which kicks off with the first event set for March 4 – 11, 2023.  

The series of ten tournaments will be played at the NCB Wellness and Recreational Centre in Kingston, and will see amateurs of varying levels competing in a variety of divisions namely, Men’s Class 1, 2 and 3 and Ladies A and B. 

Each tournament will also see the introduction of a Men’s Class 1A event, which will allow local professionals to showcase their skills in an exhibition round robin format while gaining invaluable match practice and experience. While the majority of events will focus on singles competition, there will also be events dedicated solely to Doubles competition as well. 

Tennis Jamaica President, John P. Azar, was elated to welcome NCB back on board for a second year.

“The NCB Amateur series was one of our many highlights of 2022. It allowed players of all levels to come out in a competitive yet friendly atmosphere. I have no doubt that the 2023 series will be even more successful as each of the last events were record-setting, with an increased number of entries each time, and there is no doubt that the players are raring to go and get back on the courts,” he said. 

Azar was quick to point out that NCB’s support had not been limited to the Amateur Series.

“Even with the best plans and ambitions, we are powerless without the support of our valued sponsors, led by NCB. They have been consistent in their support of a variety of our developmental programs and I see it as a belief in the Tennis Jamaica brand and what we are doing. I cannot thank NCB enough for their invaluable and ongoing support,” Azar added. 

Brand and Sponsorship Manager at NCB, Marion Carter, also shared her enthusiasm for the partnership, stating, “We are thrilled to be continuing our partnership with Tennis Jamaica for the 2023 Amateur Tennis Series. Supporting the development of sports in Jamaica is very important to us as we see more young Jamaicans turning to this field as a viable career and wealth-creation option for them and their families. We believe that the NCB Amateur Tennis Series is an excellent platform for players of all levels to showcase their skills and compete in an environment that is geared towards their development.” 

Azar added: “I cannot stress enough the importance of tournaments in the development of players. The presence of events such as these encourages players to practice even harder in an effort to showcase their skills. It is wonderful to see the camaraderie and fellowship between the tennis family and nothing brings that out as well as friendly but fierce competition.”

Australian Open champion Aryna Sabalenka lost for the first time in 14 matches, and Coco Gauff set up a semi-final clash with Iga Swiatek at the Dubai Tennis Championships on Thursday.

Sabalenka fought back from a set down to end the title defence of Jelena Ostapenko a day earlier, but she came up short against Barbora Krejcikova as her Czech opponent overcame a tough first set to run out a 0-6 7-6 (7-2) 6-1 victor.

Sabalenka, playing in her first event since claiming a maiden grand slam title in Melbourne, romped into the lead by breaking Krejcikova's serve three times to go a set ahead.

But the world number two was pegged back in the second as Krejcikova battled to force a tie-break, which she dominated to level the match.

Krejcikova then completed the shock victory in style, breaking the second seed twice in the final set before clinching the win on her third match point to end Sabalenka's run of 13 straight triumphs.

Karolina Muchova's withdrawal due to an abdominal injury means it is Jessica Pegula who will face Krejcikova in the semi-finals on Friday.

After Swiatek reached the final four by virtue of Karolina Pliskova pulling out because of an illness, Gauff set up a sixth meeting with the world number one by beating Madison Keys 6-2 7-5.

In those five previous clashes between the pair, Gauff is yet to win a set.

But after cruising past Keys, doing so by converting four of five break points and winning 90 per cent of her service games, Gauff is confident of improving her dismal record against Swiatek on Friday.

"All five times, I did something wrong," Gauff said. "To be honest, she's playing great tennis and there's a reason she's world number one. 

"Tomorrow I have no pressure. I just have to play my game. I definitely think I've gotten better since the last time I played her.

"Ranking is just a number at the end of the day. You just have to step on the court believing you can win, and that's what I'm going to do tomorrow."

Carlos Alcaraz finished the job against Brazilian wild card Mateus Alves to set up a second-round meeting with Fabio Fognini at the Rio Open.

Alcaraz's first-round meeting with Alves was halted on Tuesday due to heavy rain with the 2022 US Open champion leading 6-4 5-3, but the Spaniard clinched victory on Wednesday 6-4 6-4.

The top seed will take on 35-year-old Italian Fognini, who also was made to wait to secure his progress due to the Tuesday rain, eventually triumphing 6-2 6-3 over Chilean qualifier Tomas Barrios Vera.

Second seed Cameron Norrie endured a tough second-round tussle with local Thiago Monteiro, needing two hours and 30 minutes to triumph 7-5 7-5.

The Briton prevailed in one hour and 25 minutes in the first set against the 83rd-ranked Brazilian, while he was broken when serving for the match at 5-4 in the second frame.

Norrie, however, rallied to break straight back before securing victory after successfully serving the match out on the second attempt.

Fifth seed Diego Schwartzman was the major casualty of the day's play, going down 6-1 6-4 to Serbia's Dusan Lajovic in one hour and 29 minutes.

Brazilian veteran Thomaz Bellucci farewelled the ATP Tour after losing 6-3 6-2 to sixth seed Sebastian Baez.

Albert Ramos Vinolas, Bernabe Zapata Miralles and Hugo Dellien were also winners on Wednesday, with the latter progressing into the quarter-finals to face Norrie.

Andrey Rublev and Andy Murray battled to outlast their opponents at the Qatar Open, while Daniil Medvedev breezed into the quarter-finals.

Top seed Rublev, who won this tournament in 2020, responded to a first-set setback to rally to a 1-6 6-1 7-6 (8-6) win over Tallon Griekspoor on Wednesday.

The world number five was staring at a fourth opening-round defeat in five appearances this year but saved three match points en route to fighting back from 5-2 down in the decider.

Murray and fourth seed Alexander Zverev played out another three-set thriller in the Middle East, with the former world number one triumphing 7-6 (7-5) 2-6 7-5.

That clash lasted three hours and three minutes in another marathon match for Murray after defeating Italian Lorenzo Sonego in a final-set tie-break in the first round.

Medvedev (3) had no such difficulty in a comfortable 6-4 6-3 victory over world number 147 Liam Broady.

Second seed Felix Auger-Aliassime had to regain his composure during his debut in Doha, but ultimately prevailed 4-6 6-1 6-4 against Jason Kubler.

World number eight Auger-Aliassime had lost his only previous meeting with Kubler, and an upset was on the cards after the Canadian was broken in the third game and was unable to recover.

Yet he found his form with a blistering second set, reeling off five straight games to restore parity and keeping his cool in the decider.

That victory teed up a last-eight meeting with seventh seed Alejandro Davidovich Fokina, who downed Kwon Soon-woo 6-3 6-2.

Jiri Lehecka will meet favourite Rublev after beating Emil Ruusuvuori 6-2 7-6 (7-2), while Botic Van De Zandschulp was shocked by world number 170 Alexandre Muller in a straight-sets defeat.

Elsewhere at the Open 13 Provence, fifth seed Maxime Cressy fell to a surprise second-round elimination after a 6-7 (5-7) 6-4 6-3 loss to home favourite Benjamin Bonzi.

There was no such luck for the other Frenchmen in Marseille as Alexander Bublik eased past Gregoire Barrere, while Stan Wawrinka beat Richard Gasquet 4-6 7-5 6-2 to reach the last eight.

Australian Open champion Aryna Sabalenka fought back from a set down to end the title defence of Jelena Ostapenko at the Dubai Tennis Championships.

Sabalenka, playing in her first event since claiming a maiden grand slam title in Melbourne, recovered from falling behind in style to win 2-6 6-1 6-1 on Wednesday.

Ostapenko won the tournament last year and looked to be in with a chance of extending her winning streak in Dubai to seven matches.

But Sabalenka launched a strong recovery to reach the quarter-finals and extend a stunning run to start the season to 13 consecutive wins.

The second seed tightened up her game in the second and third sets and will face either Petra Kvitova or Barbora Krejcikova in the last eight.

Sabalenka had been broken three times by Ostapenko in the opening set, but she only had to fend off one break point from there.

"In the first set, she played unbelievable tennis and I couldn't do anything," Sabalenka said.

"I was looking at my team asking like, 'What can I do?', but somehow, I turned around this game and started playing really incredible tennis. 

"She plays really fast, deep balls, and I tried to stay super low, stay focused, and try to put more balls in than she did. I'm so happy that I did it."

A lower back injury for Wimbledon champion Elena Rybakina robbed supporters of what had looked like being a thrilling matchup against Coco Gauff.

The withdrawal of Rybakina meant Gauff progressed via a walkover and will face fellow American Madison Keys next.

Keys and Gauff have played twice before, winning one match apiece.

It was Gauff who won their most recent encounter in the third round of the US Open last year.

Top seed Iga Swiatek had earlier booked her place in the last eight, with the Pole's latest dominant showing in Dubai earning praise on social media from Andy Murray.

And news followed that Karolina Pliskova, her semi-final opponent, had been forced to withdraw.

Swiatek benefited from a walkover in the quarter-finals en route to winning the Qatar Open last week and is now only two wins away from another title.
