Reilly Opelka rammed 16 aces past Jenson Brooksby on the way to victory in two tie-breaks in the all-American final of the Dallas Open.

In a battle between two of the United States' brightest young men's tennis talents, neither could find a way to break the other's serve.

That meant it came down to the shoot-out of the tie-break in each set, with Opelka sealing a 7-6 (7-5) 7-6 (7-3) victory in an hour and 51 minutes.

It gives the world number 23 a third ATP title of his career, all of which have been won in America. His previous successes came at Delray Beach and the New York Open.

This indoor showpiece on Sunday was just a second main-tour final for 54th-ranked Brooksby, a player who caught the eye in a breakout 2021 campaign, and he found Opelka's serve impenetrable, as has been the case for all-comers throughout the week.

Opelka faced just one break point in the title match, the first against his serve all week, but staved that off. He had five chances against the Brooksby serve but could also not take advantage.

Rather than power, Opelka finished off the match with finesse, hitting a backhand winner after a teasing exchange. He then described 21-year-old Brooksby as "a future top-10 player" after keeping the youngster waiting for his first ATP title.

Brooksby was ranked outside the top 300 this time last year and is poised for a first top-50 breakthrough.

The champion was delighted with his own game, with Opelka saying at the trophy presentation: "I thought I played very well under pressure, especially against a great player like Jenson.

"He makes you very uncomfortable and he took me out of my comfort zone a lot of the match today. I really had to play my best tennis to get by and I barely did."

The top two seeds Casper Ruud and Diego Schwartzman will face off in the Argentina Open final after the latter won two matches on Saturday to progress at his home event.

The Argentine world number 14 had to overcome countryman Francisco Cerundolo 6-3 2-6 5-7 earlier on Saturday after their quarter-final had been interrupted by rain on Friday evening.

The match was tied at 1-1 in the third set when rain intervened, with Schwartzman triumphing when play resumed to earn a semi-final date with third seed Lorenzo Sonego.

Schwartzman would later beat Sonego 7-5 3-6 6-2 in almost three hours on a busy day for the 2020 French Open semi-finalist.

World number eight Ruud progressed with a routine 6-3 6-3 victory over Argentine sixth seed Federico Delbonis.

At the Dallas Open semi-finals, Reilly Opelka and John Isner broke the record for the longest tiebreaker on the ATP Tour since 1990.

Second seed Opelka triumphed over fellow American Isner but it was not easy, winning 7-6 (9-7) 7-6 (24-22).

Opelka sent down 39-21 aces across the match, earning a spot in the final against fourth seed Jenson Brooksby who beat Marcos Giron 6-4 6-7 (4-7) 7-6 (7-5).

Andy Murray will face the surprise package of last year's Australian Open in Saturday's final of the Sydney Classic.

Blocking Murray's way to a first ATP Tour title since October 2019 will be Russian player Aslan Karatsev, whose gritty win over Dan Evans prevented an all-British final.

Evans won a marathon tie-break in the second set of that encounter but could not maintain the level as he lost out 6-3 6-7 (13-15) 6-3 to a player who caused a sensation by reaching the 2021 Australian Open semi-finals.

It was also a case of digging deep for Murray, who picked up a stellar win over American Reilly Opelka, triumphing 6-7 (6-8) 6-4 6-4 against the fourth seed and world number 25. Murray is ranked down at number 135, but this strong week has provided evidence he still belongs at a much higher level.

Three years have passed since Murray came to Australia and indicated he was close to retirement due to hip trouble. He has battled back against the odds to stay active, but his lone ATP singles final appearance since that point came at the 2019 European Open in Antwerp, where he beat Stan Wawrinka to land a surprise title.

Now he is back in another title match, for what will be just his fourth singles final on the main tour since the end of the 2016 season, when he reached world number one status.

Murray rifled 16 aces and no double faults, winning an impressive 88 per cent of points when he landed his first ball in court, and his serve was not broken at any point by Opelka.

He has 46 singles titles and dearly wants to reach 50 before calling it a day, with a glorious chance to land a 47th coming up on Saturday.

Karatsev, the world number 20, is not a player that Murray would underestimate. He was ranked 114th and largely unknown before going on his run to the final four in Melbourne last February, but he has since pushed on and should provide a stiff test for three-time major winner Murray.

"It's already been a great week for me, big progress from anything I've done in the last year or so, to string four matches together like this and against top players in Basilashvili and Opelka," said Murray. "I'll go for 47 tomorrow. It's been a good week, I've played better with each match, so hopefully I'll step it up again."

At the Adelaide International 2 event, Australian wildcard Thanasi Kokkinakis produced a stunning semi-final win over fourth seed Marin Cilic, battling to a 6-2 3-6 7-6 (12-10) victory over the former US Open champion, teeing up a shot at Frenchman Arthur Rinderknech in the title match.

Andy Murray powered through to his first ATP Tour final since October 2019 after a stellar win over Reilly Opelka at the Sydney Classic.

Murray won 6-7 (6-8) 6-4 6-4 against his American opponent, with fourth seed and world number 25 Opelka undone by the British wildcard.

Three years have passed since Murray came to Australia and indicated he was close to retirement due to hip trouble.

There have been highs and lows since then as the three-time grand slam winner has fought to resuscitate his career. His lone ATP final appearance since that point came at the 2019 European Open in Antwerp, where he beat Stan Wawrinka to land a surprise title.

Now he is back in another title match, for what will be just his fourth final on the main tour since the end of the 2016 season, when he reached world number one status.

Opelka is renowned as a big server and duly sent down 20 aces and four double faults, but Murray showed he can compete on that front too with 16 aces and no doubles.

The Scot also won an impressive 88 per cent of points when he landed his first ball in court, and his serve was not broken at any point.

Murray was awaiting the winner of the second semi-final between his fellow Briton Dan Evans and Russian Aslan Karatsev.

Five-time Australian Open runner-up Murray has been drawn to face Georgian Nikoloz Basilashvili in the first round of the grand slam at Melbourne Park next week. He beat 23rd-ranked Basilashvili in round two in Sydney.

Andy Murray strode through to the semi-finals at the Sydney Classic after opponent David Goffin was forced to retire with an injury.

Murray won the opening set 6-2 before eighth seed Goffin, who had been receiving treatment on his knee, determined he could no longer continue.

It is the first time the 34-year-old Murray has reached a semi-final on the ATP Tour since winning the European Open title in October 2019.

Though not ideal circumstances, Murray will at least be glad of the extra rest after his three-hour encounter with world number 23 Nikoloz Basilashvili in the second round. The Scot has also been drawn to play Basilashvili in the first round of the Australian Open.

Murray will face Reilly Opelka in the last four in Sydney after the American beat compatriot Brandon Nakashima 7-6 (7-4) 6-2 to advance.

Top seed Aslan Karatsev was made to work for his win against Italy's Lorenzo Sonego but secured a 6-3 3-6 6-2 victory to book his semi-final place against Briton Dan Evans, who defeated American Maxime Cressy 6-4 7-6 (7-5). Cressy reached the final of the Melbourne Summer Set tournament last week.

At the Adelaide International 2 event, third seed Karen Khachanov tumbled out after losing in straight sets to Arthur Rinderknech, the Frenchman coming through a 7-6 (9-7) 7-5 winner.

Rinderknech will face compatriot Corentin Moutet in the semi-finals after the qualifier overcame Thiago Monteiro 6-4 6-4.

Fourth seed Marin Cilic battled to beat American Tommy Paul 6-4 2-6 6-3, and a test awaits against Thanasi Kokkinakis who defeated fellow Australian Aleksandar Vukic 6-7 (5-7) 6-3 6-2.

Jannik Sinner continued his push for an ATP Finals spot with a straight-sets defeat of Reilly Opelka in the first round of the Vienna Open, while Carlos Alcaraz exacted revenge on Andy Murray.

Sinner won his fourth title of what has been an outstanding season for the Italian in Antwerp last weekend and is only 110 points adrift of Hubert Hurkacz in the battle for the final place in the season-ending event in Turin.

Murray did the 20-year-old a favour by knocking Hurkacz out of the ATP 500 tournament in the Austrian capital on Monday and seventh seed Sinner eased to a 6-4 6-2 win over American Opelka two days later.

Sinner, who will overtake Pole Hurkacz if he reaches the semi-finals this week, won 93 per cent of points behind his first serve and did not face a break point in a resounding win and will play Dennis Novak in the second round.

Murray beat Alcaraz at Indian Wells this month, but the 18-year-old rising star from Spain turned the tables on the three-time grand slam champion with a 6-3 6-4 second-round win in Vienna.

Former world number one Murray struggled with his serve and was broken five times as he made an early exit.

Third seed Matteo Berrettini beat Nikoloz Basilashvili 6-7 (5-7) 6-2 6-3 to reach the third round, while Diego Schwartzman, Gael Monfils and Lorenzo Sonego moved into the second round.

In the St Petersburg Open, defending champion Andrey Rublev beat Ilya Ivashka 6-4 6-4 to reach the quarter-finals along with Denis Shapovalov, a 2-6 6-3 6-0 winner against Pablo Andujar.

Jan-Lennard Struff also moved into the last eight, with Karen Khachanov and Marin Cilic securing first-round wins.

Top-10 seeds Andrey Rublev and Denis Shapovalov were bounced from the Indian Wells Masters on Monday as number one seed Daniil Medvedev hit a season milestone. 

Tommy Paul took down Rublev, beating the fourth seed for the first time in four meetings, while the ninth-seeded Shapovalov fell to Aslan Karatsev.

The news was not all bad for the higher seeds, though, as US Open champion Medvedev picked up his 50th win of the year. 

PAUL DOWNS RUBLEV

Playing in the main draw at Indian Wells for the first time, the 24-year-old American Paul outlasted Rublev 6-4 3-6 7-5 for his second win in eight career matches against top-10 players.

Paul was on the offensive throughout the match, firing 41 winners while making 37 unforced errors, while Rublev had 23 of each. 

The Russian will lament missed opportunities, as he converted just four of 14 break point chances before watching Paul break him twice in the final set to prevail. 

Paul moves on to face 21st seed Cameron Norrie, who beat Roberto Bautista Agut 6-4 5-7 6-3.

MEDVEDEV NOTCHES 50TH WIN

Medvedev had to work a bit to get past 27th seed Filip Krajinovic 6-2 7-6 (7-1), improving to 38-5 on hard courts in 2021. Only Stefanos Tsitsipas (52) has more victories overall this year. 

The Russian had 25 winners and 18 unforced errors while winning 70 per cent of points on his first serve. 

He next faces 23rd seed Grigor Dimitrov, who downed 16th seed Reilly Opelka 6-3 6-4. 

KARATSEV UPSETS SHAPOVALOV

Playing at Indian Wells for the first time, 19th seed Karatsev upset Shapovalov 7-5 6-2, saving the only break point he faced in the match.

Casper Ruud, seeded sixth, rallied past Lloyd Harris 6-7 (4-7) 6-4 6-4 as he seeks his sixth tournament title this year. 

He will face 11th seed Diego Schwartzmann, who beat 18th seed Daniel Evans 5-7 6-4 6-0 to reach the fourth round at Indian Wells for the first time.

Eighth seed Hubert Hurkacz had little trouble with Frances Tiafoe, rolling past the American in straight sets.

Jannik Sinner, the 10th seed, advanced via walkover when John Isner withdrew from the tournament to fly home and be with his wife Madison with their third child expected to arrive ahead of schedule on Tuesday. 

Team Europe are on track for their fourth consecutive Laver Cup triumph after earning an early 3-1 lead against Team World.

Opening-day honours went to Bjorn Borg's Team Europe at TD Garden in Boston, where the defending champions moved into the box seat thanks to wins for Andrey Rublev, Matteo Berrettini and Casper Ruud in the singles on Friday.

John Isner and Denis Shapovalov managed to get Team World on the board in the evening's final doubles match against Alexander Zverev and Berrettini 4-6 7-6 (7-2) 10-1.

Roger Federer and Rod Laver were in the crowd as Team Europe – headlined by newly crowned US Open champion Daniil Medvedev and consisting of six of the world's top 10 – made a strong start courtesy of Norwegian Ruud, who overcame Reilly Opelka 6-3 7-6 (7-4), improving his career record to 3-0 against the towering American, and beating him in straight sets for the first time.

Italian star Berrettini then overcame Team World's Felix Auger-Aliassime 6-7 (3-7) 7-5 10-8 in the competition's longest match at two hours, 52 minutes.

Berrettini escaped with the second set after facing two break points in the penultimate game before prevailing against the Canadian in a thrilling match tie-break.

"One of the best matches bar none that I've ever seen played, absolutely just enthralling," said captain John McEnroe, whose Team World are eyeing their first Laver Cup trophy.

Rublev rallied past Argentina's Diego Schwartzman, who won the opening set and led 6-2 and 8-5 in the match tie-break before losing 4-6 6-3 11-9.

"Today we are a bit more lucky; Matteo won a tough match against Felix in a super tiebreak, now you saw my match," said Russian star Rublev.

"It was so close; Diego was leading all the super tiebreak, but in the end I find a way to win.

"This happens. This is tennis, this is sport. It’s emotions. Someone has to win, someone has to lose."

On day two, Stefanos Tsitsipas and Zverev headline the day session against Team World's Nick Kyrgios and Isner.

In the evening, Medvedev will meet Shapovalov before Rublev and Tsitsipas team up for a doubles battle with Kyrgios and Isner.

Nick Kyrgios, John Isner and Reilly Opelka have been named by Team World captain John McEnroe as his final three picks for the Laver Cup.

The trio join Denis Shapovalov, Felix Auger-Aliassime and Diego Schwartzman for the team event which runs from September 24-26 at TD Garden in Boston.

Laver Cup newcomer Opelka rose to a career-high world number 23 ranking en route to his first ATP Masters 1000 final in Toronto and defeated world number three Stefanos Tsitsipas, who will play for Bjorn Borg's Team Europe.

Isner, who has featured for Team World since the inaugural event in 2017, reached the semi-finals in Toronto and claimed his 16th ATP Tour title in Atlanta at the start of August.

He described the Laver Cup as "a highlight of my year", adding: "To be on a team with guys we're normally competing against is so different and so much fun. We come together so well as a group, the chemistry is awesome and it's such a great environment to be part of."

Australian firebrand Kyrgios is a striking inclusion in Team World's roster, while Team Europe will be without their big three: Roger Federer, Rafael Nadal and Novak Djokovic.

Federer and Dominic Thiem were expected to take part in this year's event, though both were forced to withdraw with injuries.

However, Borg's men still boast six of the world's top 11. World number two Daniil Medvedev leads the line-up, with Tsitsipas and Tokyo Olympics gold medallist Alexander Zverev for company.

Casper Ruud, who collected a 14th win in his last 15 completed matches on tour when he beat Opelka on Wednesday, will feature, while Andrey Rublev and Wimbledon finalist Matteo Berrettini complete the six-man team.

Team Europe have landed the title in each of the three editions of the tournament so far, with Prague, Chicago and Geneva having served as hosts.

Daniil Medvedev lived up to his top-seed billing by overcoming Reilly Opelka in straight sets in the National Bank Open final.

World number two Medvedev prevailed 6-4 6-3 in Toronto on Sunday as he became the first Russian to win the ATP tournament since Marat Safin in 2000.

Medvedev now holds four of the nine ATP Masters 1000 titles, having also previously come out on top in Cincinnati, Shanghai and Paris.

He saved all four break points faced against unseeded Opelka, who stunned Stefanos Tsitsipas in the semi-finals, and needed just 85 minutes to complete the job.

Reflecting on his latest tour triumph, Medvedev said: "I could not have dreamt of this at one point.

"With Novak [Djokovic] and Rafael [Nadal] playing, it seemed like an untouchable achievement. Now I have four wins in five finals, which is a good score. I am just happy. 

"Playing Canada and Cincinnati, the goal is to win as many matches as possible. I was able to do it two years ago and I will try and do it again."

Opelka was competing in his maiden final at this level and started strongly, racing 40-0 ahead in the fourth game with some powerful hitting.

However, the 23-year-old – the first American to reach the final since Mardy Fish in 2011 – could not break his opponent as Medvedev recovered with some impressive serving to take the game.

Medvedev earned the first break in the following game and comfortably held to take the first set.

The Russian forced Opelka into errors in the second set and reeled off nine points in a row en route to breaking his opponent in the third game.

It was plain sailing from that point on as two-time beaten grand slam finalist Medvedev eased over the line to add another trophy to his collection.

Top seed Daniil Medvedev will face Reilly Opelka in the National Bank Open final after the American stunned Stefanos Tsitsipas in a three-set classic in Saturday's semi-finals.

World number 32 Opelka fought back from a set down in Toronto to knock out favoured third seed Tsitsipas in two hours and 32 minutes.

The 23-year-old American triumphed 6-7 (2-7) 7-6 (7-4) 6-4, booking a spot in his first ATP Masters 1000 final.

Opelka sent down 17 aces but also hit 27 groundstroke winners in the shock victory over 2021 Australian Open semi-finalist Tsitsipas who had beaten in-form Casper Ruud in the quarters.

"I played great," Opelka said in his on-court interview. “These courts suit my game, it is no coincidence that John Isner is in the other semi-final.

"Stefanos has definitely improved his returning. Come 5-5 in the first set, a lot of balls started to come back. He is a thinker and has a high tennis IQ, so it was expected, but that is what separates him from the rest of the pack."

Opelka was aided by an excellent first serve percentage of 72 per cent, winning 62 of 81 points when he made his first serve.

Both first two sets went to tiebreaks, with Tsitsipas failing to generate a break point until the third set. Opelka made the first break of the match in the seventh game of the third set and held serve twice after to seal victory.

World number two Medvedev cruised into the decider with a commanding win over John Isner in less than an hour.

Medvedev, who was runner-up in Toronto in 2019, won 6-2 6-2 over the big-serving American, with the match totaling 54 minutes.

Isner could only manage four trademark aces for the match, while the Russian had 11 and broke the American four times from seven opportunities.

This time, Rafael Nadal could not summon the third-set magic he needed.

Coming off an epic three-hour duel Wednesday in his first match since the French Open final, Nadal fell to Lloyd Harris 6-4 1-6 6-4 on Thursday at the Citi Open. 

After a short-lived maiden appearance at the Washington, D.C. tournament, the Spaniard will look ahead to Toronto and Cincinnati as he continues his preparations for the U.S. Open. 

Harris, meanwhile, heads to a quarter-final matchup against veteran Kei Nishikori after recording the biggest win of his career. 

Facing Nadal for the first time, the 24-year-old South African slammed 16 aces Thursday and saved four of six break points. 

The 20-time grand slam winner, who battled a foot injury to outlast Jack Sock in his first match, did not have enough to answer the world number 50 on Thursday.

In addition to the top-seeded Nadal's defeat, second seed Felix Auger-Aliassime also went down Thursday, falling 6-3 6-4 to American wild card Jenson Brooksby. 

With their exits, the tournament is now without its top four seeds. 

That leaves fifth seed Jannik Sinner as the top player remaining after he defeated Sebastian Korda 7-6 (7-3) 7-6 (7-3). 

Nishikori advanced by downing seventh seed Cameron Norrie 3-6 6-3 6-3, while John Millman knocked out eighth seed Reilly Opelka 6-3 7-6 (7-4). 

Among unseeded players, Denis Kudla defeated the red-hot Brandon Nakashima 3-6 7-6 (7-3) 6-4, while Steve Johnston eased past Ricardas Berankis 6-2 6-1 and Mackenzie McDonald beat Illya Ivashka 6-4 6-4. 

In addition to Harris-Nishikori, Kudla will face McDonald in the other quarter-final in the top half of the draw, while Sinner meets Johnson and Millman takes on Brooksby in the bottom half. 

Fifth seed Taylor Fritz defeated compatriot fourth seed Reilly Opelka in a three-set epic in the quarter-finals at the Atlanta Open on Friday.

Fritz, who reached last week's Los Cabos Open semi-finals and is currently ranked 36th in the world, edged out Opelka 7-6 (7-5) 6-7 (3-7) 7-6 (7-4) in just under three hours.

The pair sent down a combined 48 aces, with Fritz claiming 25 of them, with all sets going to tiebreakers, with no breaks of serve.

Third seed Cameron Norrie was bundled out by Finnish world number 78 Emil Ruusuvuori in straight sets.

Norrie, who won last week's Los Cabos Open for his maiden ATP Tour title, was beaten 7-6 (7-1) 6-3 by the Finn.

Ruusuvuori will take on teenager Brandon Nakashima in the semi-finals, after the American – who was runner-up to Norrie in Los Cabos - beat Jordan Thompson 7-6 (7-5) 7-5.

Sixth seed John Isner sent down 30 aces as he got past Australian qualifier Chris O'Connell 7-6 (7-5) 6-7 (3-7) 6-4.

Top seed Milos Raonic saw his stay at the Atlanta Open come to an early end with a three-set defeat to American Brandon Nakashima on Wednesday. 

The 19-year-old Californian Nakashima, ranked 115th in the world, prevailed 5-7 6-3 7-6 (7-4) over world number 22 Raonic in their first meeting. 

The big-serving Canadian had 10 double faults to go with his 27 aces, while Nakashima did not commit one double fault and managed 13 aces. 

It was the latest in a string of recent wins over established players for Nakashima, who stunned Sam Querrey and John Isner last week at Los Cabos before falling to Cameron Norrie in the final. 

Nakashima next faces Australia's Jordan Thompson, who beat Peter Gojowczyk of Germany 7-6 (8-6) 6-4 to reach the quarter-finals. 

In the other half of the draw, fifth seed Taylor Fritz rallied to defeat fellow American Steve Johnson 6-7 (5-7) 6-4 6-1 in a rematch of a quarter-final at Los Cabos, also won by Fritz. 

Fritz will face countryman Reilly Opelka, who outlasted Bjorn Fratangelo 7-6 (7-3) 7-6 (7-4). The 6-foot-11 Opelka pounded 25 aces to just three double faults, winning 84 per cent of his service points. 

Novak Djokovic dug deep in the face of fierce Roman resistance to set up a showdown with Rafael Nadal in the men's final at the Internazionali d'Italia.

World number one Djokovic came from a set down overnight to beat Stefanos Tsitsipas 4-6 7-5 7-5 early on Saturday, before returning to the court to face Italian Lorenzo Sonego in the evening.

The Rome crowd raucously rallied behind Sonego, who beat Andrey Rublev earlier in the day, and the 26-year-old rose to the challenge but eventually fell to a 6-3 6-7 (5-7) 6-2 defeat.

Djokovic had match points before serving for it at 6-5 in the second set, yet it was to prove a stirring game as the noisy home crowd encouraged Sonego, who snatched a gutsy break. The tie-break looked set to be wholly one-sided when Djokovic raced 3-0 ahead, but it was soon back on serve, partisan spectators at the Foro Italico roaring in delight at a double fault from the Serbian.

From 4-2 behind, Sonego surged to 6-4 ahead in the tie-break. He failed to convert a first set point when ripping a forehand into the net, but the set was his when Djokovic sent a backhand service return long.

Sonego then had 0-40 against the Djokovic serve at the start of the decider, but he could not force the break, and the top seed gained strength from that escape, eventually cruising to victory.

Five-time Rome champion Djokovic said on Amazon Prime: "I bounced back very well after the second set. Maybe if he started with a break up in the third, things would look differently. I also had my chances and I only had myself to blame for not closing the match in straight sets.

"But he's a quality player, very dynamic, it's not easy to play against him and obviously he had the crowd behind him. It was an electric atmosphere. In the end I managed to close out the match really well."

Looking ahead to tackling Nadal, Djokovic said: "I need to recover. Hopefully I'll have fresh legs because that's what I definitely will need and it's necessary to have a chance against Rafa. He also had some tough matches [this week] and hopefully I'll be fresh and I'll give it all."

While Djokovic and Sonego thrashed away into the night, nine-time champion Nadal had no such workload issues on Saturday.

Nadal beat Alexander Zverev on Friday to set up a semi-final against American Reilly Opelka, and the Spaniard snatched a 6-4 6-4 win from that contest to reach the title match.
