Jenson Brooksby made a winning start to his 2022 season on the ATP Tour as he reached the quarter-finals of the Dallas Open.

Last year's ATP Newcomer of the Year missed the Australian swing after testing positive for COVID-19 and only made his return at the Columbus Challenger at the end of last month.

The world number 54 admitted to feeling a little nervous in his 6-3 3-6 6-3 win over Andreas Seppi, but he said: "I competed well. As an American in the U.S., it was a great crowd. I missed that atmosphere for a few months.

"I thought I stayed pretty calm out there; a good balance of calm and competing, which is always a focus of mine."

Fifth seed Adrian Mannarino enjoyed smoother progress into the quarter-finals, beating Yoshihito Nishioka 6-3 6-1.

Vasek Pospisil saved a match point before coming through 6-7 (3-7) 7-6 (8-6) 6-2 against Jurij Rodionov, setting up a last-eight clash with home favourite John Isner, whose compatriot Reilly Opelka also progressed from a big-serving contest with Cedrik-Marcel Stebe.

At the Argentina Open, Fabio Fognini progressed to his first Tour-level quarter-final since April after battling past Pedro Martinez.

The Italian won 6-4 7-6 (7-5) to secure a meeting with Federico Delbonis, the Argentine having dispatched Pablo Andujar in straight sets.

Delbonis' compatriot Diego Schwartzman also defeated Spanish opposition in the form of Jaume Munar, although the world number 15 was made to work hard for a victory that sent him into a last-eight contest with Francisco Cerundolo.

Schwartzman came through 7-6 (7-2) 7-6 (7-4) in two hours and 23 minutes, eventually closing out the victory with a return winner on his seventh match point.

"I'm very happy because it was tough at the end," Schwartzman said. "He was saving too many match points, winning too many good points at the end of the match and he had the chance to go into the third.

"I think the tie-break, in the beginning, I played better than him. But at the end, he was fighting and he was there."

Albert Ramos Vinolas has fought back from a set down and a final-set double break down to win the Cordoba Open over Chilean qualifier Alejandro Tabilo on Sunday.

Spanish Sixth seed Ramos Vinolas won 4-6 6-3 6-4 in two hours and 40 minutes to claim his fourth career title.

The 34-year-old, who is ranked 44th in the world, trailed 4-1 in the third set, down two breaks but rallied back to win the next five games to clinch victory.

Tabilo had knocked out top seed Diego Schwartzman in the semi-finals and looked on course for victory after winning the first set when he sent down five aces.

The Chilean got a break ahead in both the second and third sets but could not hold his composure under pressure.

Ramos Vinolas was excellent on his return in the third set converting three of four break points, with the tiring Tabilo failing to have any aces in the deciding set.

The Spaniard, whose last title was in Estoril in 2021, improves to 4-7 in Finals at the ATP Level.

Top seed Diego Schwartzman cruised into the quarter-finals of the Cordoba Open after a straight-sets win over countryman Juan Pablo Ficovich on Wednesday.

World number 14 Schwartzman triumphed 6-3 6-2, converting three of five break points to win in one hour and 10 minutes.

Schwartzman will face Colombian lucky loser Daniel Elahi Galan who progressed with a 6-2 3-6 6-1 victory over Jaume Munar.

Eighth seed Pedro Martinez was eliminated by Argentina wildcard Juan Ignacio Londero 6-3 7-6 (7-3).

Londero will face Serbian Nikola Milojevic, another lucky loser, who got past wild card Tomas Martin Etcheverry 6-3 7-6 (7-4).

Diego Schwartzman sealed a 2-0 win for Argentina over Greece in Group D of the ATP Cup after edging a close contest with world number four Stefanos Tsitsipas.

Schwartzman claimed just the third victory of his career over a top-five opponent, winning 6-7 (5-7) 6-3 6-3 in Sydney.

The world number 13 fought back from a break down in the second set before taking his career head-to-head with Tsitsipas to 2-1 after battling through two hours and 42 minutes on Ken Rosewall Arena.

"I was just trying to think that it was his first match for two months after his elbow [injury], so I was thinking just to try and be in the match," Schwartzman said in his on-court interview.

"I had the chance and I think I was ready. I am very happy because playing against Stefanos and being a set and a break down is not easy, but I found a way."

Argentina, who earlier saw Federico Delbonis defeat Michail Pervolarakis in straight sets, will now face Poland on Wednesday to decide who progresses to the semi-finals.

Poland were comfortable 3-0 winners in their match-up with Georgia, Kamil Majchrzak beating Aleksandre Bakshi for the loss of just two games before Hubert Hurkacz defeated Aleksandre Metreveli 6-7 (5-7) 6-3 6-1.

Pablo Carreno Busta beat Viktor Durasovic 6-3 6-3 to put Spain ahead against Norway, and their win was assured when Roberto Bautista Agut claimed an impressive 6-4 7-6 (7-4) victory over Casper Ruud. Alejandro Davidovich Fokina and Pedro Martinez followed up with a straight-sets doubles win.

"Casper is playing unbelievable tennis, [he did] an unbelievable performance last year, and today I played very good," Bautista Agut said. "I returned very well, I made very few unforced errors and I played aggressively. I try to play matches like this and that is why I am practising hard and I am trying to show this level."

Spain are top of Group A ahead of Serbia, whose match with Chile will go down to a doubles decider.

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.

Jannik Sinner said he was "very proud" of the level he played at as he stormed to a straight-sets victory against Diego Schwartzman in the final of the ATP European Open on Sunday.

The number one seed continued his impressive form in the tournament by sweeping aside his opponent 6-2 6-2 in just 76 minutes.

Sinner was too powerful for his Argentine opponent and showed just why he is considered to be one of the rising stars of tennis with some breathtaking winners from all over the court in Antwerp, Belgium.

"I felt great on court. I moved well. I also served better, I think," the 20-year old said. "I felt great, but in tennis every day is different. You have to be careful. I think I played well the whole tournament, to be honest, from the first point to the last point.

"I like to play indoors. I tried to push the ball [through the court], which for me was important against Diego because he is moving very well. He's not missing so many shots. For me it was important trying to adapt the game somehow against him.

"I think I can be very proud about the level I played."

The top two seeds will do battle in the European Open final following commanding victories for Jannik Sinner and Diego Schwartzman on Saturday.

Sinner, the number one seed, moved into his fifth final of the season with a 6-2 6-2 defeat of Lloyd Harris in Antwerp.

The 20-year-old Italian, who is in the hunt for a maiden ATP Finals spot, dominated Harris from the baseline and saved all three break points he faced.

There were only 16 unforced errors from the racket of the composed Sinner, who will be bidding to win his fourth title of the season on Sunday.

Sinner said: "I am very happy to be in the final. I just love playing here and love playing indoors, so hopefully I can play a great match again tomorrow."

Schwartzman ended 20-year-old American Jenson Brooksby's impressive run with a 6-4 6-0 victory.

The Argentinian struck 15 winners and secured five breaks as he marched into the championship match.

Russian second seed Aslan Karatsev will come up against Marin Cilic in his first final on home soil after knocking compatriot Karen Khachanov out of the Kremlin Cup.

Karatsev beat Khachanov 7-6 (9-7) 6-1, while sixth seed Cilic – a two-time winner of the tournament in Moscow – got the better of Ricardas Berankis 6-3 6-4.

Jenson Brooksby enhanced his growing reputation and set up showdown with Diego Schwartzman in the European Open semi-finals.

The 20-year-old American, who took a set off Novak Djokovic and rattled the world number one at the US Open, is shaping up as potentially his country's biggest hope for the future in the men's game.

Californian Brooksby crushed Spain's world number 44 Alejandro Davidovich Fokina 7-5 6-0, and second seed Schwartzman awaits after the Argentinian took down another 20-year-old American, Brandon Nakashima, scoring a 6-4 6-2 quarter-final win.

Schwartzman is the man who ended Andy Murray's hopes at the tournament in Antwerp.

Brooksby, who had to win two qualifying matches to reach the main draw, said: "Tomorrow will be a great match. I'm really looking forward to it. I'll get some rest tonight and get ready to battle again tomorrow."

The other semi-final will see Italian top seed Jannik Sinner take on South African seventh seed Lloyd Harris following their respective straight-sets wins over Arthur Rinderknech and Marton Fucsovics.

There will be an all-Russian semi-final at the Kremlin Cup in Moscow, after Aslan Karatsev and Karen Khachanov won through to the final four.

Second seed Karatsev sank the hopes of Frenchman Gilles Simon, breaking serve five times on the way to a 6-4 6-3 win, while third-seeded Khachanov edged out Australian John Millman. A 7-5 7-6 (7-4) grind featured 19 aces by Khachanov, the 2018 Kremlin Cup champion, who saved four set points in the second set.

Marin Cilic thrashed Pedro Martinez 6-1 6-2 to set up a tussle with Ricardas Berankis, the Lithuanian ending Adrian Mannarino's run with a 6-2 7-6 (7-1) success. Frenchman Mannarino had stunned Russian top seed Andrey Rublev in the previous round.

Andy Murray fumed at his own mentality and "poor" attitude after falling to a straight-sets defeat to Diego Schwartzman at the European Open.

Two days on from beating Frances Tiafoe in a three-set epic, Murray fell to a 6-4 7-6 (8-6) loss to the second-seeded Argentine in Antwerp.

The three-time grand slam winner, who in January 2019 underwent hip resurfacing surgery, was 4-1 up in the first set but was reeled back in and lost out in a hard-fought contest.

Following the defeat, a frustrated Murray said: "I didn't make as many good decisions as I would have liked in the second set dealing with adversity.

"Mentally I was poor, and my attitude was poor on the court."

Murray is still slated to play in Austria and Stockholm before the season is out, while he could also enter the Paris Masters either via a wildcard entry or going through the qualifiers.

"There'll be a decision on the final Paris wildcard on Monday, but I might even play the qualis there," Murray added. 

"Sport is a results business. Play well or poorly doesn't really matter if you lose matches. You need to be winning. 

"That's what I want in the last few tournaments. They are really strong tournaments and there are no guarantees the results will come, but I want to win more matches."

Andrey Rublev's hopes of retaining the Kremlin Cup on home soil in Moscow are over after he suffered a surprise defeat to Adrian Mannarino.

Mannarino ultimately came out on top 5-7 7-6 (7-4) 6-3 but he had to do it the hard way, coming back from match point down to set up a meeting with Ricardas Berankis, who lost only tree games in a 6-2 6-1 win over Federico Coria.

Rublev was never cruising, however, as Mannarino only just fell short in the first set and then took the second to a tiebreak, which he eventually won to turn the tide.

The 33-year-old, who lost to Rublev in the final two years ago, took things up a notch in the decider and did not face a single break point as he got the job done despite the home support.

"The crowd was cheering for Andrey but that is normal," he said after reaching the quarter-finals. "I was happy to play with such a nice atmosphere.

"We have been playing for a long time without fans, so it is nice to enjoy a stadium with crowds now."

Second-seed Aslan Karatsev is now the favourite in Moscow, and the Russian had few issues in a 6-4 6-3 defeat of Egor Gerasimov.

Karatsev will face Gilles Simon next following his 6-3 6-2 win over Mackenzie McDonald, while Pedro Martinez won 6-3 6-4 over Filip Krajinovic to book his passage.

At the European Open in Antwerp, Andy Murray's hopes of winning a first ATP Tour title in two years were ended by number two seed Diego Schwartzman.

The Argentinian trailed 4-1 in the first set but fought back to win 6-4 7-6 (8-6) in his first ever match against the Scot, whose last tour triumph was in Antwerp.

In his on-court interview, Schwartzman said: "It was a pleasure to play against Andy. We had not played before and he is coming back and every week he is playing better and moving better.

"I have a lot of respect because when I grew up playing tennis, I was watching Roger [Federer], Rafa [Nadal], Andy and Novak [Djokovic] and right now playing against him is a pleasure for me."

Seventh seed Lloyd Harris is also into the quarter-finals after a straightforward 6-2 6-3 victory over Jan-Lennard Struff in just 72 minutes, Marton Fucsovics came through 6-7 (5-7) 6-3 6-1 against Roberto Bautista Agut and Brandon Nakashima edged past Henri Laaksonen 7-6 (7-5) 6-7 (5-7) 6-3 to earn the right to face Schwartzman.

Grigor Dimitrov continued his red-hot form with a hard-fought victory over Hubert Hurkacz at the Indian Wells Masters, where Cameron Norrie awaits in the semi-finals.

After conquering top seed Daniil Medvedev, former world number three Dimitrov recovered from a set down to upstage eighth seed Hurkacz on Thursday.

Norrie shocked 11th seed Diego Schwartzman in straight sets at the ATP 1000 tournament.

DIMITROV CELEBRATES MILESTONE

Bulgarian star and 23rd seed Dimitrov reached his first ATP Masters 1000 semi-final of the season with a 3-6 6-4 7-6 (7-2).

Dimitrov showed he is the comeback king once again, having also saved two break points at 3-3 in the second set.

A semi-finalist at the US Open (2019), Australian Open (2017) and Wimbledon (2014), Dimitrov then squandered a 5-2 lead in the deciding set before eventually prevailing in a tie-break for his 100th Masters 1000 victory.

NORRIE BOOSTS TURIN BID

Norrie's hopes of qualifying for the ATP Finals in Turin received a boost after breezing past Schwartzman 6-0 6-2.

Amid a career-best season, Norrie advanced to his maiden ATP Masters 1000 semi-final, with the 26-year-old to replace Daniel Evans as the new British men's number one.

Seeded 21st, Norrie – who has 45 Tour-level wins in 2021 – now has next month's Finals firmly in sight, having started the day 945 points behind ninth-placed Hurkacz in the race to Turin.

"I have been pretty consistent this year," Norrie said after 74 minutes on court. "I think I am really doing the fundamentals well on serve and return and playing the big points better.

"I have been a little more aggressive and feel I am learning more as I go along and becoming more experienced. We are really happy."

Daniil Medvedev was ousted from the Indian Wells Masters, the US Open champion and top seed stunned by former world number three Grigor Dimitrov in a thrilling comeback.

Dimitrov had been a set and a double break down against the Russian star on Wednesday, before launching a remarkable rally for his first win over a top-two opponent since 2016.

Meanwhile, second seed Stefanos Tsitsipas and third seed Alexander Zverev both won to secure their spots in the last eight.

MEDVEDEV SHOCKED IN THE DESERT

Dimitrov roared back to triumph 4-6 6-4 6-3 over Medvedev, who had won 18 of his past 19 matches on North American soil.

Bulgarian star Dimitrov trailed 4-1 in the second set after dropping the opener before stunning the first-time grand slam champion midweek.

"I just felt something at 1-4 and I calmed myself down and started to take better decisions and started to control the pace of the game, which I really believed helped me," Dimitrov – the 23rd seed – said. "In the end it was just very solid and smart play."

Dimitrov finished the match with 25 winners, while he was also excellent at the net, helping him claim his first quarter-final appearance at an ATP Masters 1000 event this season.

Medvedev sent down 5-1 aces but only managed a 54 per cent first-serve percentage, while he also faced 10 break points across the match. Dimitrov won five games in a row to claim the second set.

"I don't remember myself losing three service games, even four service games ever, I guess, on hard courts," Medvedev said.

"That shows how slow this court is and the conditions, more like clay, I would say, which I don't like, because to lose serve four times is just unacceptable."

Dimitrov will face eighth seed Hubert Hurkacz in the quarter-finals after he got past Australian Open semi-finalist Aslan Karatsev 6-1 6-3.

Medvedev added: "Grigor played [the] second part of the match better than anybody did against me [at the] US Open that I won. Playing this level, I don't see him losing to anybody, but let's see the result."

ZVEREV MAKES STATEMENT WITH MONFILS WIN

Olympic Games gold medallist Zverev bulldozed his way past 14th seed Gael Monfils 6-1-6-3 en route to the last eight.

German star Zverev claimed his 20th win from his last 21 matches, needing just over an hour to dispatch Monfils.

Zverev claimed 19 of 25 points at the net, hitting 19 winners including 11 with his forehand, while converting four of eight break points.

"I felt well on the court today. Gael is someone I haven't beaten before, so I knew had to play my best tennis and I definitely was not far away," Zverev said during his on-court interview.

Zverev will take on American 31st seed Taylor Fritz, who defeated 10th seed Jannik Sinner 6-4 6-3.

TSITSIPAS OUTLASTS DE MINAUR

French Open runner-up Tsitsipas saw off a tough challenge from Australian Alex de Minaur to secure his spot in the quarter-finals 6-7 (3-7) 7-6 (7-3) 6-2.

Tsitsipas fought back from a set down to win against the 22nd seed, triumphing in two hours, 43 minutes.

Greek star Tsitsipas showed grit to outlast the tiring De Minaur and will face 29th seed Nikoloz Basilashvili after he knocked off fellow seed Karen Khachanov 6-4 7-6 (8-6).

"That was incredible the way I just stayed in the match," Tsitsipas said. "I had to go through so many difficulties in order to find a solution and I executed towards the end of the match."

There were further top-10 casualties, with sixth seed Casper Ruud also bowing out 6-3 6-3 to 11th seed Diego Schwartzman, who will meet Cameron Norrie in the quarters.

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. 

Top seed Daniil Medvedev made quick work of Mackenzie McDonald in his opening match at the Indian Wells Masters, cruising to a 6-4 6-2 victory on Saturday.

Medvedev – the US Open champion – has lost only three of his last 41 sets, and has never dropped one to McDonald in five career meetings with the American as he maintained his red-hot form. 

Russian star Medvedev is now 37-5 on hardcourts this year and appears well-positioned to make it past the third round of the ATP Masters 1000 tournament for the first time as he awaits Filip Krajinovic.

"I'm actually really pleased, because usually I haven’t played well in Indian Wells and I haven’t been playing that well in practices before [the tournament]," Medvedev said in his on-court interview. "[I am] really happy with my performance. That’s the most important [thing] no matter how I played before the tournament."

RUBLEV ROLLS PAST TABERNER

Medvedev's countryman Andrey Rublev closed out the night session with a 6-3 6-4 defeat of Carlos Taberner, who was facing a top-10 opponent for the first time. 

Fourth seed and world number five Rublev won 66 per cent of points on his first serve and hit 30 winners to Taberner's 12. 

Rublev improved to 47-16 this season, 31-9 on hard courts, and will face Tommy Paul in the third round. 

SHAPOVALOV WINS IN NEAR-WALKOVER

Most of the seeded players in action had an easy time of it, none more so than Canadian ninth seed Denis Shapovalov.

Shapovalov's opponent and countryman Vasek Pospisil retired with an apparent back injury after dropping the first three games of the match. 

Sixth seed Casper Ruud blew past Roberto Carballes Baena 6-1 6-2, while eighth seed Hubert Hurkacz downed Alexei Popyrin 6-1 7-5. 

Diego Schwartzman had to work harder to advance, the 11th seed outlasting qualifier Maxime Cressy 6-2 3-6 7-5. 

Top-ranked American Reilly Opelka, the 16th seed, beat Taro Daniel 7-5 6-3 for his first main-draw victory at Indian Wells in four attempts. 

Daniel Evans also went the distance to defeat Kei Nishikori 4-6 6-3 6-4, while former world number three Grigor Dimitrov, 2021 Australian Open semi-finalist Aslan Karatsev and Frances Tiafoe were among the other players to advance.

Andrey Rublev needed almost two hours but his punishing forehand helped him to victory over Diego Schwartzman in the San Diego Open quarter-finals on Friday.

Top seed Rublev won 6-1 7-5 in one hour and 52 minutes over the Argentine, who kept on coming throughout the contest.

The Russian world number five's victory books his spot in the last four where he will face Briton Cameron Norrie, who upset fourth seed Denis Shapovalov 6-3 6-1.

Rublev is featuring in his eighth semi-final of the calendar year and chasing his first title since winning in Rotterdam in February.

He had been a break up in the second set after dominating the first, but Schwartzman broke back.

The second set appeared destined for a tie-break with Schwartzman up 40-0 on serve at 5-6, before Rublev won the next five points to claim victory.

"The second set was very tough and enjoyable for the spectators to watch," Rublev said. "Every game was really tough with amazing points and the set could have gone either way."

Second seed Casper Ruud defeated Lorenzo Sonego 6-1 6-4 to book his semi-final spot where he will meet Grigor Dimitrov who beat Aslan Karatsev in three sets.

Ruud's win improved his 2021 record to 45-12, with the 22-year-old Norwegian rising to a ranking of 10.
