Top seed Daniil Medvedev powered his way into the Miami Open quarter-finals, along with Stefanos Tsitsipas and Andrey Rublev on Tuesday.
Medvedev won in straight sets against unseeded American Frances Tiafoe, hitting 24 winners.
Second seed Stefanos Tsitsipas won in straight sets against 24th seed Lorenzo Sonego, although the second went to a tie-break which the Greek dominated.
World number eight Andrey Rublev got past Marin Cilic in straight sets to book his last-eight spot.
Fifth seed Diego Schwartzman was the major casualty on Tuesday, losing to unseeded American Sebastian Korda in three sets. Seeds Josh Isner, Milos Raonic and Taylor Fritz also exited.
TOP SEED EASES INTO LAST EIGHT
World number two Medvedev was too good for Tiafoe in a 6-4 6-3 victory.
Medvedev improved his 2021 record to 17-2, sending down 11 aces with a dominant first-serve display while taking three of his four break points.
The 2021 Australian Open runner-up will meet seventh seed Roberto Bautista Agut in his maiden Miami Open quarter-finals appearance.
"It was definitely a tough match," the Russian said in his post-match on-court interview. "I am just looking forward to tomorrow. Roberto is a hell of a player.
"I feel like sometimes, when I have practised with him and played against him, that his ranking should be higher. There are reasons why it is not and I am going to try to do something with it tomorrow."
STEFANOS SIZZLES PAST SONEGO
Tsitsipas kept up his good form after making last month's Australian Open semi-finals, by booking his first Miami Open quarter-final appearance.
The Greek world number five defeated Sonego 6-2 7-6 (7-2) with a clinical performance to keep alive his dream of a maiden ATP Masters title.
Tsitsipas won in just over an hour and a half, proving too good on serve, having not offered up one break point and winning 89 per cent of first-serve points.
He was also too good with his return for the Italian, winning 35 per cent of the points on Sonego's serve.
The Greek will take on Polish 26th seed Hubert Hurkacz in the last eight, after he knocked out 12th seed Raonic 4-6 6-3 7-6 (7-4).
FIFTH SEED TOPPLED BY KORDA
World number nine Schwartzman was knocked out in three sets by Korda 6-3 4-6 7-5 as he continues his super run.
Florida resident Korda, 20, reached his maiden ATP 1000 quarter-final, showing fight after the Argentinian raised his game in the second set, winning after an early break in the last.
Rublev made light work of former US Open champion Marin Cilic, triumphing 6-4 6-4.
Bautista Agut got past 18th seed Isner 6-3 4-6 7-6 (9-7), while Jannik Sinner defeated Alexander Zverev's conqueror Emil Ruusuvuori 6-3 6-2.
Alexander Bublik, seeded 32nd, sent down 23 aces as he beat Taylor Fritz 6-7 (5-7) 6-3 6-4.
Alcaraz begins Madrid Open campaign with emphatic win
Carlos Alcaraz continued his fine record at the Madrid Open with an emphatic 6-2 6-1 victory over Alexander Shevchenko on Friday.
The two-time defending champion made it 12 straight wins at his home tournament to ensure he will face Brazilian Thiago Seyboth Wild in the last 32.
Alcaraz was playing his first match on the ATP Tour since March 28 after being unable to compete in the Monte-Carlo Masters and Barcelona Open due to an arm injury.
But he was still able to make a fine start to his clay-court season, breaking serve in the first game and racing to victory in only one hour and eight minutes.
Data Debrief
Sometimes the scoreline can be harsh on a beaten player, but on this occasion Alcaraz was clearly dominant, breaking the Kazakh seven times in the match and forcing 11 break-point opportunities while conceding only three for his opponent.
That allowed the Spaniard to claim a dominant victory despite being broken once in each set. He will now turn his attention to a clash with Seyboth Wild, who battled past Lorenzo Musetti with a 6-4 6-4 win.
Reigning champion Sabalenka pushed by Linette at Madrid Open
Aryna Sabalenka got her Madrid Open campaign started with a 6-4 3-6 6-3 win over Magda Linette on Friday.
Sabalenka could not quite hit her peak form against Linette, but the world number two nevertheless got the job done after going the distance.
The Belarusian is hunting a record-equalling third title in Madrid, where she is the reigning champion, though she has not won back-to-back matches at a tournament since winning the Australian Open.
"It's not about being confident," Sabalenka said. "It's about how much you're ready to do to get it. It's about the hard work and to be ready, be ready for the big fights. I feel like confidence is not going to help you in those big matches. It's about staying there and fighting for it."
Data Debrief
Sabalenka (70 per cent, 56-24) is now one of five active players since 2020 to hold a winning percentage of 70 per cent or higher at WTA-1000 events.
Iga Swiatek, Simona Halep, Elena Rybakina and Jessica Pegula are the other players to feature on that list.
Rybakina continues clay winning streak with victory over Bronzetti
In-form Elena Rybakina has moved into the last 32 of the Madrid Open after a straight sets victory over Italian Lucia Bronzetti.
Number four seed Rybakina triumphed 6-4 6-3 on Friday and will next face either Marta Kostyuk or Mayar Sherif.
Rybakina was broken early in each set but ultimately had few problems getting over the line, converting four of her five break points to continue an impressive run of results after winning the Stuttgart Open last week.
She has now won five consecutive WTA matches and has 13 straight wins on clay courts to her name in a superb streak that started one year ago.
Data Debrief: Rybakina in elite company
Since the start of 2020, only two other players have claimed as many 13 consecutive WTA wins on clay, and they are Iga Swiatek and Simona Halep, so Rybakina is in elite company.
Rybakina's last defeat on this surface came in the 2023 edition of the Madrid Open, when she fell to Anna Kalinskaya in her first match, so this win represented a better start to her campaign in the Spanish capital.
