Top seeds Carlos Alcaraz and Iga Swiatek cruised to straight set victories at the Miami Open on Saturday while the home nation suffered a series of early exits.

Alcaraz and Swiatek Dominate

Spaniard Alcaraz was simply too much for his compatriot Roberto Carballes Baena as he powered to a 6-2 6-1 win in 85 minutes.

Alcaraz's Formidable Form

Alcaraz is looking to complete the "Sunshine Double" after his victory in Indian Wells last week and the two-time Grand Slam winner looked in formidable form.

Swiatek's Dominance

In the WTA event, Swiatek was even more dominant, beating Italy's Camila Giorgi 6-2 6-1 as the rain impacted tournament packed in the big names including postponed matches from Friday.

Swiatek's Progress

Swiatek needed just 67 minutes to cruise past Italy's Camila Giorgi 6-1 6-1 and the Pole was pleased with her progress.

Alcaraz's Next Opponent

Alcaraz has now won 11 straight matches against Spaniards but in the third round will face the winner of the contest between France's Gael Monfils and Australian Jordan Thompson.

Italian Success

Italy's Jannik Sinner, the Australian Open champion ranked third in the world, made a confident start to his bid in Miami with a 6-3, 6-4 victory over compatriot and qualifier Andrea Vavassori.

Defending Champion's Victory

Progress was also straightforward for defending champion Daniil Medvedev who advanced into the third round with a 6-4 6-2 win over Hungarian Marton Fucsovics.

American Setbacks

But it was a tough day for the American men. Taylor Fritz was upset by Brazilian qualifier Thiago Seyboth Wild in straight sets as three of the four top ranked US men tumbled out of the tournament.

Upsets and Retirements

Greek 10th seed Stefanos Tsitsipas also headed for the exit door at the Hard Rock Stadium after he was upset by 126th ranked Denis Shapovalov of Canada.

Unpredictable Matches

The 24-year-old Shapovalov snapped an eight match losing streak against top 20 players as he won back-to-back games at a Masters 1000 event for the first time since Cincinnati in 2022.

Murray's Victory

Britain's Andy Murray, a two-time winner in Miami, advanced to the third round with a 7-6 (7/0) 6-3 win over Tomas Martin Etcheverry.

Murray's Achievement

Murray, who has said he will probably retire later this year, celebrated with some passion after clinching the win, his first against a top-50 opponent since August.

American Woes Continue

American woes continued on the women's side of the tournament with Sloane Stephens crashing out to Romanian Sorana Cirstea who triumphed 6-2, 6-1.

Injury Retirement

However Jessica Pegula advanced to the third round after her opponent Zhu Lin had to retire ill while trailing 6-4, 4-1 in the second set.
