Portugal Colonial - Top Americans tumble out at Miami Open, Sinner sails through

Three of the top four ranked American players were eliminated during Saturday's opening session with Francis Tiafoe also knocked out and Tommy Paul retiring hurt.

Wearing the bright yellow of Brazil, Seyboth Wild, ranked 76th in the world and cheered on by loud support from his compatriots on stadium court, produced some impressive winners and some flamboyant shots on his way to a 6-3, 6-4 victory over 12th-seeded Fritz.

"I played a really solid match today, I barely missed," said Seyboth Wild after his win.

"It was exactly the plan with my coach before the match. I held up pretty well on the backhand and used my forehand to win the match," he added.

Fritz's early departure came shortly after Tiafoe went out to another lower-ranked player in Australian Christopher O'Connell.

O'Connell, battled to a 7-5, 7-6 (7/5) win over the 21st-seeded Tiafoe after play began following a three-hour rain delay.

Paul had to retire with an ankle injury in his match against fellow American, wild card Martin Damm. Paul had won the first set 6-4 and was 2-1 down in the second when he abandoned.

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.

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.

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.

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

The match had been at 3-3 in the first set when Friday's downpour forced the contest into Saturday. The 36-year-old Murray had lost his last two matches against the Argentine who is 32 places above the 62nd-ranked Scotsman.

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.

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.

Rain on Friday had led to the cancellation of the bulk of the scheduled matches, making for a packed schedule later on Saturday.

World number two Carlos Alcaraz and defending champion Daniil Medvedev were in action on the men's side and the top two ranked women, Iga Swiatek and Aryna Sabalenka, were also on court.
