Portugal Colonial - Nadal beaten again as Swiatek, Tsitsipas cruise at United Cup

There was also more misery for former world number two Alexander Zverev, who, like Nadal, suffered a second loss to start his season, this time at the hands of Taylor Fritz.

Spanish 22-time Grand Slam winner Nadal surprisingly crashed in his season-opening match on Saturday to 14th-ranked Cameron Norrie.

And he again succumbed after winning the first set, going down 3-6, 6-1, 7-5 to Australia's 24th-ranked Alex De Minaur in Sydney, including losing six games in a row in the second set.

"Honestly, I couldn't be happier that I managed to get my first win over Rafa on this court, it's no secret this is my favourite court in the world," said De Minaur.

"Rafa is a hell of a competitor and what he has been able to do for this sport is truly astounding so I'm just honoured. It's a dream come true."

It went with serve to 2-2 in the first set, but Nadal played some loose shots and a double fault handed De Minaur a break point, then he sent a forehand long to go 2-3 behind.

But the Australian couldn't sustain the pressure and Nadal broke straight back.

After a slow start, the Spaniard found his groove and in a devastating burst won the next three games to take the set.

De Minaur appeared deflated and was broken again on his first serve of the second set, but he flicked a switch to reel off six games in a row to leave Nadal stunned.

They exchanged breaks in the third set before a string of unforced errors from Nadal allowed De Minaur to break again for 6-5 and serve out for the win.

The mixed-team tournament features 18 countries playing in Sydney, Brisbane and Perth.

The winners of the two groups in each city advance to a city final on Wednesday, with whoever comes through that making the final four.

Neither Spain nor Australia can progress from Group D in Sydney, with Norrie's Britain already the confirmed winner.

They will play the United States in the city final after Fritz and Madison Keys put their country through against Germany.

- Rusty -

World number nine Fritz beat Zverev 6-1, 6-4 in just 64 minutes.

It followed the German's loss to 81st-ranked Czech Jiri Lehecka on Saturday in his first competitive match since tearing three right ankle ligaments during his French Open semi-final against Nadal in June.

"It was tough to judge my level because I feel he's coming back from injury, he's a bit rusty, he was giving me a lot of free points," said Fritz, who had a breakthrough year in 2022 with titles at Indian Wells, Tokyo and Eastbourne.

"But I'm really happy with it."

Keys swept past Jule Niemeier 6-2, 6-3.

World number one Swiatek gave Poland a 1-0 lead against Switzerland in a winner-takes-all tie that will decide Group B in Brisbane, beating Belinda Bencic 6-3, 7-6 (7/3).

"I'm a perfectionist, but I'm super happy with my performance today," said Swiatek.

"On this fast surface it was really, really hard so I'm really happy that I could close it."

Italy need a win against eliminated Norway in Group E to advance at Brazil's expense with Martina Trevisan delivering them an early lead by dispatching Malene Helgo 7-5, 3-6, 6-4.

In Perth, Belgium need to defeat Greece at least 4-1 to qualify from Group A and Alison Van Uytvanck held off an inspired Despina Papamichail 7-5, 2-6, 6-3 to give them a 1-0 lead.

But world number four Tsitsipas continued his good early form with a 6-3, 6-2 win over David Goffin to level the tie.

"Playing David is never easy," Tsitsipas said. "I was relaxed and hung in there point after point."
