Rafael Nadal has called for an overhaul to the United Cup format and hinted at potentially withdrawing from his side’s doubles rubber against Australia on the sixth day of the event.
Nadal was stunned by Australian star Alex de Minaur, who came from a set down to defeat the Spaniard on Monday night.
Spain’s losses so far in the tournament mean the side cannot progress from the group stage, but still has three matches to play in Sydney on Tuesday night, including a mixed doubles rubber Nadal is scheduled to play in.

After Monday’s loss, Nadal said the competition’s format needed review.
“Putting things in perspective (for) this competition, I find a negative point,” the reigning Australian Open champion said.
“Competition is great. Idea is great. It’s not great that today we are playing for nothing.
“It’s the first year of this competition, so that’s the kind of thing that we need to fix, to improve, and to make it more interesting for everyone.”
Key matchups at the United Cup on Tuesday include former world No.10 Pablo Carreno Busta up against breakout Australian Jason Kubler, while in Perth it will be Matteo Berrettini looking to start his season in style after injury hindered much of his 2022 campaign.
Nadal’s arch rival, Novak Djokovic, will make his singles return in Australia for the first time since being deported from the country last January, with the 21-time grand slam champion competing in the Adelaide International.
Djokovic, who lost in the doubles on Monday, faces 30-year-old French journeyman Constant Lestienne.
Later, Aussie young gun Rinky Hijikata will take on world No.18 Denis Shapovalov, while five-time Australian Open finalist Andy Murray will face son-of-a-gun Sebastian Korda.
