World No 2 Rafael Nadal was knocked out of the ongoing Australian Open on Wednesday in the quarter-final at the Rod Laver Arena. Nadal faced a 6-3, 6-2, 7-6, 6-4, 7-5 loss against Stefanos Tsitsipas. This is easily the biggest shock of the tournament. Nadal was expected to feature in the summit clash against World No 1 but that will not happen.

Nadal was in top form throughout the first week as he did not drop a single set. Nadal started off well as he won a couple of sets without dropping sweat and it seemed things are going to follow the predicted script. But, Tsitsipas had other ideas as he came back from behind to clinch the next three sets and pull off a massive upset.

Initially, Nadal was playing at his best as he was winning long rallies against the fifth-seed. In the first two sets, the Greek was not trying to get into rallies and was trying to go for the winner. From the third set, the fifth seed went back and was happy to get into rallies, and soon Nadal started tiring.

With the loss, Nadal’s bid for a record 21st Men’s Grand Slam title came to an end. The Greek entered the semi-final with the win.

After the game, Tsitsipas was at a loss for words to describe his win.

“I have no words to describe it,” said Tsitsipas, who also won the ATP Tour finals in 2019.

It was only the third time Nadal had lost after winning the first two sets.

Tsitsipas now faces Daniil Medvedev of Russia in the semifinal where the Greek will enter the clash high-on-confidence.

“It’s an unbelievable feeling to be able to fight at such a high level,” Tsitsipas said. “I can’t wait to play some good tennis.”
