Stefanos Tsitsipas revealed he had defied the expectations of his doctor after surging into the Australian Open semi-finals.

The world number four underwent surgery on his right elbow in November and barely had any competitive court time leading into the tournament in Melbourne.

His doctor suggested that taking part in the first grand slam of 2022 was a remote prospect, but the Greek reached the last four on Wednesday after a 6-3 6-4 6-2 win over Jannik Sinner.

“I’m pretty sure my doctor is watching right now,” the 23-year-old said in his on-court interview.

“We both didn’t expect for me to be here, it was not part of our plan. He told me he didn’t see me playing in Australia but I proved him wrong.

“He’s a big tennis enthusiast and I am happy I found the right person to bring me back even stronger.”

Tsitsipas outclassed Sinner on Rod Laver Arena to move into a second consecutive Australian Open semi-final and third in four years.

The Greek will meet top seed Daniil Medvedev who defeated Felix Auger Aliassime in five sets.
