Defending champion Stefanos Tsitsipas remained tentative on Friday as he prepares to test a leg injury in the heat of battle at the ATP Finals.
The Greek lost his opening match at the Paris Masters last week as the injury flared again. And the ATP No. 6 admits that he is unsure of how it will hold up in London.
“I stayed a week in Paris for treatment,” he said in the run-up to the eight-man season wrapup which will be played inside a bio-bubble with no fans in attendance at the O2 Arena.
“I’m very close to 100 per cent, I can move more freely and I’m less conscious of the pain,” he said.
“But this injury has mentally drained me.”
The often-philosophical 22-year-old who will open play at the tournament on Sunday afternoon with a repeat of last year’s final against Dominic Thiem, said his leg problem has been a constant source of worry.
“”I’ve been struggling since Rome (September). I was not sure if it was the right thing to keep on playing.
“But I proved that the mind can do anything if you set a goal. I’m feeling way better than in Vienna (2nd round loss).
“I just hope the leg stays the same, I don’t want to go through what I went through a few weeks ago.”
