Tsitsipas not playing singles unless "100%" at ATP Cup: "There's no reason for me to go out there and play"

Stefanos Tsitsipas played in the doubles rubber today for Greece at the ATP Cup but withdrew from the singles without playing.

This all stems from his recent elbow surgery as he looks to protect himself ahead of the Australian Open and while he is feeling good again, he admitted he won't play unless he's 100%.

"I'm truly relieved that I'm able to feel normal again after years and years of suffering. The concern was kind of something that I expected, but it's not serious. I'm just trying to protect it," he said.

"I've been using some muscles that I haven't been able to use before and it takes a little bit of time to get into the rhythm and get to the level I want to.

"If I'm not able to perform at 100%, for me there's no reason for me to go out there and play."
