Jannik Sinner had somewhat of a disappointing finish to this year largely affected by injuries. He is missing the Davis Cup Finals this week due to that but he's still able to do some tennis-related activities. In Monaco, where he lives, Sinner practised with Stan Wawrinka who had a pretty strong finish to the year indoors.
He's hoping to carry that form into next year and preparations started early. After their practice session, Wawrinka jokingly told Sinner to carry his bags but to be careful:
Rennae Stubbs defends Djokovic being left out of Stefan Edberg Sportsmanship Award: "Novak is not a great sport"
"Be careful with my nice Yonex bags please. Please take care of it, please."
"But this is not even heavy."
And Wawrinka added:
"Don't worry there's many bags."
