For Jannik Sinner, it's the moment of truth at the Nitto ATP Finals in Turin: the world number 1 has also won against American Taylor Fritz, but qualification for the semifinals is not yet

The 24-time Grand Slam champion is not present at this year’s ATP Finals, having cited an injury as justification for his absence. Sinner will have to be especially careful with Alexander Zverev, who is very well in indoor conditions thanks to his excellent serve and has just won the Rolex Paris Masters.

It has been just over two months since Jannik Sinner defeated Taylor Fritz in the US Open finals. Much has transpired in the tennis world since then, but Sinner remains as dominant as ever.
