He’s got a stranglehold on the No. 1 ranking. He’s unbeaten this week and hasn’t dropped a set. And his home Italian fans can’t get enough of him. Things couldn’t get much better for Jannik Sinner at the ATP Finals so far — despite an ongoing doping case that likely won't be decided until early next year.

World number one Jannik Sinner continued his perfect start at the ATP Finals with a dominant win over Russian Daniil Medvedev. Playing on home soil in Turin, Sinner won 6-3 6-4 to top the Ilie Nastase group with three wins from three.

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.
