TURIN (Reuters) -Italian world number one Jannik Sinner eased past Daniil Medvedev 6-3 6-4 in their final group match on Thursday, leaving Taylor Fritz to seal a place in the semi-finals of the season-ending ATP Finals after the American defeated Alex de Minaur 5-7 6-4 6-3.

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.

Jannik Sinner capped a perfect group stage at the ATP Finals with a 6-3, 6-4 win over Daniil Medvedev on Thursday which eliminated his Russian rival.
