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.

Fritz defeated Medvedev in straight sets in Turin, although the American’s victory was overshadowed by the Russian’s behaviour.

U.S. Open finalist Taylor Fritz frustrated Daniil Medvedev to the point that that the Russian broke his racket and was docked a point in a 6-4, 6-3 victory for the American in the opening match of the ATP Finals.
