Sinner sees off De Minaur while Fritz beats angry Medvedev at ATP Finals

• Sinner defeats Australian opponent 6-3, 6-4 in Turin
• Fritz triumphs 6-4, 6-3 in other Ilie Nastase Group match

Home favourite Jannik Sinner made the ideal start to the ATP Finals in Turin with a straight-sets victory over Alex de Minaur. Sinner recovered from losing his serve in the third game to ease to a 6-3, 6-4 victory in 85 minutes in his first match since winning the Rolex Shanghai Masters on 13 October.

He was playing great in the beginning of the match so I just tried to stay there mentally knowing that, hopefully, at some point my tennis would arrive," the world No 1 said in an on-court interview. It arrived quite early and I started to return very well, my serve for sure I have to improve but I'm very pleased about the win and hopefully this can give me the confidence for the next one."
