Jannik Sinner claims ‘there is gap of improvement’ to be made despite ATP Finals victory
33 – Since the event’s change to best-of-three in 2008, Jannik Sinner (33) has now conceded the fewest games en route to the title at the ATP Finals, and the fewest overall since Ivan Lendl (27) in 1985 – excluding walkovers. Punctuation. #NittoATPFinals | @atptour @ATPMediaInfo pic.twitter.com/rE0TtyUaiW
