Novak Djokovic ensured he will finish the year ranked world number one for an eighth time after battling to a late-night victory over Holger Rune in his opening match at the ATP Finals.
Djokovic is chasing a record seventh title but again found 20-year-old Rune, who is making his debut at the eight-man event, a troublesome opponent before pulling off a third win in five meetings.
It was past midnight in Turin when Djokovic completed a 7-6 (4) 6-7 (1) 6-3 victory after three hours and four minutes on court.
