Djokovic top of the world after sinking Rune at ATP FinalsNovak Djokovic is guaranteed to be world number one at the end of 2023. TURIN (ITALY) - Novak Djokovic will finish the year as world number one for a record-extending eighth time after beating Holger Rune 7-6 (7/4), 6-7 (1/7), 6-3 in his opening match at the ATP Finals on Sunday. Djokovic, on a run of 19 straight wins, has had an age-defying year, winning three Slams to become the all-time record winner of major titles. The 36-year-old came into the Finals in Turin off the back of his seventh triumph at the Paris Masters, his 40th victory at a Masters 100 event. On Monday Alcaraz makes his ATP Finals debut in the Red Group against Alexander Zverev, the second seed Djokovic's closest challenger.
