Novak Djokovic has advanced to the last 4 of the ATP finals by beating Russia’s Andrey Rublev in straight sets.
Djokovic fell-off to a shaky start after dropping Serve in the opening game but then he upped his tempo to break the Russian twice en route to a 6-3 win in the first set.
Serbia's World Number 1 continued with his dominance in the 2nd, grabbing it 6-2, to take his second consecutive victory in the Green Group, following his win over Norway’s Casper Ruud on Monday.
With Daniil Medvedev winning the Red Group on Tuesday, a possible World No. 1 versus No. 2 Final is on the cards for the 21st of November.
