Novak Djokovic reached the semi-finals of the ATP Finals in clinical fashion against a frustrated Andrey Rublev.
The Serbian former world number one did not face a single break point in a 6-4 6-1 win over the Russian in Turin.
Djokovic left Rublev smashing his racquet on the floor at times with 69 minutes of ruthless tennis.
Victory came hours after his Australian visa ban was overturned to pave the way for the 21-time Grand Slam champion to play in January's Australian Open.
Djokovic made the breakthrough against Rublev in the 10th game to take the first set before embarking on what he described as a "flawless" second set.
