Novak Djokovic maintained his flawless run at the ATP Finals following a 6-2, 6-1 win over Cameron Norrie.
The world number one started strongly and broke Norrie in the first game of the opening set. This gave Djokovic a platform to race to a 4-1 lead after just 18 minutes as he claimed the double break.
Djokovic continued to play at a high level, winning 92% of the points on his first serve and took the first set 6-2 in just 29 minutes to leave Norrie with a lot of work to do.
Norrie was broken in the first game of the set for a second time as Djokovic asserted his dominance. A double break saw the 34-year-old move 4-1 ahead and Djokovic broke for a third time in the second set to see it out 6-2, 6-1.
Saturday’s ATP Finals semi-finals will see Djokovic face Zverev with US Open champion Daniil Medvedev up against tournament debutant Casper Ruud in the other match.
