Novak Djokovic secured a semi-final place at the ATP Finals with a 6-3 6-2 victory over Russian Andrey Rublev on Wednesday, Nov 17, his 50th match win of the year, while Stefanos Tsitsipas withdrew from the tournament due to an elbow injury. The Greek world number four was replaced in Turin by British world number 12 Cameron Norrie, who took Casper Ruud to three sets on his debut in the late match before the Norwegian prevailed 1-6 6-3 6-4.

Djokovic, who won his opening match against world number eight Ruud, was in early trouble in his first career meeting with Rublev when he was broken in the first game.

The Serb, looking for his sixth title at the season-ending event, was given an immediate reprieve when Rublev double- faulted to bring up two break points, the second of which Djokovic converted.

The pair were on an even keel until the eighth game when Djokovic pounced on a heavy volley from Rublev and sent a winning pass beyond the Russian to claim the vital break on his way to taking the first set.

The second was more assured from the world number one, forcing his opponent into errors that helped Djokovic to victory in 68 minutes, his 40th win at the ATP Finals.

The 34-year-old and 20-times Grand Slam winner tops the Green Group standings with two wins from two.

Djokovic will play Norrie on Friday while Rublev and Ruud meet in what amounts to a straight shootout for the last semi-final place.

“The good thing is that I qualified for semi-finals, so I won’t have that much pressure to win the match… but obviously every match matters, so I will go with the intention to win,” said Djokovic.

Ruud allowed the first set to get away from him before coming back strongly but Norrie still saved three match points in the final game to come back from 40-0 before the Norwegian served out.
