Novak has made a confident start to this match. He missed two break points in the fourth game of the opening set, but converted his chance in the sixth and then raced through a love service hold with an unreturnable first serve to consolidate the break and extend his lead to 5-2. The Serb took the set 6-3 in 31 minutes.
Djokovic broke his opponent’s serve twice in the second set for convincing 6-2 to leave himself firmly in control of the match.
The 23-year-old Belgrade native got off to the perfect start in the third set as he broke to 15. Nole got the double break on his third attempt in the fifth game when Lu hit a forehand into the net, and shortly after he closed the set and match 6-2.
