World number two Novak Djokovic began the second leg of his China odyssey with an emphatic second round 6-3 6-3 win over Croatian Ivan Ljubicic at the Shanghai Masters.
Just 48 hours after reclaiming the China Open in Beijing on Monday, the second seed Serb donned once more a red dragon patterned kit and slayed the usually unyielding Ljubicic in 80 minutes.
The win underscores 23-year-old Djokovic's quest to replace Swiss maestro Roger Federer as the next-best to world supremo Rafa Nadal. The world's top quartet -- Nadal, Djokovic, Federer and Britain's Andy Murray -- are taking part in the tournament and play later on Wednesday.
Out of form number four Murray will be hoping to avoid an embarrassing upset against unknown giant killer Bai Yan. The young Chinese wildcard, ranked 465 in the world, on Tuesday claimed the scalp of number 30 Radek Stepanek.
Federer takes on American John Isner while Spaniard Rafa Nadal takes on Switzerland's Stanislas Wawrinka.
