BEIJING - Novak Djokovic kept his juggernaut rolling at the China Open by improving to 26-0 with a 6-2 6-1 win over local hope Zhang Ze on Thursday which tied him with Jimmy Connors for the second-longest unbeaten record at an ATP Tour event.

The Serbian top seed, a five-time winner at the China Open, is now only behind Rafa Nadal who had a 31-0 run in the French Open at Roland Garros.

The world number one was unable to identify any particular reason for his performance at the tournament and said the conditions here were just in sync with his game.

"The conditions are definitely suitable to my game," Djokovic was quoted as saying by the ATP website (www.atpworldtour.com).

"I feel very pleasant playing on the centre court. I guess as I keep coming back each year with that positive record, obviously it gives me more confidence knowing that I played so well in the past on this court.

"I just keep on going. That's all. There is no particular reason. There are a few things that play in my favour."

Next up for Djokovic in the quarter-finals will be American John Isner, who snatched victory from the jaws of defeat against Australian qualifier John Millman.

The Australian was serving for the match at 6-5 in the second set but Isner broke back then won the tiebreak and then the deciding set for a 4-6 7-6(5) 6-4 win.
