Novak Djokovic beats Juan Martin Del Potro to win Shanghai title

World number two Novak Djokovic retained his Shanghai Masters title with a thrilling 6-1 3-6 7-6 (7-3) win over Juan Martin Del Potro.
The 26-year-old took advantage of the Argentine's sloppy service game in the first set before his opponent fought back to take the second and level.
Del Potro saved two match points in the 10th game of the decider, but the Serb proved too strong in the tie-break.
The Shanghai crown is Djokovic's fifth ATP Tour title of the year.
The victory also caps a good two weeks in the country for the six-time major winner, who came into the tournament having beaten world number one Rafael Nadal to land his fourth China Open title.
