Djokovic dazzles, Del Potro strains in Shanghai
Novak Djokovic and Roger Federer progressed in contrasting fashion at the Shanghai Masters but Juan Martin del Potro's bid for glory in China came to a painful end on Friday (AEDT).
A red-hot Djokovic eased to a 6-4 6-0 victory over Marco Cecchinato, avenging a surprise defeat against the Italian at the quarter-final stage of this year's French Open.
However, having needed three sets to see off Daniil Medvedev in the second round, Federer once again had to go the distance to reach the last eight, this time prevailing 6-3 2-6 6-4 at Roberto Bautista Agut's expense.
Del Potro, meanwhile, was forced to retire due to injury during his clash with Borna Coric, who will next face unseeded Australian Matthew Ebden - conqueror of Peter Gojowczyk - for a place in the last four.
Yet it was a good day for the big names on the whole in China, seeds Alexander Zverev, Kevin Anderson, Kei Nishikori and Kyle Edmund all winning in straight sets.
