Shanghai - Roger Federer blazed into the Shanghai Masters semi-finals with a
6-4, 7-6 (7/4) victory over Kei Nishikori as the Swiss great's title
defence belatedly caught fire on Friday.
The 20-time Grand Slam champion and top seed will meet 13th seed
Borna Coric on Saturday after the Croatian defeated unseeded Australian
Matthew Ebden 7-5, 6-4.
The other semi-final tees up Novak Djokovic against young German star Alexander Zverev, just the second time they will have met.
The 37-year-old Federer was forced to battle through the first two
matches of his title defence, first to Daniil Medvedev and then Roberto
He put Nishikori under the cosh immediately, breaking the eighth seed
in the first game of both sets, though the Japanese did well to recover
and force the second-set tie break.
Djokovic said that he was relishing facing "top player" Zverev after
the 14-time Grand Slam champion beat Kevin Anderson 7-6 (7/1), 6-3.
Djokovic saved set point in the opener before taking control of the
tie break and the second set to dump out the South African seventh seed.
The 31-year-old from Serbia is in blistering form, winning Wimbledon,
the Cincinnati Masters and US Open in recent months, after having elbow
surgery in February.
The second seed is desperate to grab injured Rafael Nadal's year-end No 1 ranking.
Djokovic and Zverev met on clay in the final of the Rome Masters in May last year, the 21-year-old German winning 6-4, 6-3.
Djokovic, who endured a turbulent last season with injury and off-court issues, said they were "both different players" now.
"I wasn't - I feel like - playing as well as I'm playing today," he warned.
"But also he has improved a lot and he has established himself as a top player.
"It's going to be definitely a close match."
Touted as a potential future multiple Grand Slam winner, fourth seed
Zverev eased past Kyle Edmund to reach his first Shanghai semi-final.
The 6-4, 6-4 victory over the 11th-seeded Briton seals Zverev's place
in the season-ending ATP Finals in London next month, which bring
together the top eight men.
The top four players in the world - Nadal, Federer, Djokovic and
Juan Martin del Potro - had already qualified for London. Zverev is
Zverev, now under the tutelage of Ivan Lendl, said he is pleased with
his overall progress, even if a maiden Grand Slam remains elusive.
"I think every year you feel more mature. Every year you spend on tour, you feel kind of different," he said.
"Last year was the first time I kind of broke through to the top 10 and was a top-five player.
"It's always easier to get there - but then staying there is always the tougher part."
