Garbine Muguruza heads a stellar line-up as she tries to capture her first tournament as world number one at the WTA Wuhan Open this week.

The Wimbledon champion lost heavily in the semi-final of the Pan Pacific Open to sixth-ranked Caroline Wozniacki on the weekend but is looking to make amends just two weeks after taking the top spot. "My best tennis wasn't here," she said after the 6-2, 6-0 defeat in Tokyo on Saturday.

"I'm not going to think about this loss too much. I still feel [Tokyo] was a good tournament for me to start the Asian swing," she said. The top seed faces a tough task in the Chinese city as eight of the world's top 10 are in action. U.S. Open champion Sloane Stephens and runner-up Madison Keys also return to competition for the first time since their Flushing Meadows final two weeks ago. Petra Kvitova is the reigning champion and is eyeing a Wuhan treble after he 27-year-old Czech also won here in 2014.

The battle to finish in the top eight and reach the WTA finals in Singapore next month is likely to dominate a hot and damp Wuhan, where world number two Simona Halep, fourth-ranked Karolina Pliskova, Wozniacki, Johanna Konta, Svetlana Kutnetsova, Jelena Ostapenko and Dominika Cibulkova complete the top eight seeds.
