Shanghai - Two-time Grand Slam champion Garbine Muguruza won consecutive matches
for the first time since last year's French Open and plays Zarina Diyas
in the Shenzhen Open quarter-finals on Thursday.
The former world number one from Spain beat Shelby Rogers of the
United States 6-1, 7-6 (7/2) to avoid becoming the latest big-name
casualty in southern China.
"Every match is very important and it's great to start the year here
and get as many matches as possible," said Muguruza, 26, who has slipped
to 35th in the world.
Top seed Belinda Bencic of Switzerland and reigning champion Aryna
Sabalenka both lost on Tuesday, dealing a setback to their preparations
for the Australian Open.
Kazakhstan's Diyas, 75th in the world, booked her place in the last eight with a three-set victory over Russia's Anna Blinkova.
The Australian Open, the first Grand Slam of the year, begins in under a fortnight.
