Rublev rolls on, Pliskova through to last 16 at Australian Open

MELBOURNE : Fifth seed Andrey Rublev avoided a third round banana skin in the form of Briton Dan Evans at the Australian Open on Saturday after former world number one Karolina Pliskova sailed into the last 16 of the women's tournament.

Red-headed Russian Rublev has found Evans a handful in the past but swept aside the 25th seed 6-4 6-2 6-3 with 60 winners on a glorious afternoon at Melbourne Park.

A quarter-finalist two years ago, Rublev had unleashed on the chair umpire in his previous match after being warned for an audible obscenity.

Pliskova, renowned for being a former world number one without a Grand Slam title, beat Russian Varvara Gracheva 6-4 6-2 in the early match at Rod Laver Arena to book a fourth round spot against China's Zhang Shuai.

Twice major finalist Pliskova missed last year's tournament after breaking her arm in a freak gym accident but victory over 23rd seed Zhang would continue the tall Czech's resurgence following her quarter-final run at Flushing Meadows.

"Last couple years were tough, especially missing it last year," she told reporters.

"I think the conditions here, they can be quite good for me."

In the bottom quarter of the women's draw, 12th seed Belinda Bencic continued her smooth run with a 6-2 7-5 win over Camila Giorgi in the second match at Rod Laver Arena.

Olympic champion Bencic has now racked up nine straight
